This plastic ball valve is equipped with an MT41.S4.F07-F10.CH22 spring-return actuator and MS41-21ST0T technopolymer limit switch. To add some controllability to operating speed, a CF3 speed control plate w/ NPT ¼” adapter plate is mounted to the actuator’s Namur interface. The CF3 speed control plate allows a degree of control over the supply and exhaust air flow speeds, enabling the user to slow down the opening and/or closing actuation speed. This basic device can add extra control over the flow profile without breaking the bank.
