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.

SOLH VEX1133 high-flow precision relief regulator adopts combined nozzle-flapper pilot and balanced poppet structure. Compact in size yet with strong supply & exhaust capacity, it realizes ultra-fast pressure stabilization with negligible overshoot under sudden load changes and large downstream volume. It delivers ultra-high control precision with sensitivity ≤0.2% FS and repeatability ≤±0.5% FS, fully meeting micron-level positioning and constant force/tension process standards. Built-in overflow relief automatically discharges excess pressure inside closed air chambers to maintain stable set pressure without drift. Featuring friction-free internal components, lubrication-free and anti-contamination design, it allows arbitrary-angle mounting and supports standalone or manifold stacked assembly. Widely applied to film & wire tension control, pneumatic balancers, precision press-fit machinery and laboratory test bench constant pressure systems.

The Switchgear Drawer Interlock is a sophisticated safety device designed to ensure the secure operation and maintenance of electrical switchgear systems. This interlock mechanism is crucial for preventing accidental or unauthorized access to the switchgear components while the system is live or in operation. Made from high-strength, corrosion-resistant materials, the Switchgear Drawer Interlock offers reliable performance in demanding environments.
