1. Material Parameters

• Valve Body: Brass (for conventional water/air media), Stainless Steel (304/316, for corrosion-resistant media), Cast Steel (WCB, for medium and high pressure applications)

• Valve Core: Stainless Steel, Fluoroplastics (PTFE, resistant to strong acids and alkalis)

• Seals: Nitrile Rubber (NBR, oil and water resistant), Fluoroplastics (FKM, resistant to high temperature corrosion), Silicone (for food-grade media)

• Coil Housing: Engineering Plastics, Metal Shielding (anti-electromagnetic interference)

2. Specification Parameters

• Nominal Diameter: DN1~DN200 (corresponding to 1/16"~8")

• Nominal Pressure: 0~16MPa (covering low-pressure, normal-pressure to medium- and high-pressure applications)

• Connection Method: Threaded connection (small diameter), Flange connection (large diameter), Welded connection (high-pressure applications)

3. Control and Operating Parameters

•Power Supply Voltage: AC220V, AC110V, DC24V, DC12V (standard specifications)

•Control Method: Normally closed (power-off valve closes), Normally open (power-off valve opens), Self-holding (low power consumption)

•Operating Temperature: -40℃~200℃ (depending on seal material)

•Media Type: Water, oil, gas, weak acid/weak alkali solution, steam (dedicated steam type)

•Protection Rating: IP65 (standard dustproof and waterproof), IP67 (waterproof immersion)

•Response Time: ≤0.5 seconds (small diameter), ≤3 seconds (large diameter)

• Fast response speed and efficient start/stop: The valve core opening and closing action is completed instantly when the coil is energized/de-energized, with a response time as low as 0.5 seconds. This is suitable for automated production lines and fluid control loops that require rapid switching of fluid pathways.

• Simple structure and easy installation: No complex transmission components, small size and light weight; threaded/flange connections allow direct connection to pipelines without additional supports or control accessories, saving installation space and costs.

• Convenient control and strong compatibility: Can be directly controlled via on/off signals, eliminating the need for positioners, solenoid valves, or other accessories. Seamlessly integrates with PLCs, relays, sensors, and other automation equipment, adapting to various control systems.

• Wide range of media compatibility and high cost-effectiveness: Available in brass, stainless steel, and cast steel valve body materials, combined with different seals, suitable for various media such as water, oil, gas, steam, and weak acids/alkalis; procurement and operating costs are significantly lower than pneumatic and electric valves, making them suitable for large-scale batch applications.

• Safe and reliable with low maintenance costs: The normally closed design automatically shuts off the valve in the event of a power outage, effectively preventing media leakage; only the seals are vulnerable parts, making replacement quick and easy, requiring minimal daily maintenance and resulting in a low failure rate.

• Civil Building Sector: Water/gas circuit control for household water heaters, wall-hung boilers, and central air conditioning systems; automatic start/stop of building tap water and fire sprinkler systems.

• Industrial automation: On/off switching of fluid transport pipelines in production lines; oil circuit control of air compressors and hydraulic systems; acid and alkali solution pipeline control in electroplating and coating workshops.

• Water treatment: Control of chemical dosing pipelines in wastewater treatment plant dosing systems; automatic water circuit switching for pure water machines and water purifiers.

• Food and beverage sector: Raw material conveying pipeline control for beverage bottling production lines; On/off control of steam and cooling water circuits in food processing equipment (food-grade silicone seal).

• In the field of HVAC: zoned control of chilled and hot water pipes in central air conditioning systems; interlocking control of air valves in fresh air systems; and branch circuit on/off regulation in heating.
