Control valve with own-medium control for the regulation of pressure and flow rates in service areas without external power supply. Long service life due to the hard-faced and thus wear-resistant, corrosion- and infiltration-proof seat. Suitable for use in water distribution applications and in pressure management.
Face-to-face length: acc. EN558-R1 (DN 50 - DN 250)
With flange ends on both sides acc. to EN 1092-2
Slotted cylinder as standard control insert for cavitation-free regulation
Valve controlled by its own medium
Welded valve seat enhances resistance to wear
Independent of variations of the inlet pressure / flow rate, the valve regulates a higher inlet pressure to a constant, lower outlet pressure
Pre-formed diaphragm with sealing bulges
Chambered and pull-out proof profiled sealing ring
