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

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

• 2-way
• Controlled by a coil
• Valve body: brass
• Seal material: NBR
• ISO 228/1
• Closed without voltage

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

Benefits from exceptional features

1 Clip-on coil
The very convenient snap-on coil system enables simple and safe assembly and disassembly without the use of tools. A hermetic seal to prevent moisture penetration is also available on request.

2 A range of coils up to IP67 protection
The range of coils with protection from IP00 to IP67 offers the optimal solution for different applications.

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

4 Long service life and high performance
The life of the valve is significantly extended thanks to a specially shaped membrane that reduces the stress level of the rubber. This special shape also ensures optimal flow.

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