Why choose the Hemiwedge® Cartridge Valve for your Processing application?  Here’s a perfect example:  

Situation:  A customer needs an emergency shutdown valve (ESD) to isolate the feedstock to a processing unit. They want to replace traditional valve designs that have the potential to leak.  The existing valves are a common design (quarter-turn ball valves) and rely on pressure to achieve their seal. In an ESD application the customer doesn't want to worry if pressures will be sufficient to maintain the seal. They decide they need a more reliable, mechanical sealing valve to ensure a positive, bubble-tight seal in case of an emergency.

Solution:  The Hemiwedge® Cartridge Valve is selected because its mechanically seated design provides a reliable, wedging seal for maximum seating performance in any situation. It will provide zero-leakage at high or low pressures.
