FWS series
LUS series
The wafer FWS and lug LUS butterfly valves are ideal for applications in medium corrosion environments in the chemical, pharmaceutical, and textile industries and, more in general, for applications where elastomers cannot be used.
The two-part body, which is made of GGG40.3 nodular cast iron coated with epoxy powder, facilitates servicing.
The 316 stainless steel machined ball butterfly part is guided by lines to do away with fastening devices.
The dovetail gasket made of silicon coated with PTFE comes with grooving to seal the body optimally.
The FWS and LUS valves can feature a manually operated lever or a double or simple-acting actuator.
The face-to-face dimensions comply with the following standards:
• ISO 5752, series 20
• EN 558, series 20
• API 609, tab. 1
