A useful option to use in conjunction with a Mucon Iris Valve is a LINER. A Liner is simply a tube of flexible material, which passes through the valve, which is constricted (or throttled) by a closing diaphragm.
Why use a Liner?
TYPES OF LINER
LINER "HEM" OPTIONS
As already mentioned liners can be fitted with flanges at both ends. i.e. Double Flanged liners. Free hanging liners can be furnished with a variety of "hems".
DIAPHRAGM / LINER COMBINATIONS
For the majority of applications a rubber liner (abrasion resistant or Food Quality) is used in conjunction with a fabric diaphragm. The fabric diaphragm giving the best "strangling" characteristics. - Fabric Diaphragms / Fabric liners are O.K. - Fabric Diaphragms/ Coated Fabric and Rubber liners are O.K. - Coated Fabric or Rubber Diaphragms/ Coated Fabric or Rubber liners can be problematic and should be avoided. Liners can be fitted to series AS,AD,BS,BD,C,ED,and H valves and are fabricated from the following sheet materials:
Variations of construction of some liners is available for applications that may involve liquids.
Please refer to Process Components for advice.
