Pneumatic PTFE lined Ball valve Q641F46

       Pneumatic PTFE lined Ball valve Q641F46 as is the use of fluorine plastic lining, and combined with a new rod Ball band structure, coupled with its unique elastic lip Seal seat structure, it has the advantage of ordinary Ball valve, Pneumatic PTFE lined Ball valve Seal can have a high performance and low operating torque over a wide temperature range and larger pressure changes. Pneumatic PTFE lined Ball valve can be used for switching or adjustment purposes, Pneumatic PTFE lined Ball valve for a variety of industrial pipes and transporting liquid gas (including steam), can work well in a variety of acids, bases, salts and other strong Corrosive medium in. Pneumatic PTFE lined Ball valve provide maximum flow, it can be used for cleaning or sweeping line isolation conveying pipeline. 

Product features: 
Fluid resistance, Ball valve is the smallest of all valves fluid resistance, even reduced diameter Ball valve, the fluid resistance is quite small. Valve rod thrust bearing to reduce the friction torque, can balance the long-term operational flexibility Valve rod good valve seatSeal performance, the use made of Teflon and other Materials seal ring, the structure is easy to seal, Ball valve and valve sealing capability with the addition of the medium pressure increases. valve rodSeal reliable, since only valve rod for rotation motion without doing down movement, Valve rod of Packing Seal not easy to destroy, and the Seal of the additional capacity as the pressure medium increases. PTFE and other Materials with good self-lubricating, low friction losses and Ball, help Ball valve long life.
