brass gas needle valve

     Brass High Pressure Instrumentation Needle Valve,3000psi

●Brass high pressure instrumentation needle valve are designed to regulate flow to an instrument or other industrial application..open or cut off the pipeline path. They are rugged enough for the oil & gas market

●It can be used to open and close the propane. If you need a long time and stable control, it would be better to use with a regulator.

●This straight instrument needle valve Made of high-grade solid brass, exquisite processing, can withstand greater pressure than other types of valves, good sealing performance, if you need a long time and stable control, it is best to use it with a regulator

●●Compact size valve built for maximum durability

Valve body machined from brass bar stock

●100% helium leak tested to 1 x 10-4 ml/s for guaranteed performance

●FKM o-ring seal and PTFE back-up ring below the stem threads to protect from corrosion and galling; ●PTFE packing optional

●All stems are 316 stainless steel

●All stem threads are rolled for strength and ease of operation

●Patented body-to-bonnet, metal-to-metal seal is designed to significantly increase the pressure range of the valve

●Every valve is tested in the laboratory for 100% reliability ,every valve thread use thread protector to protect their thread that make use life more long .

●This valve is widely used in gas service industry where precise control of flow is required

●Used to control flow in delicate gauges that may get damaged if there is a sudden surge of pressurized fluid

●It used in applications where the flow is to be brought to a halt gradually

●Can be used for throttling service

●Needle valves are widely used in the following industries

• Power generation

●Logo can laser or engrave on the valve body . logo letters according to customer requirements

●Loading Port: shanghai /Ningbo port china

1)The installation position, height, and direction of inlet and outlet must meet the design requirements. For the direction of medium flow, please refer to the arrow marked on the valve body. Inlet: 1/4"" NPT female, outlet: 1/4"" NPT female, The connection should be firm and tight.

2)Visual inspection must be carried out before valve installation. For valves with a working pressure greater than 1.0 MPa and a cut-off function on the main pipe, the strength and tightness test should be carried out before installation, and then used after being qualified. During the strength test, the test pressure is 1.5 times the nominal pressure, and the duration is not less than 5min

3)If it leaks, you can replace the internal O-ring with pliers, or it is recommended to seal both ends with a little Teflon tape.
