It features a rugged, blue-painted cast iron body paired with a precision-machined steel mounting face to guarantee a secure, leak-free installation. Designed for seamless integration, the valve utilizes an industry-standard ISO 4401-style porting pattern. Its porting face includes four ring-sealed main port bores (P, T, A, B), visible seat bores, auxiliary pilot bores, and threaded mounting holes. The actuator end is built for durability, equipped with a hex-flanged cylindrical sleeve that is firmly secured by hex socket head cap screws. For easy traceability and maintenance, the mounting face includes a laser-engraved part number and a data matrix identification code.
