Structural form:
The series ball valve is different from ordinary ball valves and is a high-reliability ball valve with a fixed axis. The ball of an ordinary ball valve can drift axially. The ball is pressed against the ball seat seal by the pressure of the medium in the valve. When the working pressure is high, the pressing force between the ball and the ball seat seal on one side is very large, and there is even a gap between the seal and the ball on the other side. in a state of separation. The ball of the series ball valve is a ball seat seal that cannot move axially and is pressed against the ball by the force of the spring. No matter how high the pressure of the medium in the valve is, a moderate pressure is always maintained between the ball seat seals on both sides and the ball.
Features:
dLong service life:
Because the ball seat seal bears little extrusion force from the ball, the friction is small during the rotation and the seal is not easy to wear.
d High reliability:
When the ordinary two-way high-pressure ball valve is closed at high pressure, only the ball seat seal on the pressure side plays a sealing role, while the ball seat seals on both sides are pressed tightly by the force of the spring. The ball always plays a sealing role at the same time, so the reliability is high.
d Short wrench:
Since the ball seat seal bears the extrusion force of the ball, the small torque required by the ball during rotation is small, so a short wrench can be used.
d Any end of the three-way valve can be used as a high-pressure end:
The ball seat seal of the three-way valve is much better under pressure than an ordinary three-way valve. Any end can be used as a high-pressure end.

ball seat seal can be used for
high pressure:
It is widely used in medium and low pressure due to its very good corrosion resistance, wide temperature range and low friction coefficient. Ball valves, however, cannot be used for ball valves with ordinary floating ball cores whose working pressure is greater than r due to their insufficient resistance to extrusion. However, ball valves with a series of fixed ball cores can be used in working conditions of r due to the small extrusion force on the seal. .
