This 4 inch horizontal PVC valve is a float-operated valve with throttling capabilities that will cycle as required. Fluidtrol's modulating type float valves are intended for use i n aquatic systems where self-regulating flow is required. They work to make gradual adjustments to main drain flows based on surge tank water levels. This vertical float valve comes standard with two butyrate float balls and feature polypropylene valve construction with stainless brackets and hardware.The Horizontal Modulating Float Valves are designed to be used for either vertical or horizontal pipe lines and have a working range of no less than 30 inches. They are designed to modulate the flow of water from the main drain to the surge pit or tank. As the water level in surge tank rises, the valve closes, limiting the return water that is coming from the main drain. That allows more water to flow from the gutters. They can only be used on systems where the tank cannot flood on system shut down. Show more
