GrowIrrigation supplies high quality but economical molded-in-place PVC ball valves and top-of-the-line CEPEX true union valves for your fluid handling needs as well as Air/Vacuum relief valves to avoid damage that can be caused by trapped air or vacuum conditions. Trust your agricultural air and fluid-handling application to Grow Irrigation.
Molded-in-place ball valves, also known as "Compact Ball Valves" are injection molded in a single step that results in economical and leak-free performance. The most common use for molded in place valves is applications where the valve opening is set once and is not changed frequently.
True Union ball valves have a built-in double union which allows for easy installation. Just as importantly, a sophisticated design results in smooth and easy handle turning, even on valves up to 4" diameter. Because of the easy and reliable turning action, the best use for true union ball valves is applications where openings need to be adjusted frequently.
Air/Vacuum relief valves should be installed at all high points of your system, with a minimum of one for each zone. Trapped air can damage pipes and cause "airlock" conditions to form which prevent plants from getting the water they need. Vacuum conditions that can occur during system shutdown can also damage pipes, and more commonly can cause clogging by sucking soil back into small drip emitter passageways. Air/vacuum relief valves solve these problems.
All GrowIrrigation ball valves are constructed with PVC bodies, ABS handles and EPDM seals. GrowIrrigation air vents are constructed from high quality polypropylene. All materials are resistant to most chemicals used in agricultural applications.
