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.

Switchgear Grounding Switch and its operating mechanism is a newly developed product of our company, its structure adopts assembly, with the advantages of small switch operating power. The product performance meets the requirements of GB1985-2004 High-voltage AC Disconnector and Ground Switch and IEC6227-102:2002. Applicable in MVnetHP (AP) intermediate switchgear, protect other electrical equipment in switchgear from damage, as grounding protection during maintenance of high voltage electrical equipment.

SOLH CDJ2 stainless steel pen-type mini pneumatic cylinder is fully interchangeable with SMC CJ2 series, available in bore sizes φ6/10/16 with built-in magnetic ring compatible with magnetic position switches. Constructed with 304 stainless steel barrel and piston rod for rust resistance and mild anti-corrosion performance, suitable for humid, food-grade, medical and clean environments. Tie-rod-free crimped end cap design delivers compact and lightweight outline. Complete variants cover CDJ2B double acting standard type, CDJ2E single acting spring return, CDJ2ET single acting spring extend, and CDJ2KB non-rotating hexagonal piston rod for anti-twist positioning. Standard rubber cushion; Z air cushion is optional for φ10/16 to reduce impact at high speed. Minimum starting pressure reaches 0.06MPa, supporting oil-free continuous operation with service life over 5 million cycles. A full set of mounting accessories including flange, foot bracket and double clevis is available. Compared with C85 and MI mini cylinders, CDJ2 provides richer specifications and better cost performance. Widely used for high-frequency linear push-pull motion in confined-space equipment for 3C testing, food machinery and medical automation. A minimum 50% safety margin on thrust is recommended during selection.
