The structural features of Sanitary Butterfly Valve are as follows:
1. Advanced valve seat
The valve seat designed based on years of experience in ball valve manufacturing has a very low friction coefficient and a wide range of applications.
2. Anti-fly structure of valve stem
A relevant step is set under the valve stem, and then installed from the inside of the valve body to the valve stem to prevent the valve stem from flying out.
3. Anti-static function
The anti-static spring set between the ball and the valve body or valve stem can lead out the static electricity generated during the opening and closing process.
4. Fire-resistant structure
The advanced fire-resistant design, after the fire, each leakage part is designed as flexible graphite filler or stainless steel sandwiched with graphite, which meets the fire-resistant requirements very well and also complies with the provisions of API6FA and API607.
5. The connection will not be misplaced
In order to prevent the valve from being malfunctioning, locking holes are set at the fully open and fully closed positions of the switch to ensure that the valve is in the correct position.
