• See Powermite 599 Series MT Series 2-Inch Pneumatic Valve Actuator Technical Instructions
(155-189P25) for details on the valve actuator.
* The standard three-way valves contain a 8 to 13 psi (55 to 90 kPa) spring range.
- For an alternate spring range of 10 to 15 psi (69 to 103 kPa), add an “A” to the end of the part number.
- For an alternate spring range of 3 to 8 psi (21 to 55 kPa), add a “B” to the end of the part number.
