Description
The BELIMO H625S + NVF24‑MFT valve‑actuator set offers a compact yet robust solution for controlling water or water/glycol mixtures in HVAC, heating, or chilled water systems. The H625S globe valve (DN 25) with an equal‑percentage flow characteristic helps deliver smooth, proportional flow changes — essential for stable temperature control and energy-efficient operation in building heating or cooling loops.
Paired with the NVF24‑MFT modulating actuator, the assembly provides precise control via standard 0–10 V (or modulating) signals, enabling integration with Building Management Systems (BMS) or automated HVAC controllers. The 20 mm stroke and 800 N force mean the actuator moves the valve cone reliably, even under pressure or flow resistance — giving trustworthy regulation across different loads.
Because the unit is compact and maintenance‑free, it’s well-suited for installations in tight spaces or retrofit projects. The actuator includes manual override (via hex key), so technicians can manually adjust or test valve position during maintenance, commissioning or emergencies. Compared with generic valves or simple on/off actuators, this BELIMO combination delivers smoother modulation, better control precision, longer service life, and lower leakage risk — saving maintenance efforts and ensuring consistent system performance over time.
