Product Description

 

NAI-LOK  High Pressure Instrumentation Valve 3 Way Stainless Steel Manifold 6000 psi for Chemical Plant

Product Description

The NAI-LOK High Pressure 6000 psi Stainless Steel 3 Way Block and Bleed Valve Manifold for Instrumentation is designed for direct mounting with pressure gauges, transmitters, and instrumentation systems. Manufactured from corrosion-resistant Nickel-Copper Alloy 400, this valve manifold provides superior durability in highly corrosive environments such as offshore oil & gas, petrochemical, and marine applications.

Available in R (Remote Mount) and T (Direct Mount) types, the manifold enables safe isolation, calibration, and venting of pressure instruments. Its precision-engineered needle valve stems ensure leak-tight shutoff, while the rugged forged body construction delivers long service life under high-pressure conditions.
