China Low-voltage Switchgear Assembly Insulation Clamp Assembly Manufacturer, Supplier, Factory

SOLH AMC series exhaust cleaner is a 2-in-1 unit integrating oil mist separation and silencer function, engineered as a drop-in alternative to SMC AMC. It captures fine oil mist and dust from cylinder and solenoid valve exhaust while cutting noise by 30–35dB. Featuring centrifugal pre-separation, replaceable glass fiber + activated carbon element and built-in oil sump, it keeps clean workshops oil-free. Available in R, NPT and G thread with bracket and drain piping versions.

SOLH 3A series 3/2-way externally air-operated directional control valves are manufactured in accordance with mainstream industry standards. Driven entirely by pneumatic signal input without any electromagnetic coils, this series is engineered to govern extension, retraction and pressure retention of single-acting pneumatic cylinders. It serves as the critical safety control element for all-electric-free pneumatic circuits, hazardous explosive atmospheres and fail-safe industrial machinery. The standard three-port layout follows universal industrial definitions: P for main compressed air supply inlet, A for working outlet connected directly to single-acting cylinders, and R for exhaust port for pressure relief and rapid spring reset. Two control configurations are available. Single pneumatic control models (3A×10) switch upon receiving external air signals and automatically reset via built-in springs once the control air signal is removed to guarantee fail-safe reset performance. Double pneumatic control variants (3A×20) adopt latching spool structure, locking the valve position persistently even after control air is disconnected to sustain long-term clamping and positioning. Constructed with high-strength aluminum alloy valve bodies and precision-machined spools, the valves support oil-free operation under filtered compressed air with filtration precision above 40 μm within the working pressure range of 0.15~0.8 MPa. Four dimensional specifications from miniature 3A100 up to heavy-duty high-flow 3A400 cover M5 to G1/2 thread connections, and NPT threads are optional for overseas projects. Without internal electrical parts, the valve features intrinsic explosion-proof performance, perfectly suited for flammable, dusty and humid working environments. It supports random multi-angle installation and manifold assembly for modular valve banks, widely deployed in workpiece clamping mechanisms, pneumatic safety interlock systems and long-duration positioning stations.

Product Introduction: Switchgear Adaptor The Switchgear Adaptor is a crucial component designed to enhance the flexibility and interoperability of electrical switchgear systems. Engineered to connect different switchgear units seamlessly, this adaptor ensures reliable and safe operation across various configurations. It is constructed from high-quality materials, such as robust stainless steel and durable plastics, which provide excellent resistance to corrosion and wear, ensuring longevity even in demanding environments.

SOLH ASC series one-way exhaust throttle valve, AirTAC standard aluminum alloy in-line pneumatic flow control valve. Thread-type without push-fit joint, lock anti-vibration adjustment nut, exhaust throttling for double-acting cylinder speed regulation. Models ASC100-06, ASC200-08, ASC300-10, ASC300-15 with PT/G/NPT thread options, ideal for general-purpose automated pneumatic circuits.

SOLH RSQ fixed-height pneumatic stopper cylinders serve as standard limit actuators for automated conveyor systems. Equipped with ten interchangeable rod ends including hydraulic buffer lever styles for heavy shock absorption, they support four-side magnetic switch fitting and oil-free long-cycle operation. Differing from height-adjustable RSG models, its fixed rigid frame cuts on-site debugging time greatly. Our stable mass production ensures sufficient spot stock; these stoppers are widely deployed on electronics assembly lines, roller conveyors and heavy pallet positioning stations globally, delivering reliable workpiece blocking with affordable cost and strong impact resistance.

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.
