Important: All V43/V243 water-regulating valves are designed for use only as operating
devices. Where valve failure can result in personal injury and loss of property, it is
the responsibility of the installer to add and maintain devices (pressure relief or
safety shutoff) or systems (alarm or supervisory) that protect against, or warn of,
device failure.
Note: The V43 and V243 Series Head Pressure Regulating Valves are available for cooling applications only (direct acting).
