It is used to prevent overheating due to shutoff operation of the pump and to keep the pump discharge pressure constant.
What is a back pressure valve?
Refers to the primary pressure control valve. A regulating valve that discharges fluid in response to changes in the force on the primary side in order to maintain the fluid pressure on the primary side at a certain constant pressure.
What is the purpose of the water fall prevention valve?
