Explosion-proof environment / Suitable for high-purity chemical liquids PFA lined diaphragm valve
A highly durable lining valve designed to withstand aggressive environments such as vacuum, high/low temperatures, and high-frequency lines.
We are proposing the "PFA Lining Diaphragm," which can be supplied in a short delivery time, to customers using PFA lining piping! In recent times, the procurement of fluoropolymer materials has been significantly disrupted worldwide, and we often hear about difficulties in sourcing PFA lining diaphragms. Amid this situation, inquiries about PFA lining diaphragms from GEMU, a global supplier of diaphragm valves, have been increasing. **Features of GEMU PFA Lining Diaphragm:** - All wetted parts are made of PFA and PTFE, suitable for high-purity chemicals and corrosive fluids. - The diaphragm is designed for high durability, capable of withstanding long-term use. - Spark tests are conducted on all lots, providing measures against electrostatic breakdown. - Various actuators, including electric, manual, and automatic, can be installed. - Material selection is available according to application, including SUS and resin. - Options with various feedback switches and controllers for flow control are also available. - The thickness of the PFA lining is around 3mm, designed to be strong against permeation.
