Type GVU
The KSH Type GVU counterflow valve is engineered to enhance the distribution of regenerant during upflow regeneration cycles by using an internal float that temporarily reduces the valve opening during regeneration. Once the filtration (service) phase begins, the valve reopens to normal flow. This smart mechanism ensures more uniform distribution, higher efficiency in regeneration, and improved lifespan of your filter media. Manufactured by KSH Germany and supplied exclusively in New Zealand by Absorb It Ltd, the GVU valve delivers precise control and dependable performance in advanced filtration systems.
