Belimo EXT-H632XP-650 - pressure-independent 2-way globe valve

Belimo EXT-H632XP-650 – technical data

2-way globe valve with a mechanical differential pressure regulator and a control valve designed for a Belimo actuator. The regulator compensates for pressure fluctuations and maintains a constant differential pressure across the control valve. Correct flow regulation requires maintaining the minimum differential pressure.

• Nominal diameter: DN 32; flange connection according to EN 1092-2; PN 25.
• Nominal flow V'nom: 1.8 l/s (6.5 m³/h); theoretical Kvs value: 12.5 m³/h.
• Medium: water or water with max. 30% vol. glycol; medium temperature: 5...140°C [41...284°F].
• Maximum differential pressure across the control valve: 1500 kPa. To prevent cavitation, ∆pmax must be calculated in accordance with the design notes.
• Flow characteristic: equal percentage; permissible leakage: max. 0.05% of the Kvs value.
• Stroke: 13 mm; body: EN-GJS-400-18-LT (GGG 40.3).
• Permissible mounting position: vertical to ±45° relative to the stem.

Maximum flow V'max is set using the adjustment ring on the valve neck. Observe the flow direction indicated by the arrow on the body.
