FIRŠT DIVERTING VALVES3-way vertical brass valves with Clip system

FDV 530C

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).

■ Two types of connections are avaliable: external threads (FDV 532C) and compression fittings (FDV 533C).

OPERATIONFIRŠT FDV 532 and 533, 3-way diverting/changeover brass valves are intended for use in heating (solar, remote, house-heating etc.) and cooling installations, especially in heat pumps.

Valves are suitable for long-lasting operation because of special sealing construction. Small rotation torque of the valve minimizes of valve blocking.

Valves can be equipped with series 9000 actuators which allow high regulating accuracy and easy installation with one-click CLIP system.

MAINTENANCEValves require no maintenance. The installation of suitable strainer is recommended.
