  • BF series low pressure back pressure valve

    The back pressure valve is generally used for two purposes: 1: The back pressure valve is used to prevent the liquid from flowing (or siphoning) under the action of gravity. At this time, the pressure of the liquid is usually greater than the pressure of the liquid itself. Liquid self-flow, can choose back pressure valve with pressure greater than 0.02MPa, generally choose 0.1MPa. 2: The back pressure valve is used to stabilize the flow of the pump. If the flow of some pumps varies greatly with pressure, a back pressure valve can be set at the outlet of the pump to stabilize the output flow of the pump.

  • Low pressure back pressure valve

    Back pressure valve Back pressure valve generally has two purposes: 1: Back pressure valve is used to prevent the liquid from flowing (or siphoning) under the action of gravity. At this time, generally, the pressure greater than the liquid itself can be used. For example, to prevent the liquid level from 2 meters. The liquid in the tank is self-flowing. A back pressure valve with a pressure greater than 0.02 MPa can be selected. Generally, 0.1 MPa is sufficient. 2: The back pressure valve is used to stabilize the flow of the pump. If the flow of some pumps varies greatly with pressure, a back pressure valve can be set at the pump outlet to stabilize the output flow of the pump.
