The parts of a simple worm gear operatorWhile associations like AGMA have done much to provide standards for gear design and materials of construction, the slow operation, high torque and relatively low-duty cycles associated with manual gear actuators fall outside the normal service criteria upon which those standards

MANUAL ACTUATORS. INTRODUCTION. Butterfly and ball valves are typically supplied with either a traveling nut or worm gear type actuator. Both types are listed in the applicable AWWA Valve Standards, C504 and C507. Each type has some important characteristics that affect the performance of the valve assembly and
There are a variety of options to achieve this, including handwheels, levers, gears, and actuators. Manual operators Optimizing for number of turns and/or rim pull can provide a manual operator with a solution for applications where traditional worm gears would exceed rim pull or number of turn limits. The disadvantage of
Henry Pratt Company furnishes worm gear actuators upon request. We offer a variety of different manufacturers' designs tailored to each project specification requirement. Cylinder and Electric Motor Actuators. Pratt® valves can be equipped with a wide range of cylinder and electric motor actuators to meet your special.
M Series handwheel gear actuators (figure 1) are totally enclosed, weatherproof, worm gear actuators for reliable manual operation with Fisher A11, A31A and A41 High Performance Butterfly Valves. The M actuator consists of a body housing, cover, worm gear, input shaft, and handwheel. The housing is grease packed.
20 Aug 2012 THE COSTS. What are the costs associated with amplifying force through our manual actuator? The first cost is hard cash—the worm gear actuator will cost more than a lever or handwheel. Second, machines are not perfect, which is demonstrated in efficiency losses through heat and wear. As it turns out,
