Q941F46-16C Electric Fluorine Lined Ball Valve product Description
Q941F46-16C Electric Fluorine Lined Ball Valve produced and sold by Baigang valve group is a rotary ball valve Angle of 90°, excellent sealing performance, flow capacity, flow resistance coefficient is small, simple structure, easy maintenance, long service life, the valve body channel and connecting pipe diameter is equal and into a diameter, several media can flow without loss.With ODL, OHQ and other high-performance actuator, the product is usually used in the occasion of strict sealing requirements, in addition to the control of gas, liquid, steam medium, but also suitable for the control of sewage and containing fibrous impurities medium, widely used in petroleum, chemical industry, metallurgy, light industry, paper making, power station, refrigeration and other work fields.
 
Q941F46-16C Electric Fluorine Lined Ball Valve product Features
 1. Fluid resistance is small, the ball valve is the smallest of all the hair fluid resistance, even a reduced diameter ball valve, the fluid resistance is quite small. 
 2. Thrust bearings to reduce the valve stem friction torque, valve stem can be balanced long-term operation and flexibility. 
 3. Seat sealing performance is good, the seal made of PTFE and other materials, the structure is easy to seal, and the ball valve sealing ability increases with the media pressure increases. 
 4. Stem seal is reliable, because the stem only to do rotary motion instead of lifting movements, the valve stem packing seal is not easy to damage, and the sealing capacity increases with the media pressure increases 
 5. Since the PTFE material has a good Self-lubricating, with the friction loss of the ball is small, helping the long service life of the ball valve. 
 6. Bottom stem and valve stem convex step to prevent the valve stem ejected, if the fire caused the stem seal damage, convex step and the body can also form a metal contact between the valve stem to ensure that the
