SOLH MQR multi-channel rotary union adopts metal non-contact gap sealing with ultra-low rotating torque of 0.003~0.50 N·m. Free of rubber sealing rings, it avoids sticking even after long static storage. Available with 1/2/4/8/12/16 independent air passages without cross-leakage, it works under -100kPa vacuum to 1.0MPa positive pressure. Supported by double bearings, it reaches max 3000 rpm bidirectional rotation with up to 1 billion maintenance-free rotations. Equipped with standard M5 thread ports and lubrication-free structure, it eliminates pipeline twisting for robot joints, rotary indexing tables and rotary cylinders, widely applied in rotary jig vacuum adsorption and continuous air supply for electronics, packaging & printing rotating automation machinery. The stationary housing should be fixed and the rotating side matched with flexible coupling; heavy radial and axial loads are prohibited.

SOLH MG series stainless steel mini pneumatic cylinders are engineered in compliance with JIS industrial standards, offering cost-effective alternatives to SMC CM2 & CM3 series with full dimensional interchangeability for direct replacement and production line retrofitting. Constructed with SUS304 stainless steel barrel and piston rod paired with high-strength aluminum end caps, they deliver outstanding rust resistance against high humidity, dust, weak acid and weak alkali surroundings, perfectly suited for food, pharmaceutical and packaging automation. Rivet rolling crimping secures the barrel and end caps tightly for excellent anti-vibration stability during long-term high-frequency reciprocation. A complete lineup covers standard double-acting, spring single-acting power-off reset types, synchronous double-rod variants and upgraded models with manually adjustable air cushions to suppress impact and noise in high-speed cycles. Low-friction composite sealing with built-in oil storage grooves supports oil-free maintenance-free operation for over 8 million working cycles. Every unit comes pre-installed with a built-in magnetic ring compatible with SMC M9B and Airtac CS1-G sensors to realize real-time position feedback and PLC automated linkage control. Supported by steady mass production and adequate overseas spot inventory, these cost-efficient cylinders are widely deployed in medium-grade automated equipment operating in damp and mildly corrosive workshop environments.

Richge is a manufacturer of Ground switch interlock devicein China, specializing in precision-engineered solutions designed to ensure safe and reliable operation of ground switches within switchgear systems. Our interlock mechanisms are essential for enhancing operational safety by preventing unauthorized or incorrect switching actions.

SOLH MSZ three-position rack-and-pinion pneumatic rotary cylinders are dedicated rotary actuators engineered to achieve three-point locking positioning (left limit / intermediate stop / right limit), solving the limitation of conventional two-position rotary cylinders lacking mid-station positioning. This series only needs one 5/3-way center-pressure solenoid valve for full position switching, removing complicated dual-valve pneumatic circuits to simplify system layout and lower overall engineering costs. The intermediate locking position supports ±10° fine angular adjustment, while the left and right travel limits are separately tunable within 0~95°, delivering flexible multi-angle positioning. It is classified into four specifications: basic MSZB, high-precision MSZA, rubber buffer MSZB-R and hydraulic buffer MSZA-R. The dual-rack dual-piston internal structure effectively eliminates gear backlash and outputs steady torque during frequent position switching. The integrated rotary plate comes with reserved locating pin holes for direct workpiece installation, paired with a central hollow through-hole to pass wiring and air tubing neatly. Standard side sensor grooves fit D-M9B & D-A93 magnetic switches to realize real-time signal feedback of three working stations. MSZA boasts positioning accuracy up to ±0.02 mm, while hydraulic buffer variants absorb large collision energy perfectly for high-speed heavy-duty rotation. Adopting oil-free self-lubricating design for long-term stable running, this rotary cylinder is widely deployed in workpiece sorting diversion, multi-station indexing, electronic positioning inspection and packaging automated steering flip procedures.

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.
