The Series 74/75 can be fully automated throughout its size range, by either pneumatic or electric actuators. Flow Line’s extensive automation capabilities are due to the fact that we developed our actuator and accessories from the ground up. Our automation products were designed with the torque needed to be able to automate all Flow Line valves. Because all Flow Line valves are kept up to the latest ISO 5211 standards, there is no need for brackets and couplers when using Flow Line actuators on Flow Line valves. We give you a single source for quality automation packages.
