SOLH VCH400 (VCH410) series pilot operated 3-port poppet solenoid valve is customized for medium & high-pressure gas pipelines with max operating pressure up to 5.0MPa. Equipped with high-pressure polyurethane elastic seals and large-size ISO G threads (G1/2, G3/4, G1), it delivers high flow capacity and ≤±2ms response deviation, with outstanding vibration & shock resistance and 10-million-cycle service life. Drip-proof structure reaches equivalent IP65 protection; the NC version automatically vents upon power loss, ideal for high-pressure charging, venting and pressure conversion circuits, and perfectly matched with SOLH VCHR high-pressure regulators. Only applicable to clean dry compressed air and inert gas. Coil-down mounting is prohibited, and periodic cycling actuation is required to avoid poppet adhesion. It serves as reliable control component for industrial high-pressure air charge & vent equipment.

SOLH 4H series hand lever directional control valves are developed in accordance with mainstream industrial standards, covering 5/2-position and 5/3-position configurations. Operated purely by manual lever manipulation without electromagnetic coils or pneumatic pilot signals, these spool-type manual valves are widely adopted for on-site equipment commissioning, emergency safety shutdown and inching control of double-acting cylinders. Constructed with high-strength aluminum alloy housings and precision spool assemblies, two positioning structures are optional: automatic spring return and steel ball mechanical locking. Crucially, the mounting dimensions are fully consistent with 4V solenoid valves and 4A air-operated valves, enabling direct interchange and flexible switching among electric, pneumatic and manual control modes in standard pneumatic systems. The five-port layout complies with international general specifications: P serves as the main compressed air supply inlet; Ports A and B connect to two cavities of double-acting cylinders to govern extension and retraction movements; R and S are exhaust ports compatible with standard silencers to lower exhaust noise. For 5/2-position models, spring-reset variants automatically rebound once the lever is released to deliver foolproof protection against unintended continuous actions; self-locking versions secure the spool position via steel ball positioning and stay latched until manual switching, ideal for long-duration fixed working states. All 5/3-position units adopt dual stable ball positioning with three configurable neutral modes. Closed Center (Type C) seals all ports to lock cylinders and prevent falling of vertically mounted actuators; Exhaust Center (Type C) vents A/B ports for pressure relief, allowing free cylinder floating during manual testing; Pressure Center (Type P) supplies compressed air to both working ports for synchronous clamping and force balance regulation. Running on filtered compressed air within 0.15~0.8 MPa under lubrication-free conditions, the valves work steadily at -20℃ to +70℃. Available specifications range from 4H200 to 4H400 with multiple thread options. Devoid of electrical components, the valves feature spark-free inherent explosion resistance, well-suited for flammable, dusty and high-risk production sites. They support panel mounting and base installation, frequently applied for production line manual commissioning, emergency pneumatic circuit cut-off, safety interlock loops and retrofitting replacement of automatic control valves.
