1" Medium Flow Anti-Siphon Valve
with 1" PR RBY Filter.
Complete, two-piece Control Zone Kit includes the field-proven ASVF valve which has an atmospheric vacuum breaker for backflow prevention and an IAPMO rating.
This PR Filter kit provides 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.
Pressure Loss Chart
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.
