Belimo H720S - 3-way globe valve

Belimo H720S – 3-way globe valve

Flanged valve for closed water systems, designed for continuous control on the water side of ventilation and heating systems. It can operate as a mixing valve A+B to AB or as a diverting valve AB to A+B. In diverting mode, the permissible pressure values are lower than in mixing mode.

Key features

• DN 20, PN 16; Kvs 6.3 m³/h.
• Flanged connection in accordance with ISO 7005-2.
• Medium: water or water with a maximum of 50% by volume 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; B – AB max. 1% of Kvs.
• Stroke: 20 mm.
• Body: EN-GJL-250 (GG 25); closing element, stem and seat in stainless steel; stem seal: PTFE V-ring.
• Permissible installation position: from vertical to horizontal relative 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.
