Type GVO

Type GVO
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.
