7 Technical data

7.1 Medium

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.

Control medium: Inert gases

Max. permissible viscos-

ity:

600 mm²/s (cSt)

Other versions for lower/higher temperatures and higher viscosities on request.

7.2 Temperature

Media temperature: -10 — 180 °C

for special function G: -10 – 60 °C

with special function S: -10 – 60 °C

Ambient temperature: -10 — 60 °C

Control medium temper-

ature:

0 — 60 °C

Storage temperature: -30 — 60 °C

7.3 Pressure

Operating pressure: Control function 1 (NC) - Flow direction under the seat

All pressures are gauge pressures. When the flow is over the seat (M), there may be the danger of water ham-

mer with liquid media! For max. operating pressures the pressure/temperature correlation must be observed.
