The flow regulator type QR is used for maintaining a constant flow of water in central heating systems. This valve is a mechanical flow restrictor, and is usually used to balance the central heating network.

We produce them with a flange connection from DN15 to DN65 and a threaded connection from R1/2” to R6”, and for nominal pressures PN16 and PN25.

All internal parts are made of stainless materials, while the housing is made of gray cast iron. The maximum operating temperature is 1500°C and they can be made for nominal pressures PN16 and PN25.

An electromotive actuator can be upgraded to this type of valve. If combined with the actuator, the valve can be used to regulate the temperature according to the slide chart.
