Filling valve, connection GW 1/2 inch / GZ 3/4 inch, adjustment range 1.5-6 bar VF04-1/2E

Filling valve VF 04 is designed for filling and replenishing water in closed heating systems. The valve includes a pressure regulator, check valve, and shut-off valve. The valve design allows for the installation of a manometer to measure and control the pressure on the installation side. Using VF04 prevents damage that may occur due to excessive pressure during system filling.
Application in closed systems:
for heating circuits with a manifold,
consisting of supply from manifolds,
for filling water through a flexible hose, directly to the boiler or to the supply line.
Output pressure adjustable to (maximum): 3 bar
Output pressure adjustable from (minimum): 0.5 bar
