The set of O-ring and centre seal is precisely dimensioned for the Astral six-way valves numbered 20565 and 20569, which are used with sand filters with a side or top connection.
Wear of these seals manifests itself as water seepage at the rotary handle of the valve or incorrect switching between the operating positions of filtration, backwash, or water drainage.
Timely replacement of both seals at once extends the service life of the entire valve and prevents the need to purchase a new multi-position part.
Installation can be handled by a skilled customer with simple tools, or by a service technician during regular annual maintenance of the filtration.
