Belimo C220QPT-F - 2-way PI zone valve with measuring ports

Belimo C220QPT-F – PI zone valve

A 2-way pressure-independent zone valve designed for water-side control in ventilation and heating systems. The integrated pressure regulator maintains a constant flow rate for a given valve opening position within a differential pressure range of 16...350 kPa. Measuring ports (P/T) allow the pressure drop across the valve to be measured.

Key features and parameters
