Investment Castings For Pinch Valve

Heavy-duty components for supporting demanding applications

Pinch valves are the silent workhorses of multiple heavy-duty industries where the flow media rotates between sludge and streams of highly abrasive particles. It leverages a simple full-bore elastomeric sleeve design to toggle abrasive media flow, with the sleeve also acting as an impact absorber. Engineers and procurement managers alike prefer this flexible barrier valve because they are easy to operate and even easier to maintain.

At Super Quali Cast, we manufacture investment castings for pinch valves, including pinch valve body castings and bonnets for demanding industrial applications. Our pinch valve bonnets and bodies support a range of internal mechanisms, flanges, and actuators. We complement standard designs with proprietary builds that are an exact match where product-application fit is concerned. Rapid prototyping, fast tooling, thorough testing, just-in-time delivery, and scalable supply are some of the reasons why local and global OEMs and valve manufacturers work with us.

Applications of Investment Castings for Pinch Valves

Pinch valve castings are used in piping systems across industries that handle abrasive, corrosive, slurry-based, and other challenging media.

Mining: Pinch valves are used to effectively toggle the flow of slurry, tailings, and crushed ores from the point of extraction to refineries.
Utility: The valves enable unhindered flow of sludge, grit, and other suspended media in wastewater while also isolating them for treatment.
Chemicals: Used in systems that handle viscous liquids, which otherwise would clog regular valves.

Frequently Asked Questions

How many types of pinch valves are there?

There are two types of pinch valves, based on their internal mechanism. There are pinch valves where a compressor squeezes the sleeve against a raised fixed seat on the valve’s inner body. The other type uses a mechanism that raises the seat to meet the descending sleeve lining, thereby creating a pronounced pinching effect.

Do you create valve components for both these types of pinch valves?

Yes, at Super Quali Cast, we produce valve bodies and bonnets that support both valve mechanisms. Our lost-wax casting expertise coupled with our top-of-the-line CNC support means we deliver products with tight tolerances and excellent geometric accuracy.

Do you provide the inner sleeve used in pinch valves?

No, we do not provide the elastomeric inner sleeves that are used in pinch valves. We only provide those components that can be manufactured using the investment casting process.

Which is the best material for casting pinch valve components?

The best material for casting pinch valve components is the one that meets your project’s goals. The valve body and the inner elastic sleeve need to be solvent-compatible as well as support the right temperature and pressure. Common materials used to create valve components include low-carbon steel for carbon steel pinch valve castings and 304/316 grades for stainless steel pinch valve castings.
