The EV 251B valve with assisted lift can operate at a differential pressure from 0 to 10 bar. This 2/2-way valve is ideal for use in closed-loop systems with low differential pressure or for open systems with differential pressure dropping to zero. The valve body is made of dezincification-resistant brass. Medium temperature up to 70 °C.

The EV250B is compatible with a range of Danfoss coils with protection ratings from IP00 to IP67.

• 2-way
• Solenoid operated
• Valve body: brass
• Seal material: NBR
• ISO 228/1
• Closed when de-energized

Danfoss valves offer a balanced ratio between high quality and affordable price. They are maintenance-free and will serve you for many years.

Benefits from Exceptional Features

1 Clip-on Coil
The very convenient clip-on coil system allows for easy and secure assembly and disassembly without the use of tools. Hermetic sealing to prevent moisture ingress is also available on request.

2 Range of Coils up to IP67 Protection
The range of coils with protection from IP00 to IP67 offers optimal solutions for various applications.

3 Improved Water Hammer Damping
Controlled damping in the final stage of closing, optimized diaphragm assembly shape, and balancing nozzle reduce water hammer in all valves to as low as 1.5 bar (according to EN 60730-2-8 standard, at a test pressure of 6 bar).

4 Long Life and High Performance
The valve's lifespan is significantly extended thanks to a specially shaped diaphragm that reduces rubber stress levels. This special shape also ensures optimal flow.

5 Insensitivity to Contamination
The built-in filter protecting the valve's pilot system is self-cleaning. If the balancing nozzle becomes clogged with dirt, it is easy to clean.
