For Pharmaceutical, Biotechnology,
High Purity Chemicals and Semiconductor Process Equipments
(Two-way Shut-off Valve)
Excellent performance with several types of chemicals
Lightweight, Compact construction.
The body is made up of high quality stainless steel (SUS304)
One touch connection operation. The design construction prevents fluid leakage on disconnection and allows minimum pressure losses.
Various packing materials Fluorine rubber, Ethylene propylene rubber, Prfluor, etc. are available to suit various application requirements in medicines, high purity chemicals, pure water, air, gas etc
