Features

• The ACV ratio reducing valve maintains a fixed ratio between upstream and downstream pressure: as inlet pressure varies, the outlet pressure varies proportionally
• This is particularly useful on systems where demand patterns cause large upstream pressure fluctuations, as it avoids the very low outlet pressures that a fixed-set-point PRV would deliver at low inlet pressures
• Fully hydraulic, no external power required

Notes

• * L dimension given is for 16bar valves. For higher pressures L is longer by the increased flange thickness.

Description

Fixed-ratio PRV for network pressure management. The ACV ratio reducing valve maintains a fixed ratio between upstream and downstream pressure: as inlet pressure varies, the outlet pressure varies proportionally. This is particularly useful on systems where demand patterns cause large upstream pressure fluctuations, as it avoids the very low outlet pressures that a fixed-set-point PRV would deliver at low inlet pressures. Fully hydraulic, no external power required.
