China SOLH VEX1133 industrial precision regulator Manufacturer, Supplier, Factory

SOLH 3L series 3/2-way hand pull directional control valves follow standard industry specifications with a default Normally Closed (NC) structure equipped with automatic spring return. Operated via straightforward axial push-pull handle movement, this manual pneumatic valve requires no electric parts or pneumatic drive signals, making it an intrinsically safe manual switching component for pneumatic circuits. It is widely deployed for single-acting cylinder actuation, circuit on-off switching, inching commissioning and safety interlock systems, especially ideal for field debugging, emergency cut-off and explosion-prone working environments. The three-port layout complies with universal industry standards: P for main compressed air inlet, A for working output port connecting single-acting cylinders, and R for exhaust port compatible with standard silencers to reduce exhaust noise. Under normal released status, the built-in return spring presses the precision spool to seal the P inlet; port A links to R for pressure relief to maintain the closed safe state. Manual pulling of the handle shifts the spool to connect P and A ports for air supply to drive cylinder movement. Once released, the spring instantly resets the valve, cutting air intake and exhausting residual pressure to prevent unintended continuous operation. Constructed with robust aluminum alloy housings and low-friction precision spools, the valve supports lubrication-free operation with stable sealing performance. Four size grades ranging from compact 3L100 up to heavy-duty 3L400 cover thread specifications M5, G1/8, G1/4, G3/8 and G1/2; PT, NPT and G thread options are available to satisfy global installation demands. The valve supports panel mounting and base mounting, sharing identical installation dimensions with the 3A air-operated valves for seamless interchange between manual and pneumatic control modes. Without any electrical components, it delivers spark-free operation suitable for flammable, dusty and humid workshops, commonly used for manual clamping, ejection cylinder control, equipment maintenance safety lockout and combined manual-pneumatic logic control systems paired with 3A pilot valves.

The Switchgear Remote Control Panel is an integral component designed for the operation and control of switchgear systems. This controller facilitates the smooth maneuvering of the switchgear trolley, allowing for efficient and safe handling of electrical panels during installation and maintenance. Featuring a user-friendly interface, the controller allows operators to easily manage various functions, such as movement, locking, and unlocking of the trolley, ensuring secure positioning of the switchgear. It is built with robust materials to withstand the rigors of high-voltage environments, while also providing reliable performance and durability. Compatible with a range of switchgear configurations, the panel trolley controller is essential for optimizing workflow and enhancing safety in electrical substations and industrial settings. Its design adheres to international safety standards, making it a trusted choice for professionals in the electrical industry.
