Belimo EXT-H632P-650 - 2-way pressure-independent globe valve

Belimo EXT-H632P-650

2-way globe valve independent of pressure changes, with a mechanical differential pressure regulator and control valve. The regulator compensates for pressure fluctuations and maintains a constant differential pressure across the control valve. Correct flow regulation requires the minimum differential pressure to be maintained.

Key features

• DN 32, PN 16; flanged connection in accordance with EN 1092-2.
• V'nom 1.8 l/s (6.5 m³/h); theoretical Kvs value: 12.5 m³/h.
• Stroke: 13 mm; Sv min.: 20.
• Medium: water or water with a maximum of 30% vol. glycol; medium temperature: 5...140°C [41...284°F].
• Maximum differential pressure across the control valve: 1000 kPa. To prevent cavitation, ∆pmax must be calculated in accordance with the design notes.
• Flow characteristic: equal percentage; allowable leakage: max. 0.05% of the Kvs value.
• Body: EN-GJL-250 (GG 25), with protective coating.
• Installation in a vertical position with an inclination of up to ±45° relative to the stem; observe the flow direction indicated by the arrow on the body.
