A Single Isolated Valve Block and Capacitive Vent Plug Bleed Gauge / Instrument manifold, with pressure rated up to 10,000 psi / 690 bar. 

The valve is suitable for either panel or pipe mounting. The manifold design permits isolation and controlled venting of the instrument for calibration and or removal from the circuit, whilst leaving the process intact.
Features
  • Robust one piece body construction
  • Anti-blow out stem
  • Non-rotating, anti-galling tip as standard
  • Non-removable stem on the captive vent plug
  • Viton / RTFE stem sealing - maintenance free
