China 4M series NAMUR solenoid valve Manufacturer, Supplier, Factory

SOLH IR412-04-X32 pilot operated precision regulator is fully interchangeable with SMC equivalent models. Adopting nozzle-flapper relief structure with Rc 1/2" main port, this X32 customized rear exhaust version features adjustable pressure range of 0.01~0.7MPa and ultra-high sensitivity of 0.2% full scale, with steady air consumption less than 1 L/min. It boasts remarkable flow and relief performance, while rear exhaust design avoids dust and oil mist pollution. Available with panel or bracket mounting and optional front/rear pressure gauge, it provides ultra-stable pressure output for precision dispensing, lithium battery film tension control, large-bore cylinder positioning and semiconductor cleanroom pneumatic systems.

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.

Vacuum circuit breaker is the most commonly used type of high-voltage circuit breaker, mainly divided into two kinds of indoor and outdoor. We mainly focus on indoor vacuum circuit breakers. (Indoor circuit breakers: High-voltage circuit breakers that do not have the performance of protection against wind, rain, snow, ice and dense frost, etc. and are suitable for installation and use inside buildings.) The vacuum circuit breaker is named after its interrupting medium and the insulating medium of the contact gap after interrupting is high vacuum; it has the advantages of small size, light weight, suitable for frequent operation and interrupting without maintenance, and is more popularly used in the 3kV-40.5kV distribution network. The components of vacuum circuit breaker are vacuum interrupter, electromagnetic or spring-operated mechanism, bracket and other parts. Vacuum interrupter is the core component of vacuum circuit breaker, its main role is, through the excellent insulation of the vacuum inside the tube to make the medium and high voltage circuit cut off the power can quickly extinguish the arc and suppress the current to avoid accidents and accidents.

The VSG-12 indoor high-voltage vacuum circuit breaker is designed for use in indoor switchgear applications within 12kV power systems with a three-phase AC 50Hz rated voltage. It serves as a crucial protective and control unit for power distribution equipment and industrial facilities. This circuit breaker is suitable for environments that require frequent operations at the rated current or the capability to interrupt short-circuit currents multiple times. The circuit breaker features a modular design, where the operating mechanism and the circuit breaker body are separable, allowing for quick replacements and assembly. VSG vacuum circuit breaker is a new indoor switchgear. It is mainly used for three-phase AC power system with rated voltage of 12kV and rated frequency of 50-60HZ. It has the advantages of compact structure, high reliability, small operation vibration and easy maintenance. It can be widely used in power plants, steel mills, metallurgy, petrochemical, transportation, buildings and other industrial and mining enterprises. As a switchgear for protecting high-voltage motors, transformers, line faults and other loads.
