TL-440 electric rotary ball valve flange ball valve is a 90 degree, good sealing performance, large flow capacity, small flow resistance, simple structure, convenient maintenance, equipped with TL series actuator, in addition to the control of gas, liquid and other media, can also control, widely used in chemical, petroleum, metallurgy, power plant, refrigeration etc. Field.
1.fluid resistance is small, even if it is reduced, the resistance of the fluid in all the ball valve is also the smallest
2.thrust shaft bearings to reduce the friction torque of the stem, can make the long-term operation of flexible stem
3.valve seat sealing performance is good, the use of PTFE sealing material, the structure is easy to seal, and the sealing performance of the valve with the increase of the medium pressure
4.The stem seal is reliable, because the stem only do rotational movement and do not lift movement, the stem of the sealing material is not easy to damage to make sure a long service life.
