Belimo H750S - 3-way globe valve

Belimo H750S – technical data

3-way globe valve with a flanged connection. 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.

• Nominal diameter: DN 50; nominal pressure: PN 16.
• Flow coefficient: Kvs 40 m³/h; stroke: 20 mm.
• Medium: water or water with max. 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 the Kvs value; B – AB max. 1% of the Kvs value.
• Body: EN-GJL-250 (GG 25); plug, stem and seat: stainless steel; stem seal: PTFE V-ring.
• Pipe connection: flange in accordance with ISO 7005-2.

Installation is permitted from vertical to horizontal in relation to the stem; installation with the stem pointing downwards is not permitted. Maximum differential pressure and close-off pressure depend on the actuator installed.
