Technical data

Working medium
Corrosive, inert, gaseous and liquid media which have no
negative impact on the physical and chemical properties of
the body and seal material.
Max. perm. pressure of working medium
Media temperature
Max. permissible viscosity
Other versions for lower/higher temperatures and higher viscosities
on request.

All pressures are gauge pressures. When the flow is over the seat (M), there may be the danger of water hammer with liquid media!
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. 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.
