Small bronze swing check valve with threaded ends

Value Brand

Value Brand 1/4" Swing Check Valve Bronze PTFE 300 psi 4 gpm

SKU CH-HG7R-WW3EE

Bronze swing check valve with PTFE seal handles 300 psi water pressure and 4 gpm flow in horizontal or vertical mounting

  • Size1/4"
  • TypeOther
  • Bronze body resists corrosion in water systems
  • PTFE seal handles temperatures from -20 to 406 °F
  • 300 psi water rating supports high-pressure lines
  • 750 to 1.000 psi cracking pressure opens with minimal flow
  • 4 gpm full-flow capacity maintains efficient throughput

1/4" Bronze Swing Check Valve

The valve uses an inline swing mechanism with a bronze body and PTFE seat to provide full flow in a 1/4 inch FNPT connection. It is rated for 300 psi water pressure and 150 psi steam pressure with a cracking pressure between .750 and 1.000 psi.

Suits low-pressure water

Installers who require a larger pipe diameter, a different connection type such as solder or press-fit, or a cracking pressure outside the .750 to 1.000 psi range should select another valve. The bronze construction also makes it unsuitable for systems requiring lead-free materials.

Cracking pressure .750 to 1.000 psi

This narrow spring range determines whether the disc opens reliably at the system's minimum flow condition. If the application demands a higher or lower opening threshold, the valve will not function as intended.

Questions about this item

How much heat can the bronze body and PTFE seal handle in continuous service?

The valve is rated for a maximum temperature of 406 °F and a minimum of -20 °F, so the materials withstand sustained hot-water or steam lines within that range.

What pipe threads must my existing plumbing have to connect this valve?

It uses 1/4-inch FNPT female threads on both ends, so the mating pipe or fittings need matching 1/4-inch MNPT male threads.

Will the 0.750-to-1.000 psi cracking pressure let gravity-fed tanks open the valve reliably?

Yes, the low cracking pressure of 0.750 to 1.000 psi allows the swing disc to open under very light head pressure typical of gravity-fed systems.
