Leading SS 304 instrumentation needle valves manufacturer in India

Stainless Steel Needle Valve

Stainless Steel Needle Valves are used for flow regulation, metering, and leak-tight shutoff in severe oil and gas, power, chemical, and petrochemical applications up to 10,000 psig (689 bar) and 1200°F (648°C).

A Stainless Steel Compression Needle Valve is a type of valve that has a small port and a needle-shaped threaded plunger. The plunger on the Needle Valve is shaped like a needle. The 1/2 Inch Stainless Steel Needle Valve has the advantage of allowing precise flow regulation. Despite the fact that the 1/4 Stainless Steel Needle Valve can only handle relatively low flow rates. With the help of a spindle, the Ss-1rs4 Needle Valve can control and regulate the flow.

We are stockist of 316 stainless steel needle valve in pressure range of 6,000 psi to 10,000 psi

The CF8 Stainless Steel Flanged Needle Valves are available in a variety of sizes. The end connection can be 1/8 inch to 12 inch. End connections for various types, such as the 1/4 Inch ASTM A351 CF8M 316 Needle Control Valve, can be duolok, unilok, griplok, tube fitting, or trufit pipe fitting. We supply various types as a leading supplier, including the A351 CF8 304 Water Flow Control Needle Valve and others. Straight and angled valves are available. Please contact us for more information and pricing on the various types, including the High Temperature Needle Valve and others.
