The Switchgear Guide Rail is a crucial component in electrical switchgear systems, designed to ensure the smooth and reliable operation of various switchgear parts. Constructed from high-strength, corrosion-resistant materials such as stainless steel or galvanized steel, these guide rails provide exceptional durability and stability under demanding conditions.

SOLH IR series precision pilot regulators adopt advanced nozzle-flapper internal pilot structure, delivering 0.2% ultra-high control accuracy and excellent repeatability. It stably maintains output pressure against air source fluctuation and dynamic load changes. Featuring high flow rate, fast response and ultra-low air consumption of 1–3 L/min for significant energy savings, it supports manual adjustment and pneumatic remote control. Compact and flexible with built-in overpressure protection, it is widely used in semiconductors, precision testing, tension control, medical instruments and high-end precision automation systems.

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.

FLN48-12 load break switch use SF6 gas as arc extinguishing and insulating medium. There are three work stations: opening, closing and grounding in the switch. It has small volume, installing easy-to -use, strong environmental adaptabiliy and other characterist.. It is also for the control and protection of substation and equipments; making and breaking short-circuit current under various operating status of electric network and its performance indicators meet the national standard GB/T3804-2017 "3.6kV-40.5kV high-voltage AC load switch", which is the main switching element of the ring main unit.
