The FIRŠT valves FDV 530C are 3-way diverting/changeover brass valves for use in heating (solar, remote,house-heating etc.) and cooling installations, especially in heat pumps. Valves are equipped with series 9000 2P ND actuators which allow high regulating accuracy and easy installation with one-click CLIP System. Actuators are controlled with 2-point signal (SPST) built-in relay module. Zone units can be manually operated with handle and button on the cover.
Valves are available in DN 20 size, with external threads,or compression fittings and are rated PN10.
FIRŠT valves FDV 532C and FDV 533C are designed for use in heating or cooling systems or for use in different heating or cooling devices (e.g. heat pumps, HVAC systems).
