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 connect a calibration device, via a ¼’ NPT female connection is included.
Oliver Valves Gauge Vent valves provide metal to metal seating and a small-bore isolation valve for many applications while providing the option to vent to the atmosphere.
The Gauge Vent valve is supplied as standard with a non-rotating tip to allow linear closure while eliminating galling.
Oliver Valves’ standard Gauge Vent valves are rated 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.
All Oliver products 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.
Tips are ‘interchangeable’ without special tools or spindle changes in options of hard, soft and metering tips.
Safety ‘“ spindles are ‘back seating’ and ‘anti-blowout’ as standard, a major safety feature. An anti-removable’ steel pin is fitted into the body so that the head unit cannot be removed inadvertently.
Dust cap protects spindle threads from ingress of dirt and is colour coded for particular service.
