Ross Controls W742K87 Valve Service Kit For W70 To W74 Series

The Ross Controls W742K87 Valve Service Kit is a complete OEM repair kit for rebuilding ROSS W70/W74 series pneumatic directional control valves, replacing worn seals, gaskets, springs, and internal components to restore spool movement and sealing integrity. It is designed for base-mounted or manifold-mounted, aluminum spool-and-sleeve valve bodies and uses Buna-N seals for filtered compressed air in 5-port, spool-and-sleeve designs. The kit contents include seals, gaskets, springs, spacers, bumpers, lubricant, and spool/sleeve components (kit dependent) and is commonly applied in industrial automation systems such as stamping presses, manufacturing lines, material handling, and packaging machinery to ensure leak-free operation. Maintenance teams, OEM service engineers, and system integrators use this kit for valve refurbishment, preventive maintenance, and restoration of pneumatic control performance.
