Electrical Switchgear Spacers are essential components designed to maintain precise alignment and spacing within electrical switchgear assemblies. These spacers play a critical role in ensuring the proper functioning and safety of electrical systems by providing necessary insulation and mechanical support between various switchgear parts.

SOLH VEX1 balanced poppet 3-way relief pressure regulator adopts poppet structure instead of traditional diaphragm design, delivering 3~5 times higher flow than standard AR regulators with oversized relief port for fast pressure relief and stable back pressure. It achieves superior regulation precision with hysteresis ≤0.03MPa, repeatability & sensitivity ≤0.01MPa. Two control modes are available: remote air pilot and integrated solenoid pilot for automatic multi-stage pressure switching. Max inlet pressure reaches 1.0MPa, with port sizes ranging from 1/8" to 2". Mountable at any angle and lubrication-free for dry oil-free air circuits; air pilot version works 0~60℃ while solenoid pilot variant ranges 0~50℃. Widely used for large air tank pressure stabilization & rapid relief, high-flow air blowing, large bore cylinder / air motor driving and multi-stage tension control systems for film & wire manufacturing.

SOLH IS3000 piston-type mechanical pneumatic pressure switch is fully interchangeable with equivalent SMC models. Air pressure pushes the built-in piston to actuate a 1NO+1NC micro contact switch, with adjustable pressure range 0.1~0.7MPa, hysteresis ≤0.05MPa and repeatability ±0.05MPa. Die-cast aluminum housing reaches IP40 dustproof grade, equipped with top adjustment knob and graduated window for offline pressure setting without power supply. Standard port Rc1/4, optional NPT1/4 thread, IS3100 gasket mounting version and IS3010 micro-load variant dedicated for PLC, as well as indicator light optional model. Its solid piston mechanical structure delivers outstanding shock and vibration resistance, stable on vibratory feeders, knocking hammers and stamping machines without signal drift or false triggering common to digital electronic switches. Max contact load 1A allows direct driving of miniature solenoid valves or connection to PLC digital inputs, widely applied for main air source low-pressure protection, cylinder clamping position confirmation and pneumatic safety interlock for vibration equipment. It provides higher electrical load capacity than IS10 reed switches and better cost performance & vibration stability than ISE30A digital pressure switches.

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.
