Ross Controls W742K87 Valve Repair Service Kit

Ross Controls W742K87 Valve Body Kit is a rebuild kit for Ross ANSI W70 series 5/2 valves (body size 4). It covers port sizes from 3/8 in to 3/4 in and uses Buna-N seals, making it suitable for general industrial pneumatic installations where valve integrity and leak-free operation are critical. Contents include gaskets 356B11, two 557B11, one rubber gasket, one spring, two spacers, two bumpers, one spool and sleeve assembly, and lubricant, enabling replacement of worn wear parts without replacing the entire valve. The kit supports servicing Ross W70-series valves in process control, automation, and machine tooling applications, helping technicians reestablish proper sealing, alignment, and actuation response. Designed for field technicians and maintenance personnel performing on Ross ANSI valves, the W742K87 enables on-site refurbishment of W70-series valves while preserving compatibility with the original valve body design. Before purchasing, verify that your specific valve model matches the W742K87 kit scope and that the port sizes and seal materials align with your equipment’s requirements.
