HERZ Automatic filling valve is made from brass due to its good strength and excellent corrosion resistance. Under Article 33 of the REACH Regulation (EC No. 1907/2006), we are obliged to point out that the material lead is listed

HERZ pressure-independent control valve in flanged design Body of grey cast iron GJL 250 according to EN 1561 Flange according to EN 1092, PN 16. Length according to EN 558-1, basic series 1, suitable for regulation of the flow rate, in heating and cold water systems, with test points max. differential pressure 4 bar.

Two test points for measuring the differential pressure across the valve. Actuator mounting threaded connection M 28 x 1.5, control stroke 4.0 mm. The actuating drive is not included.

When using the 1 7990 31 and 1 7708 52/53 actuators with a 5 mm stroke, the maximum flow rate is reduced. The 4006 / 4206 SMART valves with a 4 mm stroke can be driven with all linear HERZ drives. The Pressure Independent Balancing Control Valve (PIBCV) is used in all heating and cooling systems with circulation pumps.

HERZ two-port ball valve with internal thread for precise control, without leakage. Control ball valve for continuous control of cold water, hot water or air in closed circuits. Nominal pressure 40 bar

The unit allows pressure-independent control ensuring full stroke regardless of pressure fluctuations while guaranteeing a constant flow rate to the terminal unit maximizing energy efficiency. HERZ is an Austrian company, which is recognized internationally.

Herz ball valve with characteristic DZR is made of CW602N; this material has the properties of dezincification-resistant brass. The spindle of the valve can easily be connected to the actuator. The synchronization characteristic of the ball made of forged brass is integrated on the valve.

Functional principle of a PICV combination valve. A Pressure Independent Balancing and Control Valve (PIBCV or PICV) combines a regulating and control valve with a differential pressure controller. The valve has a linear characteristic. The adjustment of the required flow volume is done at the valve spindle, where the maximum stroke is adjusted.
