It maintains a constant back pressure by discharging excess pressure downstream and when the solenoid is activated the valve closes drip-tight. In operation, the valve is actuated by hydraulic line pressure through the pilot control system. When inlet pressure is greater than the control setting, the valve opens. When inlet pressure is equal to the control setting, the pilot modulates the valve, maintaining the preselected back pressure. When inlet pressure is less than the control setting, the pilot system closes the valve drip tight. Changing the pressure setting simply involves turning an adjusting screw on the pilot control. The solenoid control is available in energize to open or de-energize to open models. Back Pressure Maintenance Service A frequent application of this valve is to maintain minimum back pressure in the system while supplying water to a reservoir. The electrode in the storage tank activates the solenoid shutoff feature when the tank reaches a preset level. Electronic Control Service Using a timer connected to the solenoid control of the valve, flow from the high pressure system to the low pressure system can be controlled at certain times during the day. Typical Applications The "D" feature on a vertically installed 6" and larger valve must be horizontally oriented. 58-01 MODEL

Back Pressure Maintenance ServiceA frequent application of this valve is to maintain minimumback pressure in the system while supplying water toa reservoir. The electrode in the storage tank activatesthe solenoid shutoff feature when the tank reaches apreset level.
Electronic Control ServiceUsing a timer connected to the solenoid control of the valve,flow from the high pressure system to the low pressuresystem can be controlled at certain times during the day.
Typical Applications
The "D" feature on a vertically installed 6" and larger valve must be horizontally oriented.

Notes:• For sizes 18 through 36-inches / 450mm though 900 mm, use 50-66 E-Sheet • Many factors should be considered in sizing pressure reducing valves including inlet pressure, outlet pressure and flow rates.• For sizing questions or cavitation analysis, consult Cla-Val with system details.
