China KQ2VD 1 to 2 vertical air splitter Manufacturer, Supplier, Factory

SOLH CU/CDU rectangular free mount cylinder features ultra-thin block structure with multi-surface mounting holes, enabling multi-angle direct installation without brackets to save equipment space. Complete variants include non-magnetic CU, magnet-equipped CDU, CDUK non-rotating rod and CDUW double guided rod models. Bore sizes φ6~32mm, available in single/double acting types with fixed rubber buffers on both ends for continuous oil-free operation. CDU series is compatible with CMSH and DMSH magnetic switches for position detection and tolerates partial side load. Widely used in 3C & semiconductor jigs, automation stoppers, light clamping positioning and small press-fit mechanisms for compact automated equipment.

A Switchgear Drawer Microswitch is a vital component in the operation and safety of electrical switchgear systems. Designed for precision and reliability, this microswitch is typically installed within the switchgear drawer mechanism to detect and signal the position of the drawer—whether it is fully inserted, withdrawn, or in an intermediate position. The microswitch operates by actuating when the drawer moves, sending an electrical signal that can control various interlocking and safety functions.

SOLH 4A series 5/2-way and 5/3-way air-operated directional control valves are the full pneumatic counterpart of the classic 4V electromagnetic solenoid valve series. Driven entirely by external pneumatic control signals with no coils or electrical parts inside, this valve achieves inherent explosion-proof safety and serves as the core control unit for non-electric pneumatic loops, hazardous explosive areas and safety interlock systems. It adopts high-precision spool configuration and robust aluminum alloy housings, sharing identical installation dimensions and flow characteristics with the 4V series for seamless direct replacement and upgrade between electric-driven and full-pneumatic control schemes. The standard five-port layout follows industry universal specifications: P for main air supply inlet, A and B as working ports connected to two chambers of double-acting cylinders for extension and retraction regulation, R and S as exhaust ports compatible with standard silencers to reduce operational noise. The 5/2-way lineup supplies single pneumatic control and double pneumatic control options. Single air-controlled models switch upon receiving control air signals and automatically reset by built-in springs once the control pressure disappears to deliver fail-safe protection. Double air-controlled variants feature no return springs and lock the current spool position persistently after control air is disconnected, supporting long-duration positioning and pressure retention without sustained control air input. 5/3-way versions are exclusively double air-driven with three selectable neutral configurations: closed center (Type C) seals all ports to lock cylinders and prevent vertical falling; exhaust center (Type E) vents A/B ports to atmosphere for pressure release and manual commissioning; pressure center (Type P) feeds compressed air to both working ports for synchronous clamping and force balance adjustment. Suitable for filtered compressed air within 0.15~0.8 MPa working pressure, the whole series supports lubrication-free operation and works reliably from -20℃ to +70℃. Widely applied in chemical plants, painting workshops, mining and other explosion-risk environments, it cooperates with mechanical valves, hand-operated valves and air pilot valves to build complete all-pneumatic logic control systems for double-acting cylinders.

Models AC2010–AC5010 with Rc1/4"‑1" ports, ideal for compressor rear‑end air purification and pressure stabilization.

SOLIH ZL212 multi stage vacuum ejector, drop in upgrade for ZL112 with SMC compatible mounting dimension. Higher vacuum 90~-95 kPa and +30% suction flow, 40% energy saving via multi venturi design. Modular options: silencer/port exhaust, mechanical gauge or digital vacuum pressure switch (NPN/PNP), supply+release valve. Ideal for glass, sheet metal, porous material and high leakage large suction cup robot handling.

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.
