Technical Information

Nylon and PVC Valves offer structural simplicity and superior hydraulic performance for surface or subsurface agricultural applications. The valves operate by pipeline or external pressure and the reinforced rubber diaphragm seals the water passage when the line pressure reaches the valve’s control chamber. They are simple to install with slip or threaded connections and available in 1” to 6” sizes.

Applications

Water control in PVC networks.
Use in surface or subsurface applications.
