Swing check valves have a solid thermoplastic body with a large "flapper". Check valves are used in applications where it is essential to ensure fluid flow passes in only one direction. Check valves can be mounted in vertical or horizontal directions, with the only restriction being a minimum back-pressure required to properly seat the check valve.

Ideal Applications Include:

Tank inlets/outlets; preventing backflow into a pump; one-way mixing; water hammer mitigation; pressure balancing; process intakes,Chemical processing, bleach plants, aquariums, mining, water treatment, landfills, Swimming pools, Power Plant

Advantages

• Materials meet drinking water standard
• 100% pure virgin material, CaCO3 free (Chalk)
• UV resistant powder added
• Can be assembled vertically or horizontally

Design:

• In particular increase the thickness at the end of body for impact resistance strength when suddenly open
• Two plane and the O-ring grooves are by machining, to ensure the combination of surface formation, better sealing
• Improved design on valve rib, at the bottom to reduce weight and greatly increased due to water hammer valve impact resistance and strength
• The abolition of the metal shaft, all to switch to all-in-one plastic structure, increased corrosion resistance
• Buckle fixed valve petal, the elimination of the original way, replacing the two columns of fixed processing errors, and increase the opening angle to reduce the flow resistance
• Sealing surface design is titled 10 degrees, so that it also can use at the level of the installation
• Lock 8 screws the upper and lower body more closely and firmly, under the water hammer, it is difficult deformation, better sealing
