Intro
POPU Valve: PTFE Lined Diaphragm Valve
The PTFE Lined diaphragm valve adopts a special process to cover the valve body with PTFE, so that each part of the valve cavity can achieve the same corrosion performance.
The product has good throttling characteristics, corrosion resistance and granular media properties, reliable sealing performance, and can be widely used in various corrosive fluids and fibrous and powdery media.

Advantages
1、The diaphragm valve uses compressed air as the power to drive the transmission screw to make the valve core move up and down, and at the same time pull the diaphragm up and down to make it close and open.
2、The valve has compact structure, small size, small fluid resistance and beautiful appearance; The switch has a guide device, low closing torque and long life.
3、Suitable for corrosive, viscous and slurry media.
4、The valve is easy to quickly disassemble and repair, and the replacement of the diaphragm can be completed on site and in a short time.
5、No leakage, can be used for high viscosity and the adjustment of suspended particle media. The diaphragm isolates the medium from the upper cavity of the stem, so there is no packing medium and no leakage.
