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.

SOLH VM2 (VM200) medium mechanical poppet valve is fully interchangeable with matching SMC models. Featuring medium poppet construction with Cv=0.87 flow coefficient, its flow capacity is around 8 times higher than mini VM1 series, equipped with standard Rc1/4 port and optional NPT/G1/4 threads. It works under 0~1.0MPa and is incompatible with vacuum, adopting lubrication-free wear-resistant poppet seal and robust metal body. Side port and bottom port piping layouts are available, supported by a complete lineup of interchangeable actuators: standard POM roller / hardened steel abrasion-resistant roller lever, one-way anti-rebound roller, straight plunger, flat pushbutton, yellow mushroom emergency stop head, green indicator button and lockable hinge knob. The hardened steel roller variant fits heavy-duty high-wear production lines. Widely used for cylinder & slide table stroke limit detection, equipment manual jog commissioning, jig fixture air switching and safety emergency interlock, it serves as the mainstream mechanical air trigger valve for packaging, textile, printing and general automation production lines.
