About this item

  • Body Material:Stainless Steel 316,200PSI/PN16,ANSI B1.20.1,Includes stainless steel 316 disc and screwed cap
  • Temperature range: -60 to 450 degree Fahrenheit,Suitable for full range of liquids and gas(water, oil, air, gas, light acids/alkali)
  • Working Pressure 200 WOG,Port Types:Female x Female threaded for connecting to male threaded pipes
  • Check valves are used to help direct flow in one direction. The stainless steel bodies and PTFE seals are highly corrosion resistant allowing these check valves to be used with a wide variety of fluids including, but not limited to water, oil, gas, air, light alkali's, acids, biodiesel, fuels and alcohols
  • Swing check valves are for horizontal use only. When fluid pushes on the stopper in the correct direction, it will "swing" open to allow flow. If flow moves in the opposite direction, it will swing shut. The check valve cannot be used in vertical applications as gravity may affect the function of the swinging motion


Product Description

Swing Check Valve

Check Valve

It has a stainless steel 316 disc, screwed cap, and female National Pipe Taper (NPT) connections on both ends. Female NPT threads connect to male threaded pipes, creating a tighter seal than straight threads.

Check valves have two ports and restrict the flow of fluids and other loose materials through a pipe or passageway to one direction. Flow enters through one port and exits through the other, closing when flow reverses or stops.

Check valves are rated by their cracking pressure (the minimum upstream pressure required for the valve to operate), and they are used in various water, gas, air, and steam lines.

Note: Check valves do not create a 100% seal against backflow like a ball valve would. If prevention of backflow is desired, two check valves should be used in series with each other. Any fluid which finds its way past the first check valve is unlikely to have enough pressure to pass through the 2nd.

For use with biodiesel, this check valve will require changing of the NBR seals to a more resistant seal

Package: 1 Pc x Check Valve

Valve leaks. Seal on body not machined properly (see pictures). Very annoying, lost time and money.

This check valve has been used for a wood salt water pool heater. It has not rusted at all so far and is working as expected. Very good product with confirmed good SS316, otherwise other materials would have already rusted.
