The Model 720-20 Pressure Reducing Valve with Check Feature is a hydraulically operated, diaphragm actuated control valve that reduces higher upstream pressure to lower constant downstream pressure regardless of fluctuating demand or varying upstream pressure. The check feature prevents reverse flow through the valve.

Typical Product Applications
Cost Effective Pumping
One zone of a distribution network has two supply sources. Setting the Model 720-20 Pressure Reducing Valve with Check Feature slightly higher than pump pressure, ensures pumping only when pressure provided from the network is insufficient. The Model 720-20:
- Protects the zone from excessive network supply pressure
- Saves energy and lowers costs by off-hours pumping
