The EV 251B valve with auxiliary stroke can operate at a differential pressure of 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 a degree of protection from IP00 to IP67.

• 2-way
• Coil controlled
• Valve body: brass
• Seal material: NBR
• ISO 228/1
• Closed without voltage

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

Benefits of exceptional features

1 Clip-on spool
The very convenient tilting spool system allows easy and safe assembly and disassembly without the use of tools. A hermetic seal to prevent moisture penetration is also available on request.

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

3 Better water shock absorption
Controlled damping in the final closing stage, optimized diaphragm assembly shape and compensating nozzle reduce water shock in all valves up 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 service life of the valve is significantly extended thanks to a specially shaped diaphragm, which reduces the stress level of the rubber. This special shape also ensures optimal flow.

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