Descrption
Single unit system lowers installation costs, reducing labor and materials.
Simple blanket pressure setting with one unit to calibrate as opposed to conventional multi-unit systems.
Reduced maintenance costs as top entry provides access to all internal parts without removal from the line.
Optimum performance reduces supply gas pressure from 200 psig (13.8 barg) to ½” wc (1.2 mbarg) in one stage.
Balanced design maintains setting accurately regardless of pressure variations.
O-ring seat and seals assure bubble-tight shut-off.
Single-source solution provides pad and de-pad valves, regulators, pressure/vacuum vents and low pressure pilot operated valves, emergency vents and valves, flame and detonation flame arresters.
Combined de-pad and pressure relief valve functions minimizes number of valves and tank connections.
Component compatibility enables the provision of all major system components in a single tank penetration.

Description
Pilot control keeps high seat forces all the way to set pressure point, helping eliminate product losses.
Snap action opening permits full opening at set pressure, allowing higher settings and overcoming freezing or sticking problems.
Choice of rapid snap opening and proportional modulating action pilots to suit the process.
Extensive selection of resilient seat and diaphragm materials to meet most conditions and provide long maintenance free operation.
Balanced against back pressure enabling connection to closed header systems without loss of valve lift or set pressure fluctuations.
Remote sensing option allows accurate pressure sensing regardless of inlet piping pressure losses.
Field test connection enables valve function verification in place without removal to a test bench or raising process pressures.
Manual blowdown enables manual or remote actuation to depressurize a system.
ASME UV Code Stamp for set pressures above 15 psig.
