China VX23 direct acting 2 way solenoid valve Manufacturer, Supplier, Factory

SOLH 3V series 3/2-way pneumatic solenoid directional control valves are engineered with both direct-acting and pilot-operated structures, tailor-made for driving single-acting spring return cylinders and switching vacuum pneumatic circuits. Available in Normally Closed (NC) and Normally Open (NO) configurations, this series adopts high-strength lightweight aluminum alloy valve bodies with compact layout, rapid response and IP65 dustproof & waterproof protection grade, acting as the standard core control component for small and medium-sized pneumatic automation systems. The port layout follows universal industry standards: P for main air inlet, A for execution working port connecting cylinders or vacuum suckers, R for exhaust port matched with silencers to lower operational noise. Direct-acting 3V1 and 3V2 variants support reliable zero-pressure startup within 0~0.8 MPa with switching response under 0.05s, perfectly fit for low-pressure gas pipelines and negative-pressure vacuum control scenarios. Pilot-operated 3V100/3V200/3V300 series features larger flow capacity and lower coil power consumption, requiring a minimum inlet pressure of 0.15 MPa for stable switching to satisfy high-flow conventional pneumatic loops. Equipped with a thimble-style manual override button for convenient on-site debugging during installation and maintenance, the whole series supports oil-free operation with stable sealing performance. Multiple thread specifications including M5, G1/8, G1/4 and G3/8 are optional, paired with mainstream global AC & DC voltages and two wiring modes of DIN socket and flying leads. It can directly replace traditional 3A air pilot valves and 3L hand pull valves without structural modification, widely deployed in workpiece clamping jacking mechanisms, vacuum adsorption switching, pneumatic interlock protection and inching control of small actuators.

SOLH CRQ2 ultra-thin rack and pinion rotary cylinders adopt double-rack meshing structure to achieve zero-backlash precise rotation, perfectly suited for space-constrained light & medium-duty automation. Featuring ultra-low-profile flat integrated flange construction without extra mounting brackets, it supports 90°, 180° and optional 360° full-circle rotation with ±5° fine angle calibration. Bore sizes range from φ10 to φ40; larger specifications are available with adjustable air cushions to cushion inertial impact during frequent cycling. The CDRQ2 magnetic version supports magnetic switch installation for PLC position signal linkage. Oil-free self-lubricating design cuts maintenance workload greatly. Supported by stable mass production and sufficient spot stock, these compact swing actuators are widely deployed in 3C electronics PCB flipping, packaging machinery, medical automation and precision miniature indexing stations.

Product Details and Application of Switchgear Base Ball Bearing Guide Rail The Switchgear Base Ball Bearing Guide Rail is a critical component designed for enhancing the operational efficiency and reliability of electrical switchgear systems. Constructed from high-strength, corrosion-resistant materials, this guide rail ensures durability and longevity in various environments.

SOLH MD multi-position free-mount compact cylinder is equipped with tapped mounting holes on six sides of the block body for bracket-free installation at any angle, 30%~50% thinner than standard round cylinders to fit narrow, high-density equipment layout. Five sub-models cover all working modes: standard single-rod double acting MD, single-rod single acting MSD (spring extend) / MTD (spring retract), anti-torsion double-rod MDD, and stroke-adjustable double-rod MDJ. Bore sizes range from 6 to 32 mm with standard strokes 5~60 mm. Each unit comes with built-in front rubber buffer and dual side slots for magnetic sensors; suffix-S stands for integrated permanent magnet compatible with CMSH/DMSH reed switches. The piston rod adopts integrated self-lubricating bushing for oil-free smooth operation. Double-rod variants eliminate lateral deflection from offset loads, while MDJ features rear adjustment screw for flexible stroke fine-tuning. Widely applied to light-duty clamping, ejecting, crimping and precise positioning of miniature jigs in 3C, semiconductor and general small automation machinery.

SOLH CRB1 / CRB2 vane-type rotary actuators are fully interchangeable with equivalent SMC swing cylinders. Direct vane drive eliminates gear backlash, delivering low rotary inertia and ultra-fast response. CRB2 is the compact light-duty range with bore sizes 10~40 mm; single vane supports up to 270° swing while double vane limits rotation to 90°/100°, ideal for high-speed mini flipping in confined-space 3C and packaging equipment. CRB1 heavy-duty series covers 50~100 mm bores with full bearing support and outstanding impact resistance, providing maximum torque up to 24 N·m for heavy fixture and large workpiece indexing turnover. Single vane offers wide swing range, whereas double vane doubles torque at the same bore size. Built-in rubber bumpers come standard; angle adjuster suffix Z and hollow shaft are optional, and CDRB variants integrate permanent magnets compatible with D-M9B / D-A93 reed switches. Compared with MSQ rack-and-pinion rotary tables, vane-type cylinders feature slimmer body and faster rotation with zero backlash yet weaker radial & axial load capacity, making them the top choice for high-speed light-load rotary tasks requiring large swing angles.

SOLH MGJ ultra-compact mini guide rod cylinder is fully interchangeable with SMC standard products, developed exclusively for miniature automation. It only supplies two tiny bore sizes φ6 mm and φ10 mm with ultra-short strokes from 5 mm to 20 mm. Built-in dual guide rods and integrated guide frame deliver ultra-precise anti-rotation performance within ±0.1°, preventing angular displacement during clamping and assembling micro components. Extremely lightweight structure weighs merely 27.3 g for MGJ6-5 model. Dual mounting surfaces (bottom & rear side) and single-side centralized piping & wiring facilitate neat layout for dense multi-cylinder arrangement. Adopting oil-free maintenance-free structure with dual-end rubber buffers, it supports stable high-frequency reciprocation within -10℃~60℃. Widely applied in precision electronic component clamping, PCB positioning, miniature valve actuation of medical devices, sampling needle lifting, micro displacement adjustment in semiconductor clean workshops and fine tuning of optical lenses. Compared with standard MGP compact cylinders, it features drastically reduced overall dimension, perfectly satisfying micro thrust, limited installation space and high-precision anti-rotation positioning demands of miniature automation.
