China VEX1 high flow regulator Manufacturer, Supplier, Factory

FN18 load switches and load switch-fuse combinations are high-voltage, high-performance load switches combining compressed-air arc extinguishing and gas-produced arc extinguishing. The combination of load switch and fuse combines the advantages of the load switch with those of the fuse to switch any load current up to the rated breaking current of the load switch, and to switch any overcurrent up to the rated short-circuit breaking current of the combination by means of the operation of the fuse and its impinger. It is used in three-phase power distributions of AC 50Hz rated voltage 12kv and rated current 630A Esp For power ring network in city net work construction improvement high-rise buildings and public facilities as an ideal product to protect package substation and transformer It has the features of advanced design simple operation impact structure smart appearance light weight complete function fast on-and off speed and high reliability.

SOLH VNB201 external air pilot operated 2-way fluid valve is driven by 0.25–0.7MPa pilot air to realize zero differential pressure startup, performing stable switching under vacuum, low pressure and zero pressure difference. Adopting balanced poppet structure, it features low flow resistance, high flow capacity and bidirectional fluid passage for flexible pipeline layout. Valve bodies are available in brass, stainless steel and aluminum alloy, matched with NBR/FKM/EPR seals to suit compressed air, water, oil, vacuum, inert gas and mild acid/alkaline fluids. Without built-in electric parts, it generates no electric sparks and fits explosion-prone environments. Mountable at any angle with port sizes ranging from 3/8" to 1", it is widely applied in cooling water, lubricant oil, vacuum handling, chemical, food, pharmaceutical and flammable fluid pipeline on-off control.

SOLH VM4 (VM400) medium 3-port poppet mechanical valve is fully interchangeable with equivalent SMC models, positioned between mini VM1 and high-flow VM2 series. Its core advantage lies in compatibility with full pressure range from -100kPa vacuum to 1.0MPa positive pressure, a feature unavailable on VM2. It adopts standard Rc1/8 port with optional NPT/G1/8 threads and Cv=0.38 flow capacity, supporting side and bottom port piping layout. Built with solid metal body, it withstands 1000m/s² impact and heavy vibration, suitable for harsh heavy-duty production lines, with lubrication-free dust-resistant poppet sealing for long service life. A complete set of interchangeable actuators are provided: standard / hardened anti-abrasion steel roller lever, one-way anti-rebound roller, straight plunger, multi-color mushroom emergency stop buttons, 2/3-position rotary knobs, lockable pushbuttons and toggle hinge levers. Widely applied in cylinder & slide table stroke limit detection, vacuum adsorption/release circuits, equipment manual jog commissioning, machine safety emergency interlock and jig fixture switching, it is the ideal medium mechanical trigger valve for working conditions requiring vacuum compatibility and strong shock resistance.

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.
