Advantage

In water systems, the valve is installed to connect the heads of water supply and return, to keep the predetermined differential pressure between the supplying and returning heads, so as to maintain a minimum flow rate through the protected equipments (e.g. chiller, boiler, etc) for avoiding damages due to insufficient flow or pressure surge.

Describe

Features:

Normal closed. The valve opens when the downstream pressure exceeds the set limit, to keep the predetermined differential pressure.

Automatic operation. Electrical actuators are not required.
