Under normal conditions, Full lined PTFE butterfly valve can replace the stainless steel valve body. The butterfly plate of the butterfly valve is installed in the diameter direction of the pipe. In the cylindrical channel of the butterfly valve body, the disc shaped butterfly plate rotates around the axis with a rotation angle of 0 °~90 °. When the rotation angle reaches 90 °, the valve is fully open.
Advantages of Full Lined PTFE Butterfly Valve
In order to better adapt to the needs of modern automatic control, the PTFE lined butterfly valve can be equipped with electric. And some of them equip with pneumatic actuators. The operation can be controlled by inputting control signals (4~20mADC or 1~5VDC). In additional, equip with single-phase power supply, which can realize intelligent (regulating) and switching. It has strong function, small volume, light and pleasant, reliable performance, simple matching. And large circulation capacity is also the advantage for it. Especially it is suitable for occasions where the medium is viscous, contains particles, and has fiber properties. TWT Valve manufacturer and supplier always ensure quality production. No matter domestic or oversea customers, our high-performance valves always are worthy to recommand.
Disadvantages of Full Lined PTFE Butterfly Valve
The fully lined PTFE butterfly valve and rubber lined butterfly valve have been widely used in many fields such as petroleum, chemical industry, metallurgy, hydropower, etc. As a component used to realize the on-off and flow control of the pipeline system. In the well-known butterfly valve technology, the sealing form is mostly the sealing structure, and its materials are rubber, PTFE, etc. Due to the limitation of structural characteristics, it is not suitable for high temperature. Certianly it’s also not for high pressure, corrosion resistance, wear resistance and other industries.
Specification of PTFE Butterfly Valve
The full lined PTFE butterfly valve body of MVS PTFE lined butterfly valve is wafer type. The valves are with specifications of ANSI 150 #, PN6, PN10, PN16. It can be operated by hand-lever, manual-gear, pneumatic actuator and various accessories. For related accessories such as positioner, proximity switch box, limit switch, solenoid valve, etc. Our high-performance PTFE lined butterfly valves are ideal for isolating; Controlling the strict performance requirements of wet and dry chlorine and hydrochloric acid.
