Description
The Itron-Actaris 762646 Blue Adjustable Spring is a control part that is used to regulate the pressure settings when placed in the gas valves of the HVAC systems. It has a considerable role to play in offering variable resistance in the valve mechanism that enables the operating pressure to be set at 8 to 14″ of water column. B42 series valve housing spring adjustment is done by either fixing a spring or adjusting the spring to the required setpoint. In its use, it enables the control pressure to be applied correctly and also provides a uniform response of the system.
