GN30-12 type rotary indoor high-voltage isolating switch is a new type of isolating switch with rotary contact knife. The main structure is that the upper and lower planes of the three-phase common chassis are fixed with two sets of insulators and contacts, and the switch is opened and closed by rotating the contact knife. 1.Extractable version Shake in/out with the door closed 2.Can be used in all types of facilities and equipment 3.Due to the limited number of components and the use of mass production systems for manufacturing, it has very reliable controllability 4.Easy and convenient maintenance 5.Multiple types of functional units that can be used for various solutions

SOLH ASC series one-way exhaust throttle valve, AirTAC standard aluminum alloy in-line pneumatic flow control valve. Thread-type without push-fit joint, lock anti-vibration adjustment nut, exhaust throttling for double-acting cylinder speed regulation. Models ASC100-06, ASC200-08, ASC300-10, ASC300-15 with PT/G/NPT thread options, ideal for general-purpose automated pneumatic circuits.

SOLH 4M series plate-type 5/2-way solenoid valves strictly comply with international NAMUR mounting standards, purpose-built for direct assembly onto pneumatic actuators driving ball valves and butterfly valves. The integrated bottom base comes with pre-embedded P, A, B, R1 and R2 air passages, enabling seamless docking with actuator air cavities without external tubing for A/B working ports. This streamlined layout drastically cuts pipeline layout workload and potential air leakage points compared with conventional tube-connected 4V series solenoid valves. This lineup adopts internal pilot spool construction with oil-free operation, offered in single-coil spring reset (4M×10) and double-coil latching memory (4M×20) configurations covering three size grades: 4M100, mainstream 4M200 and high-flow 4M300. Single electric control variants automatically reset under spring tension once power is disconnected for fail-safe reset scenarios, while double electric control versions retain their switching position steadily after power cut to sustain valve opening/closing status for long-term pipeline locking. Each unit is fitted with a side-mounted manual override button for convenient offline commissioning and maintenance testing. Coils support widely used global AC/DC voltages with IP65 dustproof and waterproof ingress protection, suitable for rigorous working conditions in water treatment, chemical pipelines and general industrial fluid switching. The series is dimensionally compatible with manifold bases shared with the equivalent 4V series, supporting standalone actuator installation or centralized valve island assembly via multi-station manifolds. With certified standard NAMUR interface, interchangeable with mainstream Airtac 4M series, it serves as a dedicated matched control component for automated on-off regulation of pneumatic ball and butterfly valve actuators.

The electrical switchgear gasket is a vital component designed to provide an effective seal between various parts of a switchgear assembly. Made from high-quality, durable materials such as silicone rubber, EPDM (Ethylene Propylene Diene Monomer), or neoprene, these gaskets are engineered to withstand extreme temperatures, environmental conditions, and electrical stress. The gaskets come in various shapes and sizes to fit different switchgear designs, ensuring a snug fit that prevents dust, moisture, and contaminants from entering the enclosure. Additionally, they exhibit excellent resistance to aging, UV rays, and chemicals, enhancing the longevity and reliability of the switchgear system.
