The brass regulator should be used in applications where house pressure is over 90 PSI. It can handle up to 400 PSI and is adjustable from 25-75 PSI. The direct fill link would then be connected downstream to bring the pressure down to the required range.
Excessive pressure can cause valves to close prematurely. Insufficient pressure will cause the cells to fill more slowly and will delay closing. We offer a variety of pressure regulators to assist in controlling house pressure.
Since municipal water supplies vary in static pressure from very low to very high, we recommend filling through our delivery system that has a built in regulator to drop the static pressure at the connector down to 10 PSI.
