SOLH 2P series mini 2/2-way direct acting normally closed solenoid valves adopt high-strength PA66 nylon engineering plastic valve bodies, specially designed for low-cost small-flow automatic switching of compressed air, clean water and low-viscosity lubricating oil. Featuring genuine zero-pressure startup performance, the valve can open normally under 0MPa pressure difference, effectively breaking the pressure dependence of pilot-operated solenoid valves. This series adopts a mature direct electromagnetic driving structure. Under power-off status, the built-in reset spring tightly compresses the valve core to maintain a fully closed state; when energized, electromagnetic attraction lifts the valve core rapidly to conduct the pipeline, with the whole switching action finished within 0.05s for ultra-fast response. Standard configuration uses wear-resistant VITON fluororubber seals with outstanding resistance to oil, water and mild corrosive media; NBR nitrile rubber sealing is available as an optional replacement according to working conditions. The coil reaches IP65 dustproof and waterproof protection grade with Class B insulation, capable of stable continuous operation in humid workshop environments. With fixed φ2.5mm flow orifice and CV value of 0.23, two mainstream thread specifications G1/8 and G1/4 are available, paired with diverse wiring options including standard DIN socket, flying leads and indicator light sockets, together with universal AC/DC voltage options to meet global matching demands. Lightweight compact outline suits installation inside compact equipment modules. It is widely used in vacuum generator air source control, small cylinder air supply switching, equipment micro cooling water loops, automatic spraying, air compressor automatic drainage and small humidification systems, serving as a cost-effective miniature fluid control alternative to brass 2V series valves.

Version 1｜Official Product Page Long Copy (SEO-focused, ~290 words for independent website detail page) SOLH 2V series 2/2-way brass fluid solenoid valves are versatile electromagnetic on-off valves engineered for universal control of compressed air, industrial water and lubricating oil, available in two mature structural configurations: direct-acting 2V025 and diaphragm pilot-operated 2V130 & 2V250 variants. Constructed with robust forged brass valve bodies paired with high-performance sealing elements, this lineup delivers reliable switching performance covering zero-pressure startup and high-flow pipeline regulation. The compact 2V025 direct-acting model adopts a direct electromagnetic drive structure that enables normal opening at 0MPa zero pressure differential. Equipped with wear-resistant VITON fluorine rubber seals, it withstands weak corrosive media and adapts perfectly to low-pressure pipelines, vacuum loops and micro-flow spraying & cooling equipment. The pilot-operated 2V130 and 2V250 rely on medium pressure difference to drive the diaphragm, featuring remarkable large flow capacity and low coil power consumption; they require a minimum startup pressure of 0.05MPa and utilize NBR nitrile rubber seals ideal for conventional water and compressed air pipelines. All versions adopt Class B insulated coils with IP65 ingress protection and a rapid switching response within 0.05 seconds. Multiple wiring options (DIN socket, flying leads, indicator light sockets) and abundant thread specifications ranging from G1/8 up to G1 inch support flexible field installation. Widely deployed in vacuum control, equipment cooling water circuits, boiler automatic water feeding, air compressor water intake and main gas-liquid pipeline cut-off, the SOLH 2V series offers economical, stable general fluid switching solutions for full-spectrum industrial automation fluid circuits.
