Key features

• DN 40; Kvs 25 m³/h; stroke 15 mm.
• Medium: water, water with a maximum of 50% vol. glycol.
• Medium temperature: -10...120°C [14...248°F].
• Flow characteristic: equal percentage, optimised in the opening range.
• Permissible leakage: max. 0.05% of Kvs value.
• Body: EN-GJL-250 (GG 25); closing element and stem: stainless steel; stem seal: EPDM O-ring.
• Permissible mounting position: from vertical to horizontal in relation to the stem; installation with the stem pointing downwards is not permitted.

For a medium temperature of -10...2°C, the technical data sheet specifies that stem heating is required. Observe the flow direction indicated by the arrow on the body. Maximum differential pressure and closing pressure depend on the actuator fitted.
