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.

SOLH RM series magnetic coupling rodless cylinder is designed to be interchangeable with Airtac counterparts. It adopts non-contact magnetic synchronous drive and fully enclosed barrel structure for zero leakage and dust-free operation, suitable for oil-free clean environments of electronics, medical and food industries. Bore sizes range from φ10 to φ40 mm with maximum stroke of 2000 mm, operating within a wide industrial temperature range of -20℃~70℃ and featuring a minimum startup pressure of 0.15 MPa. Four structural variants are available: RMS basic type without built-in guides requiring external rails and end brackets with the lowest cost; RMT standard type integrated with dual guide rods and sliding bearings to resist ordinary lateral loads without extra guides for easy installation; RMTL precision version with extended high-precision guide rods achieving ±0.1mm repetitive positioning accuracy; RMH heavy-duty reinforced slide type with strong anti-deflection capacity for independent load bearing. Standard dual-end rubber buffers are equipped, with optional adjustable buffers and external hydraulic buffers for stable movement up to 500 mm/s. Optional magnetic switch kits match D-M9 sensors for position signal feedback. Built-in guiding structures cut extra procurement and assembly costs of external linear guides. It delivers outstanding cost performance versus SMC CY1 and CY3 series, widely used in long-distance material conveying, protective door actuation and space-saving retrofitting of conventional tie rod cylinders on medium-budget automated production lines.

Switchgear Spring Blade – Product Details and Application Introduction The Switchgear Spring Blade is an essential component used in medium and low-voltage switchgear systems, designed to provide reliable contact pressure and ensure smooth electrical connectivity between conductive parts. These spring blades are typically made from high-quality materials such as stainless steel, copper alloys, or beryllium copper to offer both high electrical conductivity and corrosion resistance. Their design ensures longevity even under harsh environmental conditions and frequent mechanical stress.

SOLH CRBU2 ultra-thin free-mount vane rotary actuator is fully interchangeable with equivalent SMC models, available in bore sizes 10/15/20/30/40. Integrated cylindrical body enables bracket-free multi-directional fixing, 12% lighter than CRB2 series, perfect for concealed installation inside compact integrated machinery. Direct vane drive eliminates gear backlash with ultra-high angular repeatability of ±0.01°. Two vane variants: S single vane for max 270° swing, D double vane delivering double torque with limited 90°/100° rotation. Dual piping layouts are offered: standard side ports and suffix-E central axial ports. Optional suffix-W angle adjuster realizes infinitely adjustable stroke from 0 to 240°, and built-in magnetic rings support M9BW reed switches for PLC limit feedback. Low-friction composite sealing ensures oil-free operation with over 5 million service cycles. Widely applied to light-load high-frequency precision rotation tasks including 3C miniature jig turnover, vision camera positioning, screw tightening mechanisms and small-angle packaging switching. Compared with base-mounted CRB2 rotary cylinders, CRBU2 requires no mounting brackets and maximizes space efficiency, ideal for robot end effectors and narrow internal equipment layouts.
