Complete, two-piece Control Zone Kits include the field-proven ASVF valve which has an atmospheric vacuum breaker for backflow prevention and an IAPMO rating.
These PR Filter kits provide on/off control, filtration, and pressure regulation with only two parts; so there is less chance of leakage at the connections, both at installation and over the life of the system.
In order to supply 40 psi (2.8 bars) outlet pressure, additional pressure is needed at the inlet since there is some pressure loss from water flowing through the kit. The amount of pressure loss depends on the flowrate.
The charts below list the minimum inlet pressure required to supply 40 psi (2.8 bars) of outlet pressure.
|Minimum Inlet Pressure for 40 psi Outlet Pressure|
|Flow (gpm)||Inlet pressure (psi)|
|Minimum Inlet Pressure for 2.1 bar Outlet Pressure|
|Flow l/m||Inlet Pressure (bar)|
