This electrically operated on/off valve delivers precise flow control for water, air, gas, oil, and mildly corrosive media in hazardous industrial settings. Manufactured from 304 or 316L stainless steel, it is available in direct-acting or pilot-operated designs, with normally closed (NC) or normally open (NO) configurations. Threaded ends are standard, with flanged connections available on request. Built for commercial procurement and industrial fluid automation systems, production follows ISO 9001 quality management protocols. Every unit undergoes pressure and leakage testing at 1.1× rated pressure before delivery to verify performance consistency.
For hazardous area installation, the valve offers explosion-proof enclosures rated Ex d IIC T4/T6 and intrinsically safe coils with ATEX, IECEx, or CSA certification. These configurations suit Zone 1, Zone 2, or Class I Division 1 environments. Coils meet Class H insulation standards for elevated temperature operation. Standard models carry IP55 protection, with IP65 or IP67 options available for dusty or humid conditions.
The 304 or 316L stainless steel body and plunger tube provide resistance to rust and saline environments. Users can select FKM, EPDM, or PTFE seals to match specific media and temperature requirements. NBR seals support -5°C to 85°C, silicone seals support -5°C to 120°C, and FKM seals support -40°C to 150°C. For steam service up to 180°C, PTFE seals with cooling fin structures are available.
Direct-acting models operate from 0 bar to maximum rated pressure, with no minimum pressure drop required. This design fits vacuum systems, gravity-fed pipelines, and low-flow applications where pilot-operated valves cannot function. Pilot-operated configurations support higher flow rates and require a minimum pressure differential to operate. Coil power consumption ranges from 3W to 15W (DC) and 6VA to 22VA (AC), with all coils tested for dielectric strength during production.

These valves serve multiple industrial use cases. They control raw water, chemical dosing, and backwash flows in water treatment systems, with stainless steel construction supporting mildly aggressive chemicals. In gas distribution networks, ATEX-certified models perform emergency shut-off functions in hazardous zones. Additional applications include industrial pneumatic systems, marine offshore cooling circuits, and commercial heating steam lines, matching diverse operational requirements.
Direct-acting valves operate from 0 bar to full rated pressure, suitable for vacuum or low-pressure setups. Pilot-operated valves require a minimum 0.5 bar pressure drop to open, supporting higher flow rates with lower coil power.
Yes, with PTFE seals and Class H high-temperature coils. For continuous steam service up to 180°C, models with integrated cooling fins and specialized plunger guides are recommended. Confirm conditions with our engineering team for precise selection.
Standard threads include NPT, BSPP (G), BSPT, and metric types. Flanged connections for DN15–DN50 are available on request for high-flow or high-pressure installations, with minimum order quantities applying.
Yes, all models use interchangeable coil systems. Users can loosen the retaining nut and replace the coil directly, no need to shut down the process or disconnect pipeline connections.
