Bar Stock Needle Valve Male-Female NPT

Bar Stock valves are suited to shutting off the impulse line and for mounting pressure measuring instruments. As a standard, the valves feature external stem threads and ½ NPT connec - tion threads. Other connections are available on request. For venting the measuring line, the barstock valves have an additional vent hole, which is sealed with a bolt when deliv - ered (see drawings on reverse). Block and bleed valves also have a separate vent valve.

We are the trusted name in the industry when it comes to the manufacture and supply of valves, fittings and industrial couplings with adapters. We have served a wide variety of industrial sectors, and supply products which conform to industry standard requirements and ensure safety and system efficiency with their precision design. We offer an extensive product portfolio, and are also trusted manifold valve manufacturers, who offer reliable products for high end system efficiency. We understand the importance of durable quality in industrial valve and fitting design, and that is why we never compromise on quality.

With rich expertise, we are offering a wide range of Needle Valves that is generally used in flow metering applications, especially when a constant, calibrated, low flow rate must be maintained for some time, such as the idle fuel flow in a carburetor. Our needle valves are appreciated in the market for low operating torque and high tensile strength. Further, these are provided in proper packaging to the clients in order to prevent wear and tear during transportation. Needle Valves or Shut-Off Valves are designed to Isolate, Calibrate and Drain Process Lines by Line Mounting.
