Set of two Danfoss FHF-BV ball valves designed for connecting an underfloor heating manifold to the heating system. The valves allow reliable shut-off of the flow and return of the heating water during servicing, filling or venting of the system. One valve is marked with a red handle (flow) and the other with a blue handle (return), making identification easier during installation and operation.

The product is an accessory for Danfoss SSM series manifolds for wet underfloor heating systems. The 1" (G 1") thread ensures direct compatibility with these manifolds without the need for reducing adaptors. Each valve includes a detachable union connection and a provision for thermometer installation to monitor the flow or return temperature.

The pack contains 2 x 1" ball valves — one with a red handle (heating water flow) and one with a blue handle (return). Each valve is equipped with a detachable union connection and a thermometer port.

Features

The valves are made of brass and provide full-bore shut-off of the circuit. The ergonomic lever handle enables quick and easy operation. The colour coding of the handles (red / blue) corresponds to the standard flow / return designation. The integrated thermometer port allows installation of the Danfoss FHD-T temperature sensor (088U0029) for continuous monitoring of flow and return temperatures.
