The EV251B 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. Media temperature up to 70 °C.

The EV251B 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
• Normally closed

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. On request, hermetic sealing is also available to prevent moisture ingress.

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

3 Better water hammer damping
Controlled damping in the final closing stage, an optimised diaphragm assembly shape, and a compensating nozzle reduce water hammer in all valves to as low as 1.5 bar (according to EN 60730-2-8, at a test pressure of 6 bar).

4 Long lifespan 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 compensating nozzle becomes clogged with dirt, it can be easily cleaned.
