Low Leakage: Tight shutoff characteristics (ANSI Class IV) ensure energy conservation and prevent "creep" during off-cycles

This self-acting water regulating valve operates on the principle of pressure changes within the element

Note that while this is a high-performance HVAC control wire

ensuring stable modulation and mitigating hunting in hot or chilled water applications

Resideo PV125P Eliminator 30067439-890 Low Leakage: Tight shutoff characteristicsThe Resideo PV125P Eliminator is a heavy duty 1 1 4" SuperVent air eliminator designed for high performance air removal in residential and commercial closed loop hydronic heating and chilled water systems. Engineered with a robust bronze body, this unit effectively breaks down and purges microbubbles and entrained air from the system fluid, preventing the gurgling noises and air locks that lead to circulator damage and inefficient heat transfer.
