Pump protection valve DN 150 PN 10/16

1706150000 Pump protection valve DN 150 PN 10/16

Product attributes

The main valve is a hydraulically operating diaphragm valve. The work energy is the inherent medium.
Most valve types operate purely hydraulically without any foreign energy.

The pump protection valve opens with a time delay after the pump is started up. Consequently the network pressure increases to the full pump pressure before the valve opens. With a controlled stopping of the pump, the valve closes before the pump stops. The opening and closing speeds can be set on the throttle non–return valve. In the event of a power failure, the installed hydraulic return–flow function prevents a backflow to the pump (the valve closes).

To calculate the dimensions of the valve please refer to the following information:
Maximum and minimum inlet pressure (static and dynamic pressure ratios)
Existing counterpressure
Required flow rate, pump capacity
Maximum permissible loss of pressure
Voltage information for the solenoid valve
Available line diameters and lengths
Construction of the valve (straight or angle design)
The controller is to be provided by the customer.
For the calculation basis, information on the loss of pressure and the characteristic values of the valve, please refer to the end of Chapter E.
