Designed for use in grid systems or any sprinkler system where pressure relief is required. The Adjustable Pressure Relief Valve can be adjusted from 75-175 psi. Adjustment to the desired pressure is achieved with the use of an approved fire sprinkler system pressure gauge. The adjustment cap is "diamond" knurled for easy adjustment. The body is cast bronze* and marked with directional arrows for proper flow indication. The pressure markings on the adjustment cap are for reference only. Use the system gauge for proper relief setting.
*Contains lead. Not for use in water systems intended for human consumption.
The bronze* swing check valve features a full floating clapper assembly that provides for a positive seal each time the valve is cycled. This feature improves the swing check valves ability to “clear” any debris that may be present in the water supply. The seat material is NBR which provides for a positive seal even under light residual pressures.
*Contains lead. Not for use in water systems intended for human consumption.
FPPI ball drips feature two piece brass construction. Their designed use is to prevent moisture accumulation on the "dry" side of fire department connections when used in conjunction with an approved check valve.
