HORIZONTAL SWING CHECK VALVE & WITH SPRING ASSIST
(3/4"-8" Flanged)

             
Design Advantages
         

• Lowest pressure drop compared to other check valve designs.

    • Can be installed in either vertical or horizontal piping system.

    • Minimal required back pressure to fully seat disc.

    • No metal internals to prevent the possibility of corrosion.

    • Full faced seat for drop tight shut-off.

    • Stainless steel external fasteners.

    • Easily modified for spring assist option.

    • Designed to fit between ANSI B16.5 Class 150 flanges.

Design Specifications
                 

Thermoplastic Swing Check Valves 3/4"-8" flanged design shall employ molded thermoplastic body, disc assembly, bonnet, and shaft. Metal internals are not acceptable. Valves have a full faced disc seal. Valves require low back pressure for drop-tight seating. Valves are of low pressure drop design. Body has a full open disc stop to prevent over travel and insure proper closing action. Bonnet is full gasketed and fastened using stainless steel hardware. Valves are top entry design for ease of maintenance. Valves are suitable for vertical and horizontal installation. Flanged ends are designed for installation between ANSI B16.5 Class 150 flanges. Materials of construction shall be as follows: (select as required for service)

 

Body/Bonet

PVC,CPVC, ASTM D-1784
PP, ASTM D-4101
PVDF, ASTM D-3222

 

Disc Assembly / Shaft

PVC, CPVC, ASTM D-1784
PP, ASTM D-4101
PVDF, ASTM D-3222
For superior corrosion resistance and added tensile strength ~ Internals parts are PVDF

 

Seat/Seal

EPDM,Ethylene propylene diene monomer
Fluorocarbon, Viton® (DuPont Performance Elastomers)
Fluorel (3M Corp.)
PTFE (Polytetrafluoroethylene), Teflon® (DuPont Performance Elastomers)

 

NOTE: Can be easily modified for spring assist operation.
