Product Description

NAI-LOK SS316 High Pressure 3-Valve Instrument Manifold Valve 6000 PSI for Pressure Transmitter Systems

Product Description

The NAI-LOK 316 Stainless Steel 3-Way Valve Manifold is designed for precise control, isolation, and equalizing functions in pressure transmitter and differential pressure transmitter systems. It provides a reliable connection between process pipelines and measuring instruments, ensuring stable pressure transmission and safe system operation.

Manufactured from high-quality SS316 stainless steel, this manifold valve offers excellent corrosion resistance, high mechanical strength, and long service life, making it suitable for demanding industrial environments. With a pressure rating up to 6000 PSI, it ensures safe and stable performance in high-pressure instrumentation applications.

The 3-valve configuration includes isolation, equalizing, and vent functions, allowing safe installation, maintenance, and calibration of pressure transmitters without system shutdown. The compact and robust design makes it ideal for oil & gas, petrochemical, chemical processing, and industrial automation systems.

This instrumentation manifold valve is widely used in pressure measurement systems where accuracy, safety, and reliability are critical.
