PN25/ 350PSI
TALOAR ductile iron wafer-type auto-flow balance valves can automatically maintain the flow of water systems constant within normal working pressure differential range, which does not require field or site commissioning. The shell is coated with epoxy resin. Measuring ports on both ends enjoy good self-sealing performance. High-precision valve core ensures correct and persistence of constant flow.
Auto constant flow, field or site commissioning is not required.
Reduced energy consumption and improved system stability.
Elaborate flow hole design, flow error within ±5%.
Stainless steel cartridge and spring, with longer service life.
Detachable bolt, making it easy to replace the cartridge.
Small and light, space saving.
Plug-in measuring point, allowing quick connection.

Note: In valve installation, it is strongly suggested that sufficient space should be left for easy maintenance in the future. A strainer shall be mounted in front of the valve to prevent foreign matter from blocking the valve.
