ROSS Controls, Inc. 743K77 Valve Body Repair Kit

ROSS Controls 743K77 Valve Body Kit is a complete service package designed for W74-series ANSI pneumatic valves, specifically a 5/2 valve body with a body size of 10, built to support durable operation in general-purpose industrial applications. The kit accommodates port sizes ranging from 3/4" to 1-1/4" and uses Buna-N seals, a combination chosen for reliable sealing and compatibility with standard compressor air pressures used in typical factory settings. Intended for reconditioning W74 valve bodies, this kit helps restore proper actuation, seal integrity, and overall performance across common pneumatic circuits. As part of Ross Controls' valve body service offerings, the 743K77 aligns with the company's broader line of W74-series service kits, providing the essential components required to refresh a 5/2 valve body and bring it back to specification for general-purpose operation.
