Features
- The A20B is a high-flow pressure reducing valve for trunk main and bulk supply duty where the A200 body is undersized for the required flow capacity
- The enlarged body and flow passages accommodate higher flow rates at low headloss, making it suitable for primary pressure management stations serving large distribution zones
Description
The A20B is a high-flow pressure reducing configuration of the A900 main valve body for trunk main and bulk supply duty where the standard A200 body is undersized for the required flow capacity. The enlarged body and flow passages accommodate higher flow rates at low headloss. Fitted with a P200 reducing pilot, the control behaviour is identical to the A200. Used at primary pressure management stations serving large distribution zones.
