Minimum Pressure Valves

Our manufactured Minimum Pressure Valves can be installed directly downstream from the air-oil separator. These provide two functions:
a cAt start-up, the value stays closed to a preset level and then opens to maintain a minimum pressure in the air-oil separator. This assures pressure for lubricating the compressor, reduces oil foaming and protects the air-oil separator element.
a cAt shutdown, the check valve closes to prevent back flow through the compressor.
