SOLH HLH ultra-thin side L rail linear slide cylinder adopts integrated single-side recirculating ball guide rail with slim low-profile body to save installation space, a double-acting pneumatic slide dedicated to light-load precision positioning. Bore sizes range from 6, 10, 16 to 20 mm with standard strokes of 5–60 mm, operating pressure 0.15~0.7 MPa and working temperature from -20℃ to 70℃. The cylinder body features 4-direction mounting tapped holes and 3-side air ports for flexible piping layout. The slide carriage is equipped with fixture tapped holes and positioning pin holes on top and front surfaces. A built-in magnetic ring comes as standard, with dual side slots for mounting magnetic reed switches. The floating joint between piston rod and carriage eliminates lateral side load and ensures excellent straightness & anti-rotation precision. Compared with twin-rail HLQ series, HLH features slimmer outline for confined narrow space, widely applied in 3C & semiconductor mini inspection jigs, light-duty push-clamping units and reciprocating positioning mechanisms inside compact automation machinery.

Application of IndoorsF6 Circuit Breaker SF6 circuit breakers are a perfect upgrade foraging power infrastructure,especially in situations where the insulation of motors and cables is sensitive to dielectric stress.Indoor SF6 circuit breakers.with their compact footprint and top-notch insulation performance,are right at home in space-constrained indoor substations and distribution rooms.They stand up well to frequent operation,ensuring the stable running of critical equipment and slashing maintenance downtime.Furthermore,their environmentally friendly characteristics make them an ideal fit for indoor locations with strict environmental requirements,helping to build a safer and more reliable power distribution network. LYHM4 medium voltage circuit breaker uses sulfur hexafluoride (SF6) gas as arc extinguishing and insulating medium. SF6 gas has smooth breaking characteristics, and there will be no interception phenomenon when breaking the current, and no operating overvoltage will occur. This excellent characteristic ensures that the circuit breaker has a long electrical life. And the impact on the equipment during operation, the dielectric level and thermal stress will not be affected.

SOLH 4H series hand lever directional control valves are developed in accordance with mainstream industrial standards, covering 5/2-position and 5/3-position configurations. Operated purely by manual lever manipulation without electromagnetic coils or pneumatic pilot signals, these spool-type manual valves are widely adopted for on-site equipment commissioning, emergency safety shutdown and inching control of double-acting cylinders. Constructed with high-strength aluminum alloy housings and precision spool assemblies, two positioning structures are optional: automatic spring return and steel ball mechanical locking. Crucially, the mounting dimensions are fully consistent with 4V solenoid valves and 4A air-operated valves, enabling direct interchange and flexible switching among electric, pneumatic and manual control modes in standard pneumatic systems. The five-port layout complies with international general specifications: P serves as the main compressed air supply inlet; Ports A and B connect to two cavities of double-acting cylinders to govern extension and retraction movements; R and S are exhaust ports compatible with standard silencers to lower exhaust noise. For 5/2-position models, spring-reset variants automatically rebound once the lever is released to deliver foolproof protection against unintended continuous actions; self-locking versions secure the spool position via steel ball positioning and stay latched until manual switching, ideal for long-duration fixed working states. All 5/3-position units adopt dual stable ball positioning with three configurable neutral modes. Closed Center (Type C) seals all ports to lock cylinders and prevent falling of vertically mounted actuators; Exhaust Center (Type C) vents A/B ports for pressure relief, allowing free cylinder floating during manual testing; Pressure Center (Type P) supplies compressed air to both working ports for synchronous clamping and force balance regulation. Running on filtered compressed air within 0.15~0.8 MPa under lubrication-free conditions, the valves work steadily at -20℃ to +70℃. Available specifications range from 4H200 to 4H400 with multiple thread options. Devoid of electrical components, the valves feature spark-free inherent explosion resistance, well-suited for flammable, dusty and high-risk production sites. They support panel mounting and base installation, frequently applied for production line manual commissioning, emergency pneumatic circuit cut-off, safety interlock loops and retrofitting replacement of automatic control valves.
