  • How Are Needle Valves Different From Flow Control

    Needle valves are a much-needed kind of valve in every gas industrial set up. The valves closely resemble globe valves in design and function except that they have a pointed end instead of the disk at the end of the valve system. It is the piercing point that possibly has given it the name – Needle Valves’. They are designed to control the flow of substances released by pressure, flow and direction and have the ability to shut-off the flow entirely. These valves actually turn 90° before it passes through an orifice followed by a cone-shaped tip to let the substance inside flow at low pressures.

    The Difference

    Both – the Needle valves & the Flow control valves are used to control the flow of air in the leg of a pneumatic circuit, which influences the actuator speed, and intentionally the flow is reduced. What differentiates the needle valves from the flow control valves is that the former is bi-directional whereas the latter controls the flow in one direction only.

    There is a finely threaded stem in both the fittings, which allows gradual adjustment of the quantity of controlled flow passing through the valve. The flow control fitting includes a simply by-pass feature that ensures a rapid and free flow.

    The Needle Valve Threads

    The four main categories of needle valves are - coarse, fine, wetted and non-wetted. Due to the fine threads, these highly functional valves offer an improved control. On the other hand, valves featuring coarse threads offer maximum flow and not enough precision. The wetted threads are exposed to the material/substance inside whereas the non-wetted threads remain dry as they are not exposed to any system.

    The Needle Valve Seals

    There are three types of seals used in the needle valves – metal, metal to plastic & metal to metal, that make them so useful. For regulation of gas flow, plastic to metal type of seal creates a larger seal area. If you want to regulate the flow of fluids, you can use the metal to metal seals.

    Needle valves, by their design & utility, are essentially required for industrial set-ups to allow pressure to be added/ relieved in very small increments.

  • How Dust Caps Prevent Connectors from Wearing Out

    Looking for the smallest details in the industrial equipment is really crucial. are tiny instruments that are used to protect the pins of connectors when there are no cables attached to the loose end. Made of plastic or metal, these connector caps also shield against electromagnetic interference EMI issues. Many of the metal valve caps  covercome with an attached chain to secure the chassis. The metal chain ensures that the cap is not misplaced when it is disconnected for cable attachment.

    DUST CAP AND CHAIN DUST CAP AND CHAIN

    Here are some important points to be considered while using dust covers:

     Check whether the dust cap with an environmental protection rating according to the recent industrial standards.

     A metal dust cap is great for protecting the chassis from EMI or noise.

     It is advisable to secure the dust cap to the chassis so that the cap is there the next time it is needed.

     It is important to ensure that the chain is of an appropriate length as a longer chain may cover or prevent access to other connectors.

     In case, the cover is not permanently attached to the connector, leave room on the back panel so that the chain can be attached to the rear panel.

     While inserting the pipe end caps on a ferrule, don’t insert it all the way since small dust particles can accumulate the bottom of the cap.

     The smaller the eyelet or attachment point is, chain attachment point takes up that much less amount of rear panel space.

    You need to perform an extensive survey of the kinds of dust covers available as here are different models of rim dust covers depending on the type of gas or liquid flowing through the material. To choose a dust cap with a chain or a plug & chain instrument depends on upon your specific requirements. Knowledgeable experts are the ones you need to consult here. JTC Valve Sales has been industry leaders in the supply of industrial regulators/valves and their accessories. Having more than 24 years’ experience in serving industry needs, JTC Valve Sales serves its clients in the best possible manner.

  • All-Purpose Compatible Thread Sealants for Industrial Needs

    Sealant tapes are adhesives that act as filler smoothening out surface irregularities or micro abrasions on threads. They possess lubricant qualities that allow the male threaded pipe to be deep turned deeper into female threaded fittings and prevent leakage.

    Pipe thread sealants are small accessories making a lot of difference in gas connections. But you need to choose a proper kind of plumbers tape for securing your gases and liquids.

    AN Threads provide a positive seal that connects rigid metal tubing and flexible hoses that carry fluid.

    National Pipe Thread is a US standard for tapered threads used on threaded fittings and pipes.

    Although there is no strict rule, we can categorize permanent or semi-permanent joints to identify appropriate applications:

    Permanent Joints – The joints that are installed during the rough-in phase of plumbing are permanent joints. Experts suggest tightening PIPE DOPES the threaded connections on the main & zone valves on the gas as well as water distribution systems.

    Semi-permanent Joints – These joints are a typically during the final trim-out phase such as shower heads, fixture angle stops, shower arms or any joint which would require general and regular maintenance. Here comes the use of pipe thread sealants/sealant tapes.

    What are PTFE tapes?

    The plumbing tapes underwent an evolution and double density versions became popular. However, the use of same ‘white’ color for two different thicknesses posed a challenge during inspecting job. Thus, the yellow Teflon tapes were introduced for such applications.

    Tape color Description
    Yellow double density often labeled as “gas tape”
    White should only be used on NPT threads up to 3/8 inch in diameter, can be single or double density
    Pink required on all joints 1/2″ or larger, triple density
    Green Oil Free PTFE tape, required for use on all lines carrying oxygen (i.e. – medical oxygen or welding oxygen lines)

    You had been using the sealant tapes for many years. But now, you have a deeper understanding of when to use a kind of pipe sealing tape. Check whether a specific sealant tape is compatible with oxygen or any material that you wish to pass through the thread surrounded by the tape. Oxygen compatible thread sealant tapes are apt for use with oxygen cylinders.

    So, if you are interested in purchasing a sealant tape, get it from https://www.jtcvalvesales.com/blog/Thread-Sealants/. JTC Valve Sales is a trusted dealer when it comes to industrial equipment.
