China SOLH C85 ISO6432 miniature stainless steel pneumatic cylinder Manufacturer, Supplier, Factory

The VSG-12 indoor high-voltage vacuum circuit breaker is designed for use in indoor switchgear applications within 12kV power systems with a three-phase AC 50Hz rated voltage. It serves as a crucial protective and control unit for power distribution equipment and industrial facilities. This circuit breaker is suitable for environments that require frequent operations at the rated current or the capability to interrupt short-circuit currents multiple times. The circuit breaker features a modular design, where the operating mechanism and the circuit breaker body are separable, allowing for quick replacements and assembly. VSG vacuum circuit breaker is a new indoor switchgear. It is mainly used for three-phase AC power system with rated voltage of 12kV and rated frequency of 50-60HZ. It has the advantages of compact structure, high reliability, small operation vibration and easy maintenance. It can be widely used in power plants, steel mills, metallurgy, petrochemical, transportation, buildings and other industrial and mining enterprises. As a switchgear for protecting high-voltage motors, transformers, line faults and other loads.

SOLH M5 series 5/2-way spring return mechanical directional valves adopt unified M5×0.8 fine thread interfaces across the whole product lineup. These coil-free pneumatic valves switch air channels relying purely on external mechanical actuation force and automatically reset by built-in springs once external force is removed. They serve as core miniature pneumatic signal trigger components widely deployed for cylinder stroke limit positioning, in-position feedback signal transmission and local manual pneumatic switching on automated equipment. The complete series covers two major categories: mechanically actuated types (plunger, roller lever, unidirectional roller) and manually operated types (pushbutton, toggle lever, mushroom emergency button, rotary lock button), fully dimensionally interchangeable with mainstream AirTAC M5 series mechanical valves for direct drop-in replacement. The standard five-port layout consists of P main air supply inlet, A/B working ports connected to miniature double-acting cylinders, and two separate side exhaust ports R1/R2 reserved for miniature silencer installation to cut exhaust noise and block external dust ingress. A balanced sliding spool structure is adopted, which is immune to air supply backpressure interference; only light external force is required to complete stable valve switching with ultra-sensitive response. Multiple actuation heads are optional to fit diverse working conditions: M5B straight plunger for rigid contact positioning detection, M5R universal roller lever triggered by cams and baffles, unidirectional roller M5L for single-direction limit anti-misoperation, and various manual button & toggle styles for on-site manual jog control and emergency cut-off. Constructed with hard anodized aluminum valve bodies and wear-resistant NBR nitrile rubber seals, the valves support lubrication-free operation under filtered compressed air within 0.05~0.8 MPa, boasting a service life exceeding 10 million switching cycles. Custom multi-station manifold bases (M5M series) are available for centralized air feeding and modular integrated installation, together with matching adapters, micro silencers and quick connectors. Distinguished from 3/2-way S3 pilot valves, this 5-port M5 series can directly drive small double-acting cylinders or output pilot signals to actuate main solenoid valves. Typical scenarios include assembly fixture in-place detection, cylinder travel automatic reversing, on-site manual debugging and small automation pneumatic logic signal triggering.

SOLH CDUJB ultra-compact free mount cylinder is developed for equipment with limited installation space. Compared with conventional CU series, its length is reduced by 64% and volume cut by 70%. The square compact body supports multi-surface direct mounting without extra brackets. The product lineup includes non-magnetic CUJB, magnet-equipped CDUJB and copper-free cleanroom CDUJS. Bore sizes range φ4~20mm, available in double acting and single acting spring return types with optional rubber cushion. Magnetized models match miniature magnetic switches for short-stroke precise motion and support oil-free operation. Widely applied in 3C electronics, semiconductor wafer positioning and medical clean automation. Magnetic shield plates are optional for densely arranged cylinders.

Manual withdrawal switchgear The production process and main functions of Manual withdrawal switchgear: The accessories produced by Richge company are according to the design drawings, the steel plate or stainless steel plate is cut according to the size, and the stamping process, the formation of various panels and holes. According to customer needs, application scenarios and technical specifications, determine the functional configuration, structural form and electrical parameters of the switch cabinet accessories A hand pull mechanism in a switch cabinet is a system in which an operator manually pulls out or inserts electrical components. Ensure that the operator can remove or insert the component safely and efficiently.

SOLIH AC series FRL three‑unit combo integrates AF 5μm air filter, AR pressure regulator and AL lubricator in one modular assembly. Max 1.0 MPa, 0.05–0.85 MPa adjustable pressure, manual/auto drain optional, self‑locking regulator knob, transparent oil/water cups with protective covers. Models AC2000–AC5000 with Rc1/4"‑3/4" ports, ideal for compressor rear‑end clean, stable and lubricated air supply for industrial cylinders and pneumatic actuators.

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.
