The structural design of manual gate valves is centered on achieving reliable cutoff of medium flow. Its main components and structural characteristics are as follows, which can be analyzed in detail from three parts: core components, drive mechanism, and sealing system:1、 Core structural component...

The working pressure and temperature range of high-temperature and high-pressure gate valves need to be determined based on specific materials, structural design, and industry standards. The following are common ranges and explanations:1、 Range of work pressure1. Conventional pressure levelNational...

Compared with other valves, manual gate valves have the following advantages and disadvantages:advantageLow fluid resistance: When the manual gate valve is fully opened, the gate opening height is large, and the fluid can pass through the valve without obstruction. The flow channel is almost unobstr...

American standard gate valves refer to gate valves designed, manufactured, and inspected in accordance with relevant American standards such as ASME and API. It follows American standard specifications in terms of structure, size, materials, and performance, and is commonly used in industries such a...

The pressure rating of American standard gate valves is divided according to the relevant standards of the American National Standards Institute (ANSI)/American Society of Mechanical Engineers (ASME), mainly including the following common pressure ratings:Class 150: This is a common pressure rating...
