Ross 416K77 Service Kit

Ross 416K77 Service Kit is a valve body service kit built for Ross Controls 77 Series valve bodies. The 416K77 designation identifies a replacement kit used to rebuild the valve body rather than replacing the entire valve assembly. In marketplace listings this kit is sometimes described as “Valve Service Kit W/O Gasket,” indicating that some shipments exclude gaskets and that a gasket may need to be sourced separately. The kit is intended for routine maintenance and refurbishment of 77 Series valve bodies, helping authorized technicians restore sealing integrity and piston motion by replacing essential internal components as part of service work. Common applications include industrial process control and automation systems where Ross 77 Series valves regulate fluid flow, pressure, or directional control. To ensure proper fit, verify that the 416K77 kit matches your exact 77 Series valve model and body size; content and inclusion can vary by batch, so consult the seller or Ross technical resources to confirm whether a gasket or additional parts are included with your order.
