Installation

  • When Installed Vertically (or upto 60° angle) check valve close automatically because of centre guided ball.
  • When Installed Horizontally (90° to 60°), the valve close automatically if the back flow related to water is 1.5 – 2.5 m/sec.
  • Full Bore when valve is opened. i.e. Low Pressure Drop condition.
