Butterfly Valve SEALS- sized and matched by valve brand
HD Process provide seals for a range of butterfly valve brands. In order to assist confirming the best option for a replacement seal for your butterfly valves, included on this page are a table of key dimensions for 7 different series of butterfly valve seals which are available
These include a generic (unbranded) replacement for the Keystone F 250 seal, our own seals for our Bardiani, Tassalini and SMBV range butterfly valves, with options for other brands of seals available.
There is little compatibility between various brands of seals within a particular size with thickness of the seal in multiple dimensions along with various diameters in ridges making it difficult to swap one seal for another. However we have provided a chart here with the approximate for main dimensions for some of the seals we hold off-the-shelf.
There will be additional dimensions required (addtional to the 4 x dimensions here) in order to guarantee a seal will fit valve - (eg dimensions of any ridge or step etc). However these may be enough to start the identification process or confirm a seal is close to the correct size.
Note also that after a period of use elastomers can both expand and contract in various on the dimensions compared to an original seal (due to whether this is being abraded, mechanically compressed or expanded by liquids over time)
