Typical for applications are: requirement for easy installation, stable and fast-acting control, quiet and service-free operation; PN 16 pressure class; threaded valves; variety of valve construction types; electro-motoric 3P/0-10 V with plug-in connection cables available in different lengths and also in halogen-free versions; combi-valves for energy efficiency in large systems.

The proposed combinations vary in: control quality (valve characteristic); k_VS range; PN class, valve construction, pipe connections.

PN16 threaded valves with equal percentage characteristic and 5.5 mm stroke; k_VS 0.25 ... 6.3 m³/h; 2-port VVP45, 3-port VXP45 and 3-port with bypass VMP45 valves ; external treads ISO 228-1 (flat face) or BS 84 (compression fittings) high control performance; high close-off pressure.
