MODERN W-450
Automatic pacing with cylinder, wall or cabinet mounted systems
MODERN's W-450 Automatic Gas Control Valves are systems that can be economically justified for even the smallest water or wastewater applications. Not only do you save floor space, but you also realize savings in initial equipment costs. The chemical resistant wall-mounted design incorporates all the control electronics necessary for automatic flow proportioning, eliminating the need for a separate and expensive controller.
The benefits do not stop there, however. In MODERN'S chlorinator system, the controller (vacuum regulator) and injector are molded of heavy-duty, chlorine resistant materials in order to reduce the number of parts, simplify maintenance and extend the units service life.
MODERN has designed the pacing valve so it can be operated by a wide variety of primary elements; open channel, propeller and other types of flowmeters.
Automatic flow proportioning takes the guess work out of regulating the gas feed rate every time the flow changes. MODERN's W-450 automatically regulates chlorine feed into a flow stream in direct proportion to the quantity of fluid being purified. A dosage control knob is provided to increase or decrease the gas feed rate. Once set the dosage will hold at a fixed value with a variation in flow from minimum to maximum. The dosage control knob also permits an increase up to twice the design dosage at half the maximum flow. It also features controls that allow you to manually operate the valve in the event of a power failure, loss of input signal or manual override.
