SOLH AR series pilot operated pressure regulators include complete models of AR425/625/635/825/835/925/935. Adopting internal pilot relief structure, they feature high flow rate and ultra-high pressure regulation precision with hysteresis ≤0.02MPa and repeatability ≤0.01MPa. Equipped with dual pressure ranges and built-in automatic overpressure relief function, they support lubrication-free operation and arbitrary installation. Suitable for large-bore main air pipelines, high-flow equipment and precision pneumatic control systems, they are ideal stabilization solutions for factory centralized air supply systems.

Low-Voltage Switchgear Micro Switch: Product Details and Applications The low-voltage switchgear micro switch is a precision-engineered component designed to ensure accurate and reliable electrical operations in switchgear systems. It is typically a compact, sensitive switch capable of triggering with minimal physical force, making it an essential part of the control and monitoring mechanisms in low-voltage switchgear assemblies.

FKN12-12D/630-20 indoor AC high-voltage load switch is a three-phase high-voltage switchgear with a rated voltage of 12KV and a rated frequency of 50HZ. It is used for switching load current, closed-loop current, no-load transformer and cable charging current, off combined short-circuit current. The load switch equipped with the grounding switch can withstand short-circuit current.and m-ainly used in power distribution substation and industrial electrical equipment where three phase closed loop circuit or bottom power supply system for control and protection.

Switchgear Door Stopper – Product Details and Applications Product Details: The switchgear door stopper is a critical accessory designed to secure, control, and maintain the proper opening or closing of switchgear cabinet doors. Made from durable materials such as stainless steel, aluminum, or high-grade plastic, these stoppers ensure long-term resistance to corrosion, mechanical stress, and environmental wear. Many models come with adjustable arms or rubber-padded ends to absorb impact and prevent damage during sudden door movements. Switchgear door stoppers can be spring-loaded or magnetically operated, ensuring smooth and stable operation. Additionally, some variants integrate anti-vibration features to prevent door movement due to mechanical operations, such as relay switching or breaker tripping. Their compact design allows for easy installation, either by screwing or clipping onto the door frame or cabinet base.

SOLH MK (commonly named MKB) is a combined pneumatic cylinder integrating 90° rotation and linear downward clamping, interchangeable with mainstream MKB series. Bore sizes cover φ12~φ63 and clamping strokes range from 5 mm to 50 mm. Its overall length is shortened by 3~10 mm compared with conventional MK2 models for more compact layout. The allowable inertia torque is upgraded threefold to cope with high-speed clamping of high-inertia workpieces, and the maximum clamping force of φ63 bore reaches 12.4 kN under 0.5 MPa for reliable heavy-load holding. Working cycle: retract upward → 90° left/right rotation → extend for clamping; release follows reverse sequence. Fixed 90° rotation angle with tolerance ±5° ensures stable repetitive positioning. Except φ20 and φ25 bores with 2-side sensor mounting only, other sizes support 4-direction magnetic switch installation for neat wiring without interference. Through holes and double-end threaded holes enable direct mounting and flange installation. Double-side rubber buffers reduce impact, vibration and noise; oil-free design satisfies clean & dust-free working environments. Built-in magnetic rings work with position sensors to monitor clamp/release status; clockwise RZ and counterclockwise LZ rotation directions are optional. It is widely applied in machine tool fixtures, welding positioning, stamping fixing, precision 3C components, semiconductor tray clamping and fixture flipping limiting. It simplifies mechanical design and saves installation space by integrating rotating and clamping functions. Select bore size with clamping force ≥ actual load × 1.5 safety factor and reserve 3~5 mm stroke margin to avoid mechanical collision.

The Switchgear Mechanism Interlocking Plate is a critical component in electrical switchgear systems, designed to enhance safety and operational reliability. Made from high-strength materials such as stainless steel or reinforced composites, this interlocking plate is engineered to withstand harsh environmental conditions and high mechanical stress. It ensures proper alignment and secure locking of various switchgear components, preventing unauthorized or accidental operation of the equipment.
