From Hayward Flow Control

Since the introduction of PVC in the U.S. during the 1940's, thermoplastic valves, pipe and fittings have gained wide acceptance. They are often the material of choice for systems that were traditionally designed in metal. Unlike metal, however, plastic valves and components have a high resistance to corrosion, will not scale or rust, and will not contaminate sensitive fluids. Further, as non-conductors, they are immune to electrolytic and galvanic corrosion. Equally important, they contain nothing to leach out and contaminate sensitive fluids.

Electric Valve Actuators
Electric valve actuators mount on valves which, in response to a signal, automatically move to a desired position using an outside power source. Single-phase or three-phase AC or DC motors drive a combination of gears to generate the desired torque level.
