China High Voltage Switchgear Retainer Ring Manufacturer, Supplier, Factory

SOLH HRQ dual piston rack & pinion rotary cylinder includes micro sizes HRQ2/3/7 and medium-to-large HRQ10~HRQ200 with infinitely adjustable swing angle 0~190°. It outputs higher torque and stronger bending/radial load capacity than vane rotary actuators. Three configurations are available: basic mechanical stop buffer (low-cost for light low-speed duty), -A integrated hydraulic shock absorber (high-speed heavy load precise stopping), and -A(S) hydraulic version with stainless steel end caps for humid & slightly corrosive environments. The rotary table features central hollow through hole for tubing and wiring, and side sensor slots compatible with universal magnetic reed switches. Micro models adopt bottom mounting holes while medium/large sizes provide multi-side mounting taps for flexible layout. Pre-filled long-life grease enables lubrication-free operation. Selection requires simultaneous verification of torque, radial/axial load and bending moment. Widely used for rotary indexing in automatic assembly, material sorting, packaging capping and jig turnover stations.

SOLH ARM5S ultra-compact miniature pressure regulator features a 14mm ultra-narrow piston structure and ultra-light 33g weight, greatly saving installation space. Equipped with standard reverse flow function and optional relief/non-relief structure, it comes with integrated one-touch push-in fittings for versatile tubing connection. Supporting direct panel mounting and DIN rail manifold stacking installation with 0.05–0.7MPa adjustable pressure range, it realizes lubrication-free and corrosion-resistant stable operation. It is an ideal micro pneumatic control solution for precision automation, miniature jigs and space-limited equipment.

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.
