Belimo H679SP - 2-way globe valve DN 80

Belimo H679SP – 2-way globe valve

This valve with a partially pressure-balanced plug is designed for closed water and steam systems in non-critical applications, and for water-side control in ventilation and heating systems.

Key features

• Nominal size DN 80; nominal pressure PN 16; flanged connection.
• Kvs 90 m³/h; stroke 18 mm.
• Fluid: water and steam (Δp/P1 <0,4), and water with up to 50% vol. glycol.
• Fluid temperature: 5...150°C [41...302°F]. Pressure guidance: 120°C up to 1600 kPa; 150°C up to 1400 kPa.
• Equal-percentage characteristic, optimised over the opening range.
• Permissible leakage: max. 0,05% of the Kvs value.
• 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 in relation to the stem; installation with the stem pointing downwards is not permitted. Observe the flow direction indicated by the arrow on the body. Maximum differential pressure and closing pressure depend on the actuator used.
