Gauge Bleed Valve GB1
Gauge Bleed Valve GB1
The ‘GB’ Type Gauge Bleed Needle Valve is designed for safe and reliable isolation, giving bubble-tight shutoff, with non-rotating, anti-galling tips 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 for simple calibration is included.
OliverValves Gauge Bleed valves provide metal to metal seating and a small-bore isolation valve for many applications while providing the option to bleed into the atmosphere.
The Gauge Bleed valve is supplied as standard with a non-rotating tip to allow linear closure while eliminating galling.
Oliver Valves’ standard Gauge Bleed valves are rated to 413bar (6,000psi) but can be rated at 689bar (10,000psi). Standard Temperature range from240 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.
The Gauge Bleed Valve 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.
