iPolymer Water Valve (WV) is manufactured in three material choices: PVC, Polypropylene, or PVDF. The valve has a spring return and is pneumatically actuated to open or close depending upon the model. The valve is compact and comes with four tapped holes on the base for ease of mounting. This valve replaces the older TEQCOM H2O Valve family. Contact iPolymer Customer Service for assistance.
