Pinch Valve Liner Service Life

The Pinch Valve liner (also known as sleeve, hose, tube, diaphragm, bladder, rubber membrane etc) is the only wetted part to a Pinch Valve, making it the only part that needs replacing. The liners do need replacing and servicing from time to time, but because they are the only part that need replacing, this makes the total cost of ownership of a Pinch Valve much less compared to other valve types.

For more information, please visit lined control valve.

It is not possible to guarantee the lifetime of a pinch valve liner, but reading some of AKO’s customer case studies may give an idea for certain applications. If the liner is looked after to the best of the users ability, under the correct recommended specifications, then the best possible lifetime of the pinch valve and it’s liner will be achieved.

Lined Control Valves Series 132000 (Flow Control Valve)

Corrosive fluids, including both gases and liquids, require special attention when it comes to the materials used to build the valve and Flowserve offers a wide range of choices for these applications. The company has experience in building valves from Carbon Steel, Stainless Steel, Titanium, Hastelloy, Alloy 6, Inconel, Monel, and many, many others. For fluids that require even greater chemical resistance, Flowserve offers a variety of solid plastic and plastic lined valves.

The new Series 132000 control valve completes the range of lined valves within the FLOWSERVE corporation. Many years of experience in the manufacture of lined ball and plug valves and the sophisticated experience of manufacturing excellent reproducible trims for linear valves are combined in this new product. High quality lining materials such as PFA (standard), PVDF, PP, ETFE and FEP as well as PFA antistatic cover most mediums and applications. The revolutionary PTFE bellows design allows a standard pressure rating of PN16. The increased flow capacity means that the most economical valve can be chosen for the application.

The liner material, the seat and the bellows seal are the only parts which are in contact with the medium. High quality lining materials such as PFA, (Perfluoroalkoxy resin) protect the metal parts of the valve assembly. T-grooves provide an extremely positive connection between the liner and the valve metal body, especially important in vacuum applications. Liner thickness is at least 5mm (3,5 mm liner thickness for DN 15 / 1 /2″ and DN 20 / 3 /4″). Liner materials are available in most common combinations. PFA, FEP, PP, PVDF ETFE or antistatic PFA cover most application requirements.

Standard PN 16 bellows seal manufactured from modified PTFE (TFM) for all applications. Extensive bellows life-cycle testing is based on extreme environmental conditions. All tests are performed at a temperature of 120 °C and 16 bar pressure. The optimized body design of the lined valve series 132000 allows Flowserve to offer one of the widest ranges of Kvs / Cv-values for each individual valve size. This means that smaller valve sizes can be offered with larger Kvs / Cv-values ensuring economical dimensioning. With more than 35 years experience in the manufacture of smallest Kvs / Cv-values Flowserve has gained a reputation as the ”Small Flow Specialist” with the ability to manufacture “reproducible” trims.
