Selection Tips

1, Voltage Matching: AC220V is for standard mains power; DC24V/12V are better for industrial control, vehicle, and low-voltage systems. Always confirm the coil voltage to avoid burnout.

2,Temperature Limits: The seal material determines the maximum operating temperature. For example, NBR (80°C max) is not suitable for continuous use in hot water above 80°C, as it will degrade and leak.

3,Media Compatibility: Oily media requires VITON seals, as NBR will swell and fail in oil. Steam applications should use VITON or higher-grade seals.

4,Size Consistency: Always match the valve size to your pipe's nominal diameter. Using a smaller valve will restrict flow and shorten its lifespan.

Our Advantages:

1, "The valve body is made of stainless steel (typically 304 material) , which offers much better corrosion resistance than brass. Whether you use it in water treatment, food equipment, or outdoor environments, the valve body itself will never rust. Moreover, it features a direct-acting diaphragm structure with no minimum pressure requirement - it works perfectly even under very low water pressure, completely solving the embarrassing problem of 'valve installed but won't open'."

2, "The standard configuration comes with FPM (FKM) fluorocarbon rubber seals, which can withstand temperatures up to about 120°C (depending on actual operating conditions). It offers significantly better oil resistance, acid/alkali resistance, and aging resistance. Even if you're using room-temperature media, choosing FPM seals gives you longer durability and reduces the hassle of frequent replacements down the line."

3, "We offer three port sizes: 4分 (DN15), 6分 (DN20), and 1 inch (DN25). Just pick the size that matches your equipment's port - no adapters needed, making installation very convenient. For voltage, we have both AC220V and DC24V in stock - whether you're connecting to a household outlet, a PLC, or battery power, we've got you covered. The coil has an IP65 protection rating, so it's resistant to splashing water and dust - suitable for use in workshops, pump houses, outdoor cabinets, and similar environments."

4, "The coil on the 2WS2 is replaceable (secured with a nut). If the coil ever gets water damaged or burns out, you only need to spend a small amount on a replacement coil and install it yourself - no need to disassemble the piping or buy an entirely new valve. This saves you considerable maintenance time and cost."
