SOLH VT307 is a compact direct-acting 3-port poppet solenoid valve with elastic rubber seal. It realizes zero-pressure startup and stable operation under 0–0.7MPa positive pressure or full vacuum down to -101.2kPa. Optional NC, NO, flow division and selection functions are available, with response time ≤20ms and max switching frequency up to 10Hz. Lubrication-free soft seal and built-in manual override simplify on-site debugging, and its mini body supports manifold stacking installation. Widely used in automated assembly, robots, vacuum suction jigs, blowing stations, packaging, printing and food machinery, it adopts imported core parts and serves long-term clients including Foxconn, Huawei, Midea and Gree.

interlocking mechanism for switchgear Switchgear Interlocking Mechanism - Product Details and Applications The Switchgear Interlocking Mechanism is a critical safety and operational component designed to ensure the secure and coordinated operation of electrical switchgear. This mechanism prevents inadvertent or unauthorized operation of switches, breakers, and other electrical equipment by establishing a series of interlocking conditions. Typically installed within the switchgear panel, the interlocking mechanism is activated during specific operational sequences to prevent the opening or closing of certain parts unless predefined conditions are met.

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.

Our commitment to precision and excellence ensures that each screw meets stringent industry standards and performs reliably in demanding environments.

SOLH AN series pneumatic exhaust silencer is fully interchangeable with equivalent SMC mufflers, covering a complete size range from M5 micro thread to Rc2" large bore, available in flame-retardant sintered resin and high-temperature sintered copper metal versions. It achieves 25~35dB(A) noise reduction. The double-layer composite structure effectively suppresses high-speed exhaust impact noise from solenoid valves and cylinders, blocks oil mist splashing, and maintains low exhaust back pressure without slowing down actuators. The resin variant operates from -10 to 60℃ with UL94-V0 flame retardant housing, while sintered metal type withstands up to 150℃ for frequent high-temperature exhaust environments. The full lineup suits solenoid valves, cylinders and centralized exhaust headers, classified into micro, medium and industrial large-bore models by airflow capacity, with metric, Rc, NPT and push-in connection options. Clogged silencer cores can be cleaned by reverse air blowing, serving as essential noise reduction environmental accessories for all pneumatic circuits.
