Directional control valves direct fluid flow to different paths by altering the spool position, thereby enabling actuator start/stop and reversal functions. These valves support multiple operating modes—manual, hydraulic, electromagnetic, or pneumatic actuation—to meet varying automation levels and operational environment requirements. Hydraulic and pneumatic directional valves offer material options including cast iron (for general applications) and carbon steel/stainless steel (for high-pressure and corrosive media), ensuring resistance to corrosion and mechanical wear even in harsh environments.

Valves operate at pressure ratings up to 210 bar (3000 psi), with high-pressure versions reaching 350 bar. The operating temperature range spans -40°C to +105°C, with optional seals enabling broader temperature adaptability. Directional control valves (such as miniature hydraulic directional control valves) must not only provide reliable sealing but also withstand high pressure, corrosion, and wear to ensure long-term stable operation under heavy loads or harsh conditions. Compatibility with multiple thread specifications and flange connections allows these valves to integrate into equipment systems conforming to various standards. Their applications span multiple industries including manufacturing, energy, chemical processing, marine engineering, and agriculture.
