- Cavity Relief
PosiWell® incorporates a cavity relief valve as a standard feature, recognizing the potential risks associated with pressure buildup within
pipelines. Cavity relief is able to relief either upstream or downstream as specified by the user - Local Indicator
PosiWell® showcases a distinctive orange visual indicator as a standard feature, which clearly indicates the valve’s fully closed or opened position - Enclosed Yoke
PosiWell® engineers the stem to be enclosed within the yoke, a design aimed at eliminating any potential risk of foreign debris causing
damage to the stem - Bleed Option
Flushing plays a crucial role in minimizing the risks associated with leakage and system failure. That’s why PosiWell® includes a sizeable
bottom drain valve specifically designed for cavity draining, offering the additional option of an end-flanged configuration - Leak Verification
PosiWell® has a stainless steel ball valve installed as a standard for users to verify for leakage
