Precision Engineering for Optimal Performance

In Comparison

Troublesome valve installations can cause “off spec” products, require constant maintenance, and restrict production time. Other valve styles, some of them originally designed for liquid handling, have shortcomings, as shown below.

Ball Valve

Ball valves were developed over a century ago for liquids and gasses. They are heavy and take up a lot of headroom. More importantly they have a dead space between the casting and ball that can fill and pack with product causing abrasive wear on the seals and ball or causing cross contamination/spoilage between batches.

Butterfly Valve

Butterfly valves have a vane in the center of the flow stream that can cause bridging and obstruct product flow. Since the seat and the vane are exposed they can wear quickly, making them unable to seal.

Slide Gate Valve

Slide gate valves can pinch and/or cut product, jamming the valve so it won’t close completely. The linear motion of the valve can drag material across the seal, causing wear and allowing product to leak out thru the sliding seal.
