G12AF Gauge Valve
G12AF Gauge Valve
The ‘G12AF’ Type 2 valve manifold is designed for remote mounting to static pressure transmitters. The angled heads allow for panel mounting. The separate vent valve gives full control of venting of the instrument, plus the ability to calibrate in-situ. Each needle valve head is designed for safe and reliable isolation, giving bubble-tight shutoff, with nonrotating, anti-galling tip and dynamic self-adjusting spindle seal to give long service life in a variety of service conditions. Oliver Valves G12AF, Female x Female, the valve provides metal to metal seating and a small-bore isolation valve for many applications while allowing venting to the atmosphere and being suitable for panel mounting.
The G12AF gauge valve allows isolation, calibration and venting within a single unit, hence eliminating leak paths.
The G12AF gauge valve is supplied as standard with a non-rotating tip to allow linear closure while eliminating galling.
Oliver Valves’ standard Gauge valves are rated at 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. There is an anti-removable steel pin fitted into the body so that the head unit of the valve cannot be removed inadvertently.
Dust cap protects spindle threads from ingress of dirt and is colour coded for particular service.
