The stainless steel swing check valve is available in sizes 1/4" - 3" with 200PSI working pressure and PTFE packing. Threaded (NPT) end connections. Swing check valves prevent reversal of flow through pipe lines. They offer low resistance to flow and are particularly suited to low velocity service and can be installed in horizontal or vertical, upward flow, piping. They are opened and sustained in the open position by the force of velocity pressure, and closed by the force of gravity. Seating load and resultant tightness is dependent upon back pressure. The disc and associated moving parts may be in a constant state of movement if the velocity pressure is not sufficient to hold the valve in a wide open and stable position. Premature wear and noisy operation or vibration of the moving parts can be avoided by selecting the size of check valve on the basis of flow conditions.
German production equipment&Product Features
RUIDU company adopt the German production equipment and improve efficiency to 70% -80%. Our company laid a good foundation for the future because of sophisticated equipment and serious attitude.
Casting Steel Swing Check Valve realizes its opening and closing through the internal-installed swing hinge with the function of disc gravity and the pressure foce of meduim.The disc is easy to be manufactured, and its sealf-aligning sealing face could meet the sealing face of seat to get a good sealing performance when valve is closed.
