Automatic regulating valve for sustaining upstream pressure and stabilize the downstream pressure.
Applications :
- Water distribution networks
- Irrigation networks
- Supply and protect a low-service network from excessive pressure using excess water from a high-service network, while at the same time guaranteeing a minimum pressure in the high service network.
- Maintain a minimum pressure at a pump outlet and stabilise the pressure in the downstream network.
