This Salmson inline isolating ball valve (15mm male x male) was used on some older solar hot water circulation systems as a simple isolation valve only.
This product has now been discontinued and has limited stock by Solar Hot Water Parts due to lack of ongoing supplier availability and because modern solar systems now require improved pump protection.
Recommended Replacement (Current Standard)
For servicing or upgrading solar hot water systems, we recommend replacing this valve with a combined non-return isolation valve, which provides:
-
Isolation for servicing
-
Built-in non-return valve to protect the circulating pump
-
Improved long-term reliability
Recommended product:
