Plastic Swing Check Valves
|3" to 8", PVC and PPL|
Twice the Temperature/Pressure Rating of Other Plastic Swing Check Valves: Hayward swing check valves have up to twice the temperature/pressure rating of other plastic swing check valves, and can replace metal valves in many applications. Compare the temperature/pressure rating of Hayward Swing Check Valves to others and see the difference.
Unique Two-In-One Seat Design: Swing check valves are often used with slurries or other liquids that can damage the valve seat. A damaged seat in an ordinary swing check results in a useless, destroyed valve. But not with Hayward Swing Check Valves. They feature a unique two-in-one seat design that doubles the valve's service life. The valve body is constructed from two identical halves. If one seat is damaged, simply re-position the clapper so that it seats against the other body seat. Then reverse the valve in the pipeline. Now the valve is again ready for service.
Built in O-Ring Flange Seals: Hayward Swing Check Valves are furnished ready for installation with two built in o-ring flange seals. There is no need to purchase additional, expensive flange gaskets.
Self-Aligning Clapper Seal: Bubble tight checking, with a minimum of only 3 psi back pressure, is assured with Hayward's rugged, self-aligning clapper seal design.
No Corrosion: Because of their all plastic construction Hayward Swing Check Valves will never stick or jam as a result of rust or corrosion. And they can survive corrosive environments and harsh weather conditions, places where a metal check valve has to be painted or epoxy coated just to survive.
