Your specialised source for minimum-pressure check valves designed specifically for screw compressors.<\/p>\n
We supply high-quality valves installed at the outlet of the oil separator tank to maintain the minimum internal pressure required\u2014typically between 4 and 4.5 bar\u2014for effective lubrication of the air end during startup. They also prevent compressed air from flowing back from the air network into the compressor when the unit stops.<\/p>\n
Key Features of Our Minimum-Pressure Valves<\/p>\n
Lubrication System Protection During Startup: Rapidly builds internal tank pressure to circulate oil to the rotors and bearings immediately after startup, protecting them against premature wear.<\/p>\n
Integrated Non-Return Function: Prevents compressed air from flowing backwards from the receiver tank or air network into the compressor during unload mode or shutdown.<\/p>\n
Accurate, Calibrated Operation: Equipped with a precision spring and oil- and heat-resistant PTFE seals, ensuring accurate opening at the specified pressure.<\/p>\n
Robust Engineering: Manufactured from reinforced aluminium alloys or high-quality brass to withstand demanding operating pressures and temperatures.<\/p>\n
Easy Maintenance and Extensive Coverage: Internal repair kits can be replaced easily, while complete OEM-equivalent valves are available for leading brands, including VMC, Hoerbiger, Atlas Copco, Kaeser, and Ingersoll Rand.<\/p>\n
