Description
The unloader valve kit is a full set of replacement spare parts specially for overhauling the unloader valve of piston & screw air compressors.
It normally includes sealing gaskets, rubber diaphragms, return springs, O-rings and small wear parts for valve assembly, covering all vulnerable consumables of the unloader valve.
Fitted on the air compressor unloader valve, these parts help the valve automatically vent residual trapped air inside pump head and pipeline once the compressor cuts off at preset maximum pressure. It eliminates back pressure so the motor restarts under no heavy load, avoiding motor burnout and excessive power consumption. When tank pressure drops to lower limit, the valve closes to resume normal air compression.
Compatible with most mainstream piston and screw compressor brands. Replacing worn parts with this repair kit restores original valve performance, cuts maintenance cost compared with full new valve replacement and stabilizes whole compressor running efficiency.
