adjustable pressure valve

adjustable pressure valve

The features of adjustable pressure valve can be summarized as Body (Standard materials are stainless steel, brass, and PVC for low pressures); Piston(The stainless steel pressure valve for gases and liquids and brass pressure gas valve are standard); Spring(Stainless Steel is the standard construction for a brass air pressure valve and stainless steel for a liquid pressure valve); Lock nut(Standard construction is stainless steel, even when used with a brass body); Elastomeric seal(Bubble-tight seal is achieved with soft elastomers such as Buna, Viton, and EPDM and Kalrez, but not with the harder seal material, Teflon (PTFE)); Tamper-proof construction-This valve is not externally adjustable & requires removal of the valve to change the pressure setting and Adjustable pressure-setting valve can be factory-set or adjusted in the field. Spare springs can be changed in the field to achieve a different pressure range.

This valve is normally used for liquids, air, or gases which cannot be safely discharged to atmosphere. Where the discharge can be directed to the atmosphere, please refer to our model RVA-05 series valves. Use only clean filtered or strained liquids or gases. The valve can also be used for vacuum relief service where the vacuum is connected to the internal thread side of the valve. Select the appropriate spring range converted to psi to correspond to the vacuum level desired.

The Material for adjustable pressure valve are Body(Brass & SS), Poppet(Brass & SS), spring(Stainless steel), Guide(Brass & SS) and Nut(stainless steel).
