China ABB MDmax-ST cabinet door hinge safety interlock design Manufacturer, Supplier, Factory

Newly developed load break switch, applied on SF6 RMU. With features of high efficiency, safety, reliability, simple structure, flexible operation, interlock reliable, easy to install and so on. It satisfies with standard IEC94, GB3804, GB16926 and so on. The FL(R)N36 Indoor AC High Voltage SF6 Load Break Switch and LBS-Fuse Combination are designed for use in three-phase AC 50/60Hz RMUs (Ring Main Units) and terminal power stations. These switches are suitable for protecting power systems operating at 10kV, 24kV, and 35kV under on-load conditions. They are capable of interrupting on-load current, closed-loop current, no-load transformer capacity, and cable charging current. When equipped with a fuse combination, they can cut off any current within the range of the rated short-circuit breaking current. These devices find application in RMUs and combined transformers, among others.

SOLH IRV10 and IRV20 series precision vacuum regulators are specially designed for negative-pressure pneumatic circuits, with an adjustable vacuum range of -100kPa~-1.3kPa and ultra-fine adjustment resolution. Equipped with a self-locking knob, it effectively prevents pressure drift caused by vibration. Featuring large flow rate, low air consumption and lightweight structure, it supports dual-side and rear single port styles with diverse mounting methods. It is a standard precision control component, widely used in automated vacuum picking, electronic assembly, auto processing, air leak testing and packaging machinery.

SOLH 3L series 3/2-way hand pull directional control valves follow standard industry specifications with a default Normally Closed (NC) structure equipped with automatic spring return. Operated via straightforward axial push-pull handle movement, this manual pneumatic valve requires no electric parts or pneumatic drive signals, making it an intrinsically safe manual switching component for pneumatic circuits. It is widely deployed for single-acting cylinder actuation, circuit on-off switching, inching commissioning and safety interlock systems, especially ideal for field debugging, emergency cut-off and explosion-prone working environments. The three-port layout complies with universal industry standards: P for main compressed air inlet, A for working output port connecting single-acting cylinders, and R for exhaust port compatible with standard silencers to reduce exhaust noise. Under normal released status, the built-in return spring presses the precision spool to seal the P inlet; port A links to R for pressure relief to maintain the closed safe state. Manual pulling of the handle shifts the spool to connect P and A ports for air supply to drive cylinder movement. Once released, the spring instantly resets the valve, cutting air intake and exhausting residual pressure to prevent unintended continuous operation. Constructed with robust aluminum alloy housings and low-friction precision spools, the valve supports lubrication-free operation with stable sealing performance. Four size grades ranging from compact 3L100 up to heavy-duty 3L400 cover thread specifications M5, G1/8, G1/4, G3/8 and G1/2; PT, NPT and G thread options are available to satisfy global installation demands. The valve supports panel mounting and base mounting, sharing identical installation dimensions with the 3A air-operated valves for seamless interchange between manual and pneumatic control modes. Without any electrical components, it delivers spark-free operation suitable for flammable, dusty and humid workshops, commonly used for manual clamping, ejection cylinder control, equipment maintenance safety lockout and combined manual-pneumatic logic control systems paired with 3A pilot valves.
