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
