Actuators

Henry Pratt Company offers a wide variety of actuator styles to suit a multitude of applications. The Pratt valve is available with manual, buried service, submersible service, hydraulic or pneumatic, and electric actuators. Every actuator is specifically designed for long life in utility service with minimum maintenance. When manual actuation is required, the Pratt model MDT traveling nut type actuator is the ideal option for the Pratt valve. Pratt MDT manual actuators are available with a 2" nut for buried, submersible or vault service. For above ground applications, the MDT is available with a handwheel or chain wheel. Hand levers are available for valve sizes up to 10 inches.
