VFPIP15-780 VFPIx - Pressure independent control valves

Pressure independent control valves, DN15-25, 2.7 mm stroke. The valve is a combined differential pressure regulator, flow limiter and equal percentage control valve with full stroke and authority. The pressure independent control valves are suitable for constant or variable temperature systems and can be used as constant flow limiters in constant volume systems (with no actuators), or as pressure independent control valves in variable volume systems (with actuators).

The VFPIP / VFPIM / VFPI valves DN15-25 are intended to be used together with ITK's SE1Cxxx or SEZ2 actuators.
