China Vacuum Circuit Breaker (VCB) Manufacturer, Supplier, Factory

SOLH CQ2 square compact thin cylinder is fully interchangeable with SMC CQ2 series. Its ultra-short square body reduces length by 50% compared with conventional tie rod cylinders to save installation space. It covers a complete bore range φ4~200mm with abundant variants: single rod, CQ2W twin rod, CQ2K non-rotating piston rod, optional air cushion and ultra-short stroke version. CDQ2 models with built-in magnet support multi-side magnetic switch mounting without protruding sensors. Standard rubber bumpers are equipped, and air cushion is optional for high-speed operation. Adopting oil-reserved low friction seal for oil-free operation with service life up to 5 million cycles, widely used for clamping, pushing and positioning in electronics, automotive and packaging automation.

SOLH VCH400 (VCH410) series pilot operated 3-port poppet solenoid valve is customized for medium & high-pressure gas pipelines with max operating pressure up to 5.0MPa. Equipped with high-pressure polyurethane elastic seals and large-size ISO G threads (G1/2, G3/4, G1), it delivers high flow capacity and ≤±2ms response deviation, with outstanding vibration & shock resistance and 10-million-cycle service life. Drip-proof structure reaches equivalent IP65 protection; the NC version automatically vents upon power loss, ideal for high-pressure charging, venting and pressure conversion circuits, and perfectly matched with SOLH VCHR high-pressure regulators. Only applicable to clean dry compressed air and inert gas. Coil-down mounting is prohibited, and periodic cycling actuation is required to avoid poppet adhesion. It serves as reliable control component for industrial high-pressure air charge & vent equipment.

SOLH SAI tie-rod-free profile cylinder complies with ISO15552 standard, dimensionally interchangeable with FESTO DNC and SE series. Adopting M-shaped integrated aluminum barrel, it is fitted with double-end adjustable air cushion & PPV elastic pad and dual-side sensor grooves. Full variants include single rod, double rod, stroke adjustable, lockable and SAIF valve-integrated cylinder. It supports oil-free operation with low starting pressure. Bore sizes φ32~200mm, customized stroke up to 2000mm, and various ISO mounting options. Widely used in packaging machinery, conveyors and machine tool automation. Stable mass production and sufficient stock make it a cost-effective general linear actuator for export automation equipment.

SOLH HLQ / HLQL twin-shaft slide cylinders adopt recirculating ball linear guides, including HLQ compact standard version with side-mounted cylinder and ultra-rigid symmetrical HLQL model. Bore sizes range from 6 to 25 mm with strokes 10–150 mm. The twin parallel piston rod design delivers strong thrust and excellent anti-torsion & anti-rotation performance. A built-in floating joint between piston and slide carriage offsets eccentric lateral loads. The base features 3-direction mounting tapped holes, while the slide carriage provides multi-surface fixture mounting holes and positioning pins; side slots for magnetic reed switches and built-in magnet come as standard. Multiple buffer options are available: double / single adjustable air buffer, hydraulic shock absorber and external stop blocks for smooth reciprocation and high repeat positioning accuracy. HLQ fits medium-small loads with limited space, while symmetrical HLQL handles heavy loads and severe eccentric offset. Widely used for automatic transfer, precision clamping and linear positioning in 3C, semiconductor assembly and testing equipment.
