CLA-VAL series 90 : Downstream Pressure Control
CLA-VAL 91-01 : Pressure Reducing Valve with non-Return Feature Control
The CLA-VAL 91-01 is designed to reduce a high pressure (P1) and, when a pressure reversal occurs (P2 > P1), to prevent backflow through the valve.

Typical backflow occurs when the valve is installed on a pipe line linking two separate distribution systems and upstream system pressure P1 drops.

Feeding lines to high-rise buildings need also check features to prevent reverse flow.

Included accessories:
• Valve position indicator X101
• Gauge cock CSA-12, Rp 1/2" (upstream & downstream)
• Pressure gauge [0-16 bar] & [0-16 bar]
