China Box Hinges and Latches for Electrical Enclosures - Stainless Steel Switchgear Door Hinge for Control Distribution Cases and Network Cabinets Manufacturer, Supplier, Factory

SOLH SY series pilot-operated 5-port solenoid valve is fully interchangeable with matching SMC valves, including SY3000 mini, SY5000 medium mainstream, SY7000 large and SY9000 extra-large models. It provides complete circuit options: 5/2 single/double coil and 5/3 three-position with center closed, center exhaust & center pressure supply functions. Standard 0.35W coils and optional 0.1W ultra-low power energy-saving coils generate little heat for continuous energization. Internal pilot version works 0.1~0.7 MPa, while external pilot variant supports -100kPa vacuum environment. The gap-sealed spool reaches up to 200 million switching cycles. Air ports are arranged on side, top and bottom for flexible tubing routing. Valves adopt plug-in snap design compatible with SS5Y manifold valve islands, enabling single-valve maintenance without disassembling the whole bank, with IP65 plug connector and IP67 manifold base rating. Optimized internal runners deliver around 80% higher flow than legacy valves, and built-in pilot filter mesh prevents spool stuck by dust. Widely used for cylinder directional switching and centralized pneumatic control in semiconductor, automotive welding, packaging and medical automation equipment.

Their compact dimensions and limited weights make the Power Cube type PB/F fixed parts the ideal solution for replacing fixed circuit breakers with withdrawabie circuit breakers, for retrofitting activities and for upgrading obsolete switchgear to the new Standards. The Power Cube type PB/F fixed parts are factory-assembled and tested and, where applicable, comply with IEC 62271-200 and IEC 62271-1 Standards. The fixed parts allow construction of arc proof switchgear - classification LSC2B-PM IAC BFLR or LSC2B-PM AFLR according to IEC 62271-200 (in accordance with IEC 62271 Standards for general characteristics).

Guide Sleeve for SwitchgearSwitchgear handle The switchgear handle is a crucial component designed for the safe and efficient operation of electrical switchgear systems. Typically constructed from high-quality materials like stainless steel or durable plastic, the handle is engineered to provide a firm grip and smooth motion, ensuring ease of use during the operation of circuit breakers, isolators, and other switchgear devices. It plays a key role in manual control, enabling operators to easily open or close electrical circuits, ensuring that the switchgear operates within defined safety protocols.

VBI-12 Indoor High Voltage Vacuum Circuit Breaker is three-phase AC 50Hz, rated voltage of 12KV indoor device, for industrial and mining enterprises, power plants and substations as electrical equipment control and protection purposes, and for frequent operation of the place.which combined the technology of the ABB corporation in Switzerland and developed in China. Product complies with the standard GB1984 & IEC62271-100. VBI-12 VCB usually mounted into switchgear panel KYN28 and XGN. It is applicable in occasions with frequent operation, has functions of high-speed recloser, Multiple Opening/Closing, reliable mechanical interlock. It has fixed type & withdrawable type. It adopts the composite insulated material, there is no pollution and explosion danger, the insulation level is high.

SOLH 3V series 3/2-way pneumatic solenoid directional control valves are engineered with both direct-acting and pilot-operated structures, tailor-made for driving single-acting spring return cylinders and switching vacuum pneumatic circuits. Available in Normally Closed (NC) and Normally Open (NO) configurations, this series adopts high-strength lightweight aluminum alloy valve bodies with compact layout, rapid response and IP65 dustproof & waterproof protection grade, acting as the standard core control component for small and medium-sized pneumatic automation systems. The port layout follows universal industry standards: P for main air inlet, A for execution working port connecting cylinders or vacuum suckers, R for exhaust port matched with silencers to lower operational noise. Direct-acting 3V1 and 3V2 variants support reliable zero-pressure startup within 0~0.8 MPa with switching response under 0.05s, perfectly fit for low-pressure gas pipelines and negative-pressure vacuum control scenarios. Pilot-operated 3V100/3V200/3V300 series features larger flow capacity and lower coil power consumption, requiring a minimum inlet pressure of 0.15 MPa for stable switching to satisfy high-flow conventional pneumatic loops. Equipped with a thimble-style manual override button for convenient on-site debugging during installation and maintenance, the whole series supports oil-free operation with stable sealing performance. Multiple thread specifications including M5, G1/8, G1/4 and G3/8 are optional, paired with mainstream global AC & DC voltages and two wiring modes of DIN socket and flying leads. It can directly replace traditional 3A air pilot valves and 3L hand pull valves without structural modification, widely deployed in workpiece clamping jacking mechanisms, vacuum adsorption switching, pneumatic interlock protection and inching control of small actuators.
