1-1/2″ Flow Check Control Valve

  • SKU: 1770

$101.60

Used to prevent “gravity” circulation in forced hot water heating systems during periods when the boiler is hot, but the space heating zone is not wanted. This makes it possible to use the heating boiler to maintain domestic hot water year-round. This valve can also use in systems with multiple circulator zones to allow heat to flow only into the zones that are calling for heat. In addition, the thumb screw can be opened manually for gravity feed applications, if the main circulator stops operating.
