Product introduction:
Gate valve AGM board valve or gate valve, a valve is the most widely used. Gate through the gate to open and close the control valve, gate perpendicular to the flow direction, changing the relative position between the gate and the seat can change the channel size.

American Standard valve is used as cut-off media, the flow through the fully open, then the pressure medium to run with minimum loss. API gate valve Flanged steel gate valve usually do not apply to the regular opening and closing, and maintain the gate fully open or fully closed condition, does not apply to the use as a regulator or throttle. For high-speed flow of medium, American Standard valve gate open in local conditions can cause the gate vibration, and vibration may damage gate and valve seat sealing surface, and cutting medium will suffer erosion gate. From a structural form, the main difference is that the sealing component used in the form of.

Application range:
Flanged steel gate valves for American Standard ANSI Class150 ~ 600, PN2.0 ~ 16.0MPa, JIS10 ~ 20K, temperature -29 ~ 425 ℃( carbon ) and -40 ~ 500 ℃( stainless steel ) of a line, used to cut off or connected to medium in pipelines. Through the use of different materials, steel American Standard valve can be applied to water, steam, oil, nitric acid, acetic acid, strong oxidizing medium and urea and other media. Manual, bevel gear drive and electric etc..

Structural characteristics:
1, small fluid resistance, the sealing surface by the erosion of small and medium Chong brush.
2, American Standard valves open and close more effort.
3, media flow unrestricted, non-spoiler, do not reduce the pressure.
4, a simple shape, structure, short length, good manufacturing process, wide range of application.

Standard Specification for:
Design and manufacturing standards: API 600
The structural length standard: ASME B 16.10
The connecting flange standard: ASME B 16.5
Pressure - temperature rating: ASME B 16.34
Testing standard: API 698
