Please note:

1. Specific Structures & main dimensions see drawings.

2. The action principle is when the handle drives the stem & ball with 90° rotation to open & close valves. When handle is parallel with body channel, valve is opening. On the contrary, when the handle is perpendicular to body channel, valve is closed. The locating plate can do the limit control.

3. The seat is double sealing and soft sealing. These’re very convenient to replace, and the technology is also very simple.

4. Direct mounting pad also called Top Mountain Flange, is suitable to this ISO 5211 Standard.

5. Torques are actual and based on maximum differential low temperature service, without safety factors.
