Product details

Product description:

American standard valve is used as a cut-off medium, the entire circulation straight through the full open, this time the pressure loss of medium operation minimum. API gate valve Steel flanged gate valve is usually suitable for not require frequent opening and closing, and keep the gate fully open or fully closed conditions, not suitable for use as regulation or throttling. For high-speed flow medium, American standard gate valve gate in the local open condition can cause gate vibration, and vibration may damage the gate and valve seat sealing surface, and throttling the gate will suffer media erosion. The main difference from the structural form is the form of the sealing element used.


Use and performance specifications

1.1 Uses:

a, This product is mainly used for gas, liquid medium for the hoist pipe, connect or cut off the media flow, does not apply to regulate the flow of media. With a small flow resistance, opening and closing more effort and so on.

b, the scope of application: chemical, petroleum, metallurgy, papermaking, pharmaceutical and other industries.
