Pneumatic Diaphragm Valve - PFDV

Pneumatic diaphragm valve type PVD is a compact control valve with excellent corrosion resistance, heat resistance and wide application. It has smooth inner wall and low ion precipitation. It is especially suitable for fields with high cleanliness requirements. Different materials can be selected according to different application scenarios to make it more cost-effective.

Easy operation and maintenance
*All plastic appearance structure, beautiful and corrosion resistant
*Miniaturized design, easy installation and maintenance free
*UNF standard flarelink interface thread, with higher adaptability and interchangeability
*The size of mounting plate shall comply with SEMI standard F65-1101

High safety performance
*Comply with FDA 177-1520 / 177-1550 dissolution test requirements
*Triple sealed valve chamber diaphragm structure can effectively prevent leakage
*The drive mechanism is made of fluororesin with high pressure bearing redundancy
*Curved PTFE diaphragm is more ductile and has a long service life

High flexibility
*Wetted material PP natural, PVDF, PFA
*Diaphragm material PTFE
*Cylinder material PVDF
*Seal assembly FKM/EPDM optional
*Structure material PVDF
*The drive pilot port can be installed in four directions

Performance characteristics
*Working pressure 0~5bar
*Temperature range: 5~100 ℃ (to be selected according to the temperature resistance characteristics of valve body material)
*The valve body has a cone-shaped flow passage and joint integrated structure, with minimal residue and displacement characteristics of different media

Application
*Photovoltaic
*LCD panel
*HDD Manufacturing
*Semiconductor
*Electroplating
*Integrated Circuit
