Description



The ‘GV’ Type Gauge Vent Needle Valve is designed for safe and reliable isolation, giving bubble-tight shutoff, with non-rotating & anti-galling tip and dynamic self-adjusting spindle seal to give long service life in a variety of applications. The additional ability to bleed the gauge cavity to the atmosphere and also connect a calibration device, via a ¼” NPT female connection, is included.

This gauge valve provides metal-to-metal seating and a small-bore isolation valve for many applications while providing the option to bleed to the atmosphere.

The gauge valve is supplied as standard with a non-rotating tip to allow linear closure while eliminating galling.

The standard gauge valves are rated to 413bar (6,000psi) but can be rated at 689bar (10,000psi).

Standard Temperature range from 240 Deg C up to 540 Deg C.

All NPT connection threads are Single Point CNC machined.

Have material traceability and pressure test certificates to BS EN 10204 3.1. 

A unique code is stamped on all valve bodies linking them to their material and chemical analysis certificates.
