1 WATER NYLON AIR VALVE NPT D040
SKU: 7676205
The D-040 series Combination Air Valve has the features of both an air release valve and an air & vacuum valve.The air release component is designed to automatically release small pockets of air to the atmosphere as they accumulate along a pipeline or piping system when it is full and operating under pressure.The air & vacuum component is designed to automatically discharge or admit large volumes of air during the filling or draining of a pipeline or piping system. This valve will open to relieve negative pressures whenever water column separation occurs.
Maximum intermittent temperature: 194° F. | Due to its light weight, the valve may be installed on plastic piping systems, as well as other lightweight piping systems. | Reliable operation reduces water hammer incidents. | Lightweight, small dimensions, simple and reliable structure. | Dynamic design allows for high capacity air discharge while preventing premature closure. | The large size of the automatic air release orifice relative to the air valve body: Discharges air at high flow rates; Lessens the danger of its obstruction by debris; Enables the usage of the rolling seal mechanism, making it less sensitive to pressure differential than a direct float seal. | The body is made of high-strength composite materials and all operating parts are made of specially selected, corrosion- resistant materials. | Working pressure range: 3 - 250 psi. | Testing pressure: 360 psi. | Maximum working temperature: 140° F. | The discharge outlet enables the connection of a vent/drain pipe.
