The Flomatic 5620 1/2" 193D plastic foot valve is a compact, corrosion-resistant valve designed to help maintain pump prime, prevent backflow, and keep debris out of suction lines. It features an acetal body and strainer, a Nylon 11 poppet, a stainless-steel spring, and a Nitrile (Buna-N) seal. Rated for a maximum working pressure of 150 psi and a maximum temperature of 140°F (60°C).

Specifications:

Max Pressure: 150 psi

Max Temperature: 140°F (60°C)

Body: Acetal

Poppet: Nylon 11

Seal: Nitrile (Buna-N)

Spring: Stainless steel

Connection: 1/2" Female NPT

Operation: The spring-loaded poppet closes quickly to reduce reverse flow and help maintain system prime, while the integrated molded acetal strainer helps prevent larger debris from entering the suction line.

Construction: The 193D design combines a one-piece acetal body and strainer with a non-metallic poppet and stainless-steel spring to provide a lightweight, corrosion-resistant solution for small suction lines. The streamlined internal geometry supports smooth flow with relatively low head loss through the valve.

Applications: Residential and light commercial wells, irrigation systems, water transfer, and general utility pumping systems.
