2S250-25 1" Stainless Steel Diaphragm Solenoid Valve AC220V DC24V
The SUW-25/2S250-25 is a 1” Inch, 2 way, Stainless Steel solenoid valve with a solenoid coil. It is compatible with a variety of media such as liquids, gas, air, fuel, glycol and weak acids. It has a temperature range between 15°F and 250°F.
The SUW-25/2S250-25 is a solid Stainless Steel valve that features 1” inch female NPT inlet and outlet ports. Its compact size is great for fitting in tight places without compromising quality.
The coil is included with the valve. The connection can be made with the 5.5” lead wires using solder or terminal connectors. The coil has a voltage tolerance of +-10%. It is rated for 100% duty cycle but should not be powered indefinitely.
There are no minimum pressure requirements and the valve can handle pressure up to 115 PSI. The valve has a 25mm orifice and its flow rate can be calculated using the Cv value of 12.

Production process of NBR Diaphragm Semi-Direct Electromagnetic Valve:
Common Probelm: My solenoid valve is not working. What could be wrong?
Point 1: The seal material is compatible with the medium that’s being put through the valve
Solution 1: Make sure there is a proper electrical connection (voltage, current, frequency) Use a multimeter to test all components.
Point 2: The valve seal and orifice are free from debris.
Solution 2: The installed position of the valve is correct. Some valves will only work in certain positions.
Point 3: The valve operates within the specific pressure range. Some valves have minimum pressures requirements to function properly.
Solution 3: The coil is disconnected or burned out. Check your wiring to the coil and confirm the valve is receiving the correct specifications. OHMs can be checked to determine if the coil has burned out.
