China C/E/P middle function hand valve Manufacturer, Supplier, Factory

SOLH VR3200/VR3201 power-free mechanical pneumatic-electric relay is fully interchangeable with matching SMC models. It converts air pressure signals into 1NO+1NC dry contact signals without external power supply for PLC interlock, pressure monitoring and fault alarm, with adjustable trigger pressure ranging from 0.1 to 1.0MPa and high-load built-in micro switch. Three variants are available: open-frame VR3200 for dry dust-free control cabinets; fully sealed IP44 drip-proof VR3201 for humid & dusty machine tools and production lines; CE-certified VR3202 with dedicated grounding terminal for strong EMC interference and export machinery. Equipped with standard Rc1/8 air inlet, brass valve body, POM piston, stainless steel return spring and NBR seal, it is widely used for cylinder clamping pressure confirmation, vacuum chuck negative pressure feedback, main air source low-pressure warning and signal conversion in explosion-prone workshops without electronic sensors.

SOLH MSQ rack-and-pinion rotary actuator is fully interchangeable with equivalent SMC rotary tables. Driven by symmetrical dual piston gear rack structure, it generates 3~4 times higher torque and superior radial & axial load capacity versus vane-type CRQ cylinders. Two grades are available: MSQB standard series with H9 tolerance and MSQA high-precision series featuring H8 fit and ±0.01mm repeat positioning accuracy. The rotary table is pre-machined with locating pin holes and fixture tapping holes, plus a central hollow through hole for wiring & tubing routing. Equipped with dual-end angle adjustment screws for infinitely adjustable swing range 0~190°, fixed 90°/180° swing variants are optional. Two damping solutions are offered: standard rubber bumpers and suffix-R integrated hydraulic shock absorbers (L low kinetic energy / H high kinetic energy). Dual piping layouts include default end-face ports and E side front ports. Built-in magnetic rings support M9BW reed switches to transmit position feedback signals to PLC. Frame sizes range from 10 to 200, pre-filled with long-life grease for lubrication-free operation. Widely applied to PCB optical inspection, microchip precision positioning, packaging direction switching, machine tool workpiece flipping and mini manipulator end rotary joints for indexing, turnover and multi-angle positioning automation.

The Switchgear Locking Pin is a crucial component designed to ensure the secure operation and maintenance of electrical switchgear systems. Crafted from high-grade stainless steel or durable alloy materials, these locking pins offer exceptional strength and resistance to wear and corrosion. Their precision-engineered design features a robust locking mechanism that provides a reliable and secure fit, preventing accidental disengagement during operation.
