  • Choose The Right Industrial Gas Valve

    Industrial Gas Valves Industrial Gas Valves

    Gas valves are used to control the flow of liquids and gases. The gas valves are made from different materials, various sizes, different size of inlet and outlet connections, flow rate, pressure rating and the number of ports. The connection maybe unions, clamps, bolt flanges, butt or socket welds with internal or external threads.

    How are Industrial gas valves made?

    Industrial gas valves are made from metal or plastic. The outer part is called the seat which is hard while the inner lining is made of soft material to enable the valve to close tightly. The moving inner part of the valve that opens or closes is called the body and it fits into the seat. The valves open or close either by a handwheel, a manual lever or can be automated like in car engines.

    Valves are broadly classified as:

    • Angle valve release the content at an angle for maximum flow
    • Balancing valve maintains the consistency in temperature by compensating for the pressure drop
    • Ball valve encourages tight shutting off the gas valve
    • Butterfly valve offers unidirectional flow
    • Block and bleed valve
    • Diaphragm valve separates the flow of contents from the closing element
    • Diverter and directional valve guides the flow through a certain passage
    • Gate and globe valve shuts the valves with a linear motion
    • Metering valves are mixing valves that are used for specialized applications
    • Needle valve has a tapered point at the end of the valve stem
    • Stop cock valve is used for throttling applications

    Specialized industrial gas valves are:

  • The Water Is Not Hot Enough? The Dip Tube Needs Repairs Or Replacement

    The principle of heating water is that the water at the bottom gets warmed and rises up, getting replaced by a layer of cool water. This cycle goes on till all the water gets uniformly heated, only then it starts to boil and gets converted into steam. When heating water in a water heater installed in the bathroom, the same principle is followed, thermostat is set to not let the water boil to 100 deg C.


    If you are not getting enough hot water from your water heater or there is a loss of water pressure, chances are that the dip tubes may be defective. Dip tubes or Syphon tubes are tubes that direct the cold water to the bottom of the heating tank, while the warm water, which is lighter, automatically rises up.

    When there is a crack in the dip tube, the hot water mixes with the cold water and the temperature of the water is reduced. The dip tube gets corroded due to the pH of the water as well as the temperature setting, causing the dip tube to crack or break into pieces.

    Follow the steps to replace the dip tube, if you are not confident enough just call the plumbing company and let the trained professionals handle the job.

    Steps to replace the dip tube

    1. Turn off the power supply and unplug the wire from the socket. If you have a gas water heater, turn the dial to ‘off’
    2. Shut off the cold water supply valve, which is usually located at the top of the water heater
    3. Drain off all the water from the water heater tank. You can use this water to water your plants by attaching a pipe to the drain valve
    4. With a tubing cutter, cut the pipe between the cold water shut off valve and the water heater. Keep some rags handy as some water will spill on cutting of the tubing
      1. How to cut the tubing:
        1. Tighten the tubing cutter around the tube and gently rotate it
        2. Tighten it as the rotation is near completion
    5. With a pipe wrench, remove the pipe from the dip tube
    6. Check the condition of the dip tube, if it is not damaged, then the problem with the water heater may be due to something else. If the Syphon tube is corroded, cracked or broken, then it needs to be replaced
    7. Take the new dip tube and wrap the Teflon tape on the threads
    8. Replace the piping and put the dip tube in the water heater
    9. Open the cold water valve and fill the water heater tank
    10. Now, turn on the power and get the hot water at the right temperature and pressure

    Whether you are replacing the Syphon tube on a water heater or a CO2 tank, the same procedure has to be followed to repair or replace the Syphon tube.

    Old water heaters used plastic dip tubes which are prone to corrosion. Dip tubes for sale are available at the leading online portal, JTC Valve sales. Find the best deal for Syphon tubes on sale for carbon dioxide tanks too at this portal, who stock products made in the USA only.

  • To Produce Drinkable Beer, Choose The Right Carbon Dioxide Cylinder

    Carbon Dioxide Cylinders Carbon Dioxide Cylinders

    In a draft beer system, carbon dioxide plays a very vital role. To produce the perfect beer, the right carbon dioxide cylinders with CO2 regulators are a crucial tool for home draft systems. If you are looking out for CO2 cylinders for home brewing, keep in mind:

    • Efficiency
    • Portability
    • A space where you will fix the carbon dioxide cylinder
    • The size of the cylinder from 2.5 lbs to 20 lbs
    • Material used for the CO2 cylinder, either stainless steel or aluminum

    Understanding the compressed gas

    Gases like carbon dioxide, oxygen and nitrogen are compressed at room temperature. As the temperature reduces they become liquid or solid. As the cylinder gets heated, the gases expand, pressure increases and the cylinder gets hotter. This makes it necessary to have a good quality CO2 regulator.

    Carbon dioxide expands rapidly when the tank gets hotter. CO2 is filled at low temperatures ranging between -57 to -78 degrees at which the gas exerts a pressure of 100 PSI. At room temperature the pressure exerted on the walls of the carbon dioxide cylinder is 850 psi, which can go up to 2000 psi at 110 degrees.

    What you should consider for the draft beer system

    • What is the size of the CO2 cylinder you require
    • Keep the carbon dioxide cylinder and the beer keg cold as CO2 will infuse more efficiently at lower temperatures
    • The double gauge CO2 regulator is recommended so you know the gas that remains in the cylinder

    Models of CO2 cylinders available

    Carbon dioxide cylinders are available in different size from 1.25 lbs for service pressure of 1800 psi, manufactured from high strength aluminum alloy 6061-T6, with thread sizes from B5 and larger with 1.145 to 12 thread size.

    Understand the CO2 regulator

    There are two kinds of carbon dioxide regulators, single gauge and double gauge. The single gauge regulator is a primary regulator that lets the user control the gas flow. The double gauge regulator serves a dual purpose of letting the user control the gas output as well as let you know how gas still remains in the carbon dioxide cylinder.

    For a home draft beer system, you can use a single gauge regulator unless the tank is more than 20 pounds.

    Whether you are searching for CO2 cylinders or CO2 regulators, the most reliable and high quality carbon dioxide cylinders and regulators are available at JTC Valve sales. Every product available here is manufactured in the USA, approved by the CGA and comes with ISO standardization. To find any valve, cylinder, hose or regulator, simply visit JTC Valve sales and find the product that is reliable and safe for your use.

  • How to Replace a Shutoff Valve

    Shut-Off Valves Shut-Off Valves

    Shut off valves are also called as cut-out cocks. These types of valves have a wide application in almost all services. Shut off valves are widely used in air supply applications, drinking water application, oils and gas application, liquid fill or vent valve on cryogenic tanks as well as LNG fueling either as a protection device or as a control device.

    The shut off valves are of three types, the sweat valve, the threaded valve and the compression valve. Shut off valvesundergo frequent handling, which may cause problems after years of use. Rather than repairing the valve, it is beneficial to replace the shutoff valve so that the leakage, mineral deposit and corrosion problem does not reappear for years.

    Tools required to replace cryogenic valves

    • Pliers
    • Wrench
    • Soldering torch
    • Shut-off valve

    Here is a step by step guide to replace the shutoff valve

    1. Shut-off valves are usually connected to copper pipe by compression fitting or sweat fitting. Shut off the water by shutting the shutoff valve. Shut the electricity by shutting the circuit breakers. Drain out the water by opening the faucet. Remove the supply tube and replace the shutoff valve
    2. Identify the type of valve fitting. If it is a sweat valve, hold the valve with pliers, unscrew the valve system by loosening the packing nut. Remove the washer if it's stuck in the seat. Use the flame, if required to remove the valve
    3. Clean the tubing, solder the valve and sand off the traces of the solder
    4. To replace a compression shutoff valve, cut the sleeve at an angle and hack using short strokes so as not to cut the copper tubing. Remove the valve body with a wrench. Loosen the nuts, then pull off the valve from the copper tubing
    5. Slide the new compression nut and the sleeve onto the tubing. Insert the shutoff valve and screw the nut snugly into the new valve. Follow the instruction of the manufacturer as to how many turns the nut should be tightened

    Shut off valves extended stem valves are available at JTC valve sales. These extended stem valves are designed to be used as trycock valve or hose drain valve on cryogenic tanks. The one piece stainless steel stem, union bonnet and conical seat design allow the shutoff valve to work efficiently at pressures up to 600 psig at temperature ranging from -320 degree F to +165 degree F. This shutoff valve-extended stem is cleaned for oxygen service as per CGA G-4.1.

    JTC valve sales offers a complete range of valves, regulators and hoses for every application. When you buy from this leading portal, you not only get free shipping in the continental USA, but highly reliable, factory tested products that are made in the USA.
