"r-square" cast steel swing check valves are used in pipe lines with liquid and gaseous fluids over a wide range of line pressures and temperatures
"r-square" swing check valves body designed for strength to meet operating conditions and contoured to minimize erosion and resistance to flow.
the disk is opened and sustained in open position by the velocity pressure of the fluid and closed by the force of gravity, seating load and resultant tightness is aided by back pressure in the line.
the body seat ring threaded to the body to avoiding leakage the path between the seat ring and the body. The seating surfaces are ground and lapped.
"r-square" check valve are offered with flange and butt weld ends to bs 1868.
