Belimo H725S - 3-way globe valve

Belimo H725S – 3-way globe valve

Flanged valve for closed water systems. It can operate as a mixing valve (A+B to AB) or a diverting valve (AB to A+B). Permissible pressure values in diverting mode are lower than in mixing mode.

Key features and specifications

• DN 25, PN 16, Kvs 10 m³/h; stroke 20 mm.
• Medium: water, water with a maximum of 50% vol. glycol.
• Medium temperature: 5...150°C [41...302°F]; 120°C up to 1600 kPa, 150°C up to 1400 kPa.
• Flow characteristic: A – AB equal percentage, B – AB linear.
• Permissible leakage: A – AB max. 0.05% of Kvs value; B – AB max. 1% of Kvs value.
• Pipe connection: flange according to ISO 7005-2.
• Body: EN-GJL-250 (GG 25) with protective coating; closing element, stem and seat in stainless steel; stem seal: PTFE V-ring.

Permissible mounting position: from vertical to horizontal in relation to the stem; installation with the stem pointing downwards is not permitted. Maximum differential pressure and closing pressure depend on the installed globe valve actuator.
