Gauge Valve - 1 (GV1)

A safe & economical method of installing pressure switches, gauges and differential transmitters block and bleed for purge valve, sampling lie and safe pressure source.

Outside screwed bonnet design.
Back seating of stem in fully open position prevents stem back-out.
All types of valves have a self-centering, non-rotating needle on the valve seat, alternative seating to choose for every application requiring bubble tight shut-off.
Safety stop pin (SS316 pin prevents detachment of the bonnet from the body due to vibrations).
Bonnet-to-body seat, metal to metal seal eliminates the need of 'O'-Ring seals.
Dust cap with colour identification.

Standard pressure rating up to 6000 psi (413 bars).
Standard PTFE packing and optional Graphoil packing for higher temperature services.
Temperature rating for PTFE 450ºF (232ºC) & for Graphoil 1000ºF (538ºF).

Hydrostatic test: Body 1.5 times - 9000 psi (620 bars) & Seat 1.1 times - 6600 psi (455 bars).
Pneumatic test: Seat - 1000 psi (69 bars)
Valve is tested with nitrogen at 1000 psi for leakage at the seat, to maximum allowable leak rate of 0.1scc/min.
