The ZR differential valve is designed for installation in a central heating system with forced water circulation - a circulation pump. Its task is to protect the pump system against damage due to overheating and pressure that may occur when the pump stops forcing circulation. During pump operation, the valve remains closed. When the pump is interrupted, e.g. due to a voltage failure, the valve opens automatically, allowing gravity circulation of water.

The valve can operate in an installation whose pressure does not exceed 6 bar (60 meters of water column), and the temperature reaches a maximum of 110 ° C. During operation, the valve does not require any maintenance. Made in Poland.

Specifications:

operating temperature 0-90°C, instantaneous 110°C, nominal pressure 0.001-6.0 bar, permissible pressure up to 7.00 bar, valve opening pressure with gravity circuit 0.00-0.001 bar, nominal cross-section of the valve flow 98-100% of the nominal cross-section of the installation, noise level during the work cycle up to 25 dB (A)
