API 594 Cast Steel Low Pressure Wafer Single Plate Swing Type Check Valve

API 594 Cast Steel Low Pressure Wafer Single Plate Swing Type Check Valve check valve is used to cut off or connect the media in various pipelines of Class 150 - Class 300. The valves made of different materials are suitable for various media such as water, steam, oil, liquefied gas, natural...

Product Details

DESCRIPTION:

As an ultra-thin check valve, the purpose of the API 594 cast steel low pressure wafer single plate swing type check valve is to only allow the media to flow in one direction and prevent the direction from flowing. It works automatically, the valve flap opens under the pressure of the fluid flowing in one direction; when the fluid flows in the opposite direction, the fluid pressure and the self-reclosing valve flap of the valve disc act on the valve seat, thereby cutting off the flow. It has five main types: big size check valve, disk check valve, lug type check valve, metal to metal seat check valve and single plate check valve, you can choose freely according to your needs.

DESIGN FEATURES:

  • The structural length is short, and its structural length is only 1/4~1/8 of the traditional flange check valve.

  • Small in size and light in weight, and its weight is only 1/4~1/20 of the traditional flange check valve.

  • The overall structure is simple and compact, and the shape is beautiful.

  • Both horizontal and vertical pipes can be used for easy installation.

  • Smooth flow path and low fluid resistance

  • The sealing performance is good, the valve stroke is short, and the valve closing force is small.
