LINKV electric solenoid valves are electrically operated on/off devices for flow regulation in commercial fluid systems. Available in normally closed (NC) or normally open (NO) configurations, they adopt direct-acting or pilot-operated structures to fit varied operating conditions. Stainless steel body designs make the valves compatible with water, air, gas, oil, and mildly corrosive media across multiple industrial scenarios.
Direct-acting models deliver a response time of ≤20 ms, supporting operation up to 1200 cycles per minute. Precision-machined plunger and spring components maintain consistent shutoff performance. All valves undergo life cycle testing, with results exceeding 5 million operations under rated conditions with clean media and stable voltage. Each unit receives pressure and leakage testing at 1.1× rated pressure, plus coil continuity testing before delivery.
Valve bodies come in 304 or 316L stainless steel, with optional seal materials including FKM, EPDM and PTFE. Direct-acting models operate from 0 bar to maximum rated pressure, with no minimum pressure drop requirement. The full product range supports operating pressures from vacuum to 40 bar, varying by specific model. Operating temperatures span from -20°C to +180°C based on selected seal material.
Coil power ratings range from 3W to 15W for DC supply, and 6VA to 22VA for AC supply. Coils feature Class H insulation (180°C) and IP65 or IP67 protection ratings, with 100% dielectric strength testing in production. Explosion-proof enclosures with ATEX, IECEx or CSA certification are available as an optional configuration for hazardous area installation.

These valves serve water treatment systems for raw water, softened water and chemical dosing regulation. In food and beverage processing, they work with clean-in-place lines, filling equipment and pasteurization systems with hygienic seal options. For industrial automation and pneumatic setups, they manage air, water and light oil flows for cylinder and spray system control. Marine and offshore operations use the valves for bilge water treatment, fuel transfer and cooling water systems, benefiting from saltwater corrosion resistance.
Direct-acting valves operate from 0 bar to full rated pressure, suitable for vacuum or low-pressure systems. Pilot-operated valves require a minimum pressure drop of approximately 0.5 bar to open, and support higher flow rates with lower coil power consumption.
Yes, when fitted with PTFE seals and a Class H high-temperature coil. For continuous steam service up to 180°C, the HT series with cooling fins and a specialized plunger guide is available. Confirm compatibility with specific temperature and pressure conditions with technical staff.
Standard thread options include NPT, BSPP (G), BSPT and metric threads. Flanged connections for DN15–DN50 are available upon request for larger sizes or high-pressure applications, subject to minimum order quantities.
Under rated conditions with clean media, proper voltage and no water hammer, valves demonstrate a service life exceeding 5 million cycles. For continuous cycling applications with PTFE seals and AC coils, expected service life is 2-3 years. The product includes an 18-month quality guarantee.
Yes. All LINKV solenoid valves use interchangeable coil systems. Users can loosen the retaining nut, remove the existing coil and install a replacement without shutting down the process or disconnecting pipe connections.
