VR series filling valves are composed of pressure reducer, filter on the inlet side, cut-off cock and check valve. They must be installed on the delivery pipe to the closed circuit heating system so the system pressure remains steady at the set value and water is filled whenever needed.The stainless steel filter and check valve are built in the body. VR filling valves are available with or without pressure gauge, with brass or nylon glass cap.

Max pressure upstream of the valve:14 bar
Pressure downstream of the valve: 0.4 to 4 bar
Factory set pressure: 1.5 bar
