2”-42” SERIES 1900 FOOT VALVE
OPERATION, MAINTENANCE AND INSTALLATION
INTRODUCTION
This manual will provide you with the information to properly install and maintain the valve to ensure a long service life. The Series 1900 Foot Valve is ruggedly constructed with bronze or stainless steel trim to give years of trouble free operation. The valve should be installed in a vertical suction pipe carrying clean water.
The Foot Valve is designed to open fully to provide flow in the forward direction and close rapidly upon flow reversal. The valves are used to prevent reverse flow and maintain the prime on pumps. The size, cold working pressure, and model number are stamped on the nameplate for reference.
This valve is not intended for fluids containing suspended solids such as wastewater. For wastewater and other high turbidity applications, use Val-Matic Series 500 Swing-Flex
CAUTION: This valve is not intended for
fluids containing suspended solids or hazardous fluids.
RECEIVING AND STORAGE
Inspect valves upon receipt for damage in shipment. Unload all valves carefully to the ground without dropping. When lifting, the valve should be secured by the body and never lifted by the basket or trim.
The valves should remain crated, clean and dry until installed to prevent weather related damage. For long term storage greater than six months, indoor storage is recommended. Do not expose the resilient seat to sunlight or ozone for any extended period.

FIGURE 1. FOOT VALVE WITH INLET SCREEN
DESCRIPTION OF OPERATION
As shown in Figure 1, the valve consists of a body, a disc, and a seat with a resilient seal. The valves are designed to prevent reverse flow and maintain a flooded suction when installed at the foot or end of the suction piping. The resilient seal provides drop­tight shutoff and the basket prevent debris from entering the valve and piping system.
The seat and seal are rigidly held in the bottom of the valve. As the flow enters the valve from the bottom, the disc is lifted by the flow and guided to the open positions by bushings in the body. Upon pump shut down, the return flow and weight of the disc close the valve rapidly and maintain the pump prime.
