Hydroseal Canada's all-plastic titan Butterfly Valves are rated at a full 150PSI. Hydroseal Canada valves are constructed from a one piece body that incorporates fully supported flanged bolt holes to prevent stressing of the mating pipe flanges. Their heavy duty, industrial, robust construction stands up to the most demanding applications. The integral mounting pad ensures that any valve operator is used, lever type, worm gear or fully installed actuator.
