Features & Benefits :
- Lubi Triple Duty Valve is a device which directly mounts to the delivery side of horizontal or vertical centrifugal pumps.
- It is designed to reduce space and installation cost by combining all the functions normally required on the discharge side of most HVAC systems into one convenient design.
- It features a (i) calibrated balance valve, (ii) non-slam check valve, and (iii) positive shut-off valve all combined into one.
- Soft seated and accurately guided spring loaded disc ensures a leak free seal.
- Triple Duty Valves can be inline or 90° degree configuration.
- Spring-loaded disc ensures positive sealing and eliminates chatter.
- It also provides positive shut-off allowing you to isolate the pump from the rest of your system.
- The non-slam check valve prevents backflow and gravity circulation in staged pumping and parallel pumping systems, preventing damage to the pump and unwanted heat transfer through your system.
