Description:
- Spring check valve size: 3/4" 、1/2 female to female NPT connections
- Check valve body material:Stainless steel 304, cracking pressure: 4.5 psi
- Check valve working temperature: -60℉ to 450℉(-51℃ to 232℃); seals:NBR; max pressure:1000 Psi for water, oil, gas (WOG1000)
- H12W check valve has high precision, beautiful appearance, small shape, spring device, vertical and horizontal installation, etc. It mainly adapts to prevent back flowof the medium in the pipeline system.
- Vertical check valve is 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, bio-diesel, fuels and alcohols.
-
- It has short structure, small volume and light weight.
- The valve flap is closed quickly and the water hammer pressure is small.
- The flow path is smooth, the fluid resistance is small; the action is sensitive, and the sealing performance is good.
- Easy to install, can be installed in the horizontal and vertical lines of the pipeline.
- The valve plate adopts the design of adding two torsion springs on the dual plate to make the valve plate self-closing.
- Due to the fast closing action, it can prevent the medium from flowing backward and eliminate the strong water hammer.
