Compact air operated 2 way valve features PTFE diaphragm with no wetted elastomers or metals. The PTFE diaphragm is backed with an elastomeric NBR diaphragm to enhance flexibility and improve longevity. Valve body wetted parts are all virgin PTFE, port sizes 3/8 or ½” BSP or NPT thread encased within a compact strong stainless steel cage mounted with small pneumatic aluminium alloy JIG cylinder. This valve is ideal for high purity processes such as deionized water, as well as ultra-harsh chemicals not compatible with elastomers. Ideally suited for use with strong acid and alkali media, such as chemical dosing, cleaning and processing systems. Function 2/2 way either normally closed (failsafe closed) or normally open (failsafe open)working pressure range from vacuum to +5 barg, orifice 8mm, air pilot pressure required 1.5 to 9 bar.
