Product Identity

The Value Brand 10F304 is a bronze swing check valve with a 1 1/4 inch FNPT connection and PTFE seals. It suits plumbing and light industrial systems that need automatic backflow prevention in horizontal or vertical runs.

Interface Limits

The valve operates between 0.750 and 1.000 psi cracking pressure and handles up to 300 psi water pressure or 150 psi steam pressure. Temperature range spans -20 to 406 degrees F, so it cannot serve applications outside those bounds.

Capacity Headroom

Full-flow design delivers 46 gpm through the 3.375 inch body, giving ample headroom for typical residential and light commercial lines. It runs out when flow demand exceeds that rate or when pressure and temperature limits are reached.

Questions about this item

Which size and connection type should I select for a 1 1/4" bronze swing check valve?

The valve is supplied in a 1 1/4 inch size with FNPT x FNPT threaded connections, matching standard NPT pipe threads for inline installation.

What does the 46 gpm full-flow rating mean when the valve is installed in a water line?

At full open the valve passes up to 46 gallons per minute of water with minimal restriction, suitable for typical residential or light-commercial supply lines.

How do the 300 psi water and 150 psi steam pressure limits affect the valve's use in a heating system?

The body handles 300 psi cold water and 150 psi saturated steam, so it can serve in hydronic heating loops up to 406 °F without exceeding its rated pressure ceiling.
