Belimo PI Zone Valve Rp3/4 Kvs0.98 Measuring Ports Flow Limiter C220QPT-F/ZCQ-FL
This is a Belimo 2-way pressure independent zone valve (PIQCV) with a brass housing and EPDM sealing. The bore diameter of the valve is DN 20 and the port size is Rp 3/4 inch with female threads. The integrated pressure regulating valve enables a constant flow volume and achieves a valve authority of 1, regardless of the differential pressure. The flow rate remains constant with each opening position, even in the presence of pressure variations and in the partial load range, ensuring a steady control. Equal percentage flow control is ensured by the special design of the ball. This valve has two measurement ports (P1 and P3) that allow the determination of the total pressure drop across the valve. The differential pressure measurement optimizes the pump setting by reducing the pump head to maintain the minimum required differential pressure (0.16 bar) at the farthest hydronic point. The maximum pressure differential is 3.5 bar (50.8 psi). The valve can operate between 2 and 90 °C (36 to 194 °F). The Kv value of the valve is 0.98 m3/h, equivalent to a Cv-value of 1.13 gpm. The valve is equipped with a flow limiter. The valve is designed for use with the Belimo 3-point or modulating actuator. Installing Belimo actuators on this valve is made easy due to the central bolt design. The direction of flow, indicated by an arrow on the housing, is of utmost importance to prevent damage to the ball valve.
