*Please note that cast bronze valve bodies, when in pipe systems according to DIN are only suitable up to PN 16 max., cast stainless steel
bodies up to PN 25. All pressures are gauge pressures. Min. control pressure for actuators 3 and 4 depends on operating pressure. Kv values
determined acc. to IEC 534 standard, body with threaded sockets DIN ISO 228.
The Kv value data refers to control function 1 (NC) and the largest actuator for each nominal size.
Kv values may be different for other combinations.
