China Electrical Switchgear Orienting Pin Manufacturer, Supplier, Factory

SOLH HFR pivot-linkage 180° wide-opening pneumatic gripper is driven by piston linkage to rotate jaws. Each jaw swings up to 90°, forming a straight line when fully opened to provide maximum clearance and eliminate mechanical interference during pick-and-place. Bore sizes cover 10/16/20/25/32 mm with purely double acting design. The -2°~-5° overclose angle ensures stable clamping. Three mounting surfaces (side, bottom, rear) are available; locating pin holes on the base improve assembly accuracy, and suffix-N through-hole mounting is optional. All models come with built-in permanent magnets and sensor grooves compatible with CMSH magnetic switches. Optimized dust-proof jaw structure and anti-friction metal separators deliver service life over 5 million cycles for moderately dusty workshop environments. Widely used for gripping and turnover of deep-cavity workpieces, large plastic housings and box materials. MHW2 gear-driven swing gripper can be considered for medium-load applications if extreme avoidance clearance is unnecessary. A minimum 30% safety margin must be reserved during torque calculation; extended jaw overhang greatly reduces effective clamping torque.

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.
