Working Mechanism

  • During system flow conditions, the fluid movement / pressure forces the disc to open position, allowing 100% (unrestricted) fluid flow.
  • Under reverse flow conditions, the valve disc returns to the closed position, preventing reverse flow completely.

Features

  • Val-Matic 512A Swing-Flex check valve features non clog design to ensure that the flow area is unrestricted for maximising flow rate and lowering unwanted headloss.
  • It features fusion bonded epoxy coating on both exterior & interior surfaces for preventing any chances of fluid contamination. Additionally, this coating also minimises wear against abrasive conditions & harsh industrial environments.
  • This 12-inch check valve features a domed access port that allows for easy removal of the disc without removing the valve from the fluid line.
  • It offers quick & easy maintenance while minimising downtime.
  • It has a synthetic reinforced disc that features an O-ring type, ensuring positive seating at low and high pressures.

Standards and Approvals

  • NSF/ANSI 61
  • NSF/ANSI 372
