Cast Steel Low Pressure Check Valve can come with a butt weld or flanged end. The bolted bonnet is made up of a cast iron steel material. The valve sizes range from 2 inches to 24 inches and the pressure classes vary for the Cast Steel Check Valve from 150lbs to 900lbs with pressure numbers ranging from PN10 through PN150. The materials used can be WCB, WC6, WCC, DF8, CF3 and so on. The manufacturing standards of the valves are BS 1868 and DIN 3840. The flange dimensions of the cast steel stop check valve has standards such as ASME B16.5, ASME B16.47 and so on. These regulate the dimensions and sizes of the valves.

High Flow Low Pressure Check Valve
The face to face standards vary as ASME B16.10, DIN3202 and so on. The valves also have different pressure test standards according to the API1598 and other standards. There are fire safety test under the API 607 standard. The cast steel swing check valve class 150 is a low pressure class valve that can operate under low pressure applications. The metal to metal seating is fitted with butt welding or flanged ends. The application of the valves range in chemical, petrochemical, onshore and offshore drilling, oil and gas and other applications. The Cast Steel Pressure Check Valve is preferred due to the low cost, high efficiency and the selective dimensions.
