The KSH Type GVO counterflow valve enhances regenerant distribution during downflow regeneration by employing an internal sinker (weighted body) that temporarily narrows the valve opening during regeneration cycles. Once the filter returns to service (filtration mode), the valve reopens to normal flow. This design ensures more effective and uniform regenerant contact and improved system efficiency. Manufactured by KSH Germany and distributed exclusively in New Zealand by Absorb It Ltd, the GVO is ideal for systems requiring precision control over regenerant flow.

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.

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.
