Suitable configurations	Double-block valve assemblies and series connections

Choosing and fitting

Seal kits of this type are selected by exact valve series and manufacturer part number. They are not interchangeable between series; the kit must match the valve body, not just the nominal size, because internal seal forms and port arrangements differ. Before ordering, confirm the valve series and model markings on the valve body. Install using the complete kit, as individual gaskets may not have correct material pairing.

Signs of failure

Seals and gaskets deteriorate over time due to thermal cycling and exposure to gas or combustion air. This can lead to gas leaks, compromising burner performance and safety. A leaking valve may show signs of gas smell, pressure drops, or unstable flame. Regular inspection and replacement of all seals are necessary to maintain tightness.
