Characteristics
FOV are angle-way pressure regulating valves, which have ajustable opening pressure and cover the differential pressure range (AP): 2-8 bar. The valve can be closed manually, e.g. during plant service and have back seating, enabling the spindle seal to be replaced with the valve still under pressure.
The valves are especially designed to prevent fluttering due to low velocity and/or low density. In consequence it is possible to apply the valves with wide fluctuations in capacity demands, i.e. from maximum performance to partload. A flexible O-ring provides perfect sealing over the seat.
