BALL CHECK VALVES
(1/2"-4")

     DESIGN ADVANTAGES

  • Full-length body guide ribs allow maximum flow, minimize turbulence, and prevent ball sticking and chatter.
  • True Union design facilitates ease of installation and maintenance.
  • Can be mounted vertically or horizontally.
  • Less than one (1) psi to open.
  • Requires only 3 - 5 psi (depending on size) to close down tight.
  • Seats and seals are easily replaceable.
  • Optional PVC screen assembly converts standard ball check to foot valve.
  • Available in socket, threaded, or flanged (ANSI B16.5 class 150)

TVI BALL CHECK VALVES (1/2" - 4")

DESIGN SPECIFICATIONS
Thermoplastic Ball Check Valves (1/2" - 4") are of all thermoplastic construction. Body has full length ribs for maximum flow, minimum pressure drop, and to eliminate ball sticking and chatter. Ball is of solid thermoplastic material. Seat is full circle and resilient. A molded gasket seal and seat enlarges seating surface and facilitates maintenance. Valves require less than one (1) PSI to open and 3 -5 PSI to close drop tight. Valves are capable of installation in either vertical or horizontal pipe run. Valves are readily adaptable for foot valve service with the addition of a screen assembly. Materials of construction shall be as follows: (select as required for service)
