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.

SOLH ZL112 multi-stage venturi vacuum ejector is fully interchangeable with equivalent SMC models, equipped with standard Φ1.2 nozzle. Its energy-saving multi-stage structure delivers stable vacuum of -88~-92kPa while cutting air consumption by over 40% versus single-stage ejectors. Adopting a highly integrated modular design, it offers K1 dual supply/release valves for auto suction & blow-off and cost-saving K2 single supply valve variants. The built-in silencer restricts operating noise below 70dB(A); two exhaust styles are available: standard integrated muffler type and P centralized port exhaust for high flow. Optional accessories include analog mechanical vacuum gauges and digital vacuum pressure switches with NPN/PNP single/dual channel and voltage/current analog signal outputs, plus diverse plug connectors, coil voltages and manual adjustment knobs. Free of internal moving parts for maintenance-free continuous operation, it can be mounted directly on robot end effectors to shorten vacuum response time, widely applied to multi-suction cup handling of 3C glass panels, sheet metal, packaging & printing materials and porous workpieces requiring stable high-flow vacuum adsorption.

GN19-12(C) indoor HV disconnect switch applies to power system of rated voltage 12kV, AC 50/60Hz. It is equipped with CS6-1 manual-operating mechanism and is used to break and make circuit under no-load. There are additional pollution type, high-altitude type and power indicating type. It is made as per IEC 62271-102. The isolating switch of this series is equipped with a CS6-1 manual operating mechanism (the isolating switch with a panel has its own conjoined operating mechanism).   This series of isolating switches is a three-pole type, which consists of a chassis, a rotating shaft, a lever, a porcelain pillar insulator, a knife and a wiring board. The rotating shaft is arranged on the bottom frame, on which three pairs of levers are welded, and the levers pass through the pull rod porcelain insulator and the knife necklace. The rotating shaft extends out of the base frame, and any section of the rotating shaft can be connected with the operating mechanism.   Type C is through the wall. Among them, C1 means that the rotation is on the side through the wall; C2 means that the disconnection is on the side through the wall; C3 means that both sides are on the side through the wall.
