Coolant Block Valves

The block valve is based on Pierburg's poppet valve technology and can be easily integrated into a coolant module as a "snap-in valve". All specific interfaces are implemented and integrated as required. This eliminates the need for separate hydraulic couplings or hoses.

Highlights

• Easy assembly and system integration
• Flow rate range freely selectable – precise selection according to application requirements
• 2-way: Fail safe open or closed freely selectable thanks to modular principle for "high flow"
