What is it?
The Triple Duty Valve is a quiet operating heavy-duty valve which performs all of the functions normally required on the discharge side of hydronic pump systems.
It serves three fundamental purposes for maximizing the hydronic systems operating efficiency:

System balance valve
Non - slam check valve
Shut off valve

Triple Duty Valve
• Lowest pressure drop
• 3-Valves in one
• Maximum range of control
• Calibrated nameplate and memory button
• Backseating valve stem
• Minimizes cost and reduces installation time
• Meets ASHRAE 90.1 requirements

How does it work?
The system flow is able to be set accurately by adjusting the stem height to the proper reading on the calibrated nameplate. The spring-loaded disc prevents valve chatter, and assures positive shut-off.
Why use it?
There are three primary reasons why we use a triple duty valve:

To set the flow, and pressure, to the circuits that the pump is providing circulation to.
To prevent back-flow from occurring in the system.
To allow isolation and servicing on the pump.
