Though there are two valves in one body, there are no differences in dimensions between double and single valves, and there is only a slight reduction in flow when compared to a single four-way valve. The valves can be combined with Moduflex Dual three-way or single four-way valves of either Size 1 or 2 valves without transition kits. Dual 4-Way Valves are available in 24-Vdc solenoid or air-pilot operated versions with a universal manual override. The manual override is available as either locking or nonlocking, and can be changed in the field to nonlocking override only. This helps with machine set-up. And when the locking override is disabled, unwanted locking of the manual override is eliminated.
