The F89 series is an enhanced offering and succeeds the previous models. Direct mounting on butterfly valves eliminates the need for a bracket kit, which reduces valve package cost and overall dimensions for users. A more compact profile enables ease of valve automation and minimizes equipment footprint — a considerable advantage in applications where space is limited. All models include dual travel stops as standard, which allow for independent, easy and accurate adjustment of the close and open position.

Up to 12 pre-compressed captive springs provide improved maintenance safety and are designed to accurately match specific ball and butterfly valve torque requirements. In addition, F89 actuators provide an improved spring torque. This optimized torque range facilitates reduced size and increased flexibility. Powder coating of the springs also protects against corrosion, further reducing maintenance requirements. Plus, the use of Pentair’s high quality actuator for both ball and butterfly valves enables customers to lower their cost of ownership.

Optimized for the Pentair quarter turn valve range, the F89 forms part of a fully tested and installation-ready valve automated package. By providing the valve and actuator, and handling procurement and installation as the OEM, Pentair enables customers to reduce multiple vendor sourcing and third party automation costs. In addition, having undergone extensive testing as part of a validation program, the F89 series meets EN15714-3 standards and achieves SIL rating.
