Blowdown Valve Repair Kit




Our Sullair Replacement Blowdown Valve Repair Kit contains all the necessary seats and o-rings for repairing blowdown valve # 409783 on all LS-25S Series Compressor Models.

eCompressedair provides quality Sullair replacement parts that meet or exceed the OEM specifications. Aftermarket parts are more cost effective than brand name parts and can typically allow for a reduction in your annual maintenance costs over the life of the compressor.

How it Works

Blowdown valves are usually installed downstream from the air/oil separator and performs a couple of critical functions. At start up the valve closes to allow the separator pressure to build up, and during unloading and shutdown the valve opens to bleed the pressure into the atmosphere. The blowdown valve may also be used as a bypass valve to bleed air through the compressor during start up.

In a compressor environment, significant pressure and mechanical/thermal stresses are placed on the blowdown valve. All of these factors wear down valve components, and as a result the o-rings and seats naturally become worn over time. At this point it is advised to either repair or actually replace the blowdown valve to avoid costly leaks.
