Hayward Introduces New Line Of Large Polypropylene Ball Valves

The Hayward Manufacturing Company, Elizabeth, N.J., has begun the manufacture of 4-inch and 6-inch polypropylene ball valves.

The 4-inch valve features Hayward's "fullflow" design. This means the opening through the valve is a full 4 inches—the same as the pipe size.

The 6-inch valves feature a Venturi design which minimizes turbulence and pressure drop.

The 4-inch valve is available with either threaded or flanged ends. The 6-inch valve has a Van-Stone type flange which can be rotated around the valve end and makes it very easy to install.

These new valves are made of 100-percent virgin, unfilled polypropylene. They are ideal for corrosive systems or where high purity is required. These valves will find wide use in the chemical, food, marine, and other industries where an electrically neutral, chemically inert valve is required. These polypropylene ball valves can be used at temperatures up to 180 °F, and are rated at 150 psi.
