Case Studies

Case Study #1 - Cement

AKO Pinch Valves used in Cement Plant

Case Study #4 - Automotive

Automotive Foundry Changing to AKO Pinch Valves to Gain Longer Life

Regular aluminum-body AKO pinch valves are used throughout a well know automotive foundry on their core machines. With foundry sand the valves have continuous exposure to the most physically-aggressive environment possible to imagine. Supplied in standard form with a polyester powder-coated finish, the new AKO valves have so far lasts 12 times longer than the competitors’ valve that AKO replaced. Right away the AKO valves, in addition to giving longer life expectancy, represented huge cost savings to the customer... read more »

Case Study #5 - Glass Production

Maintenance-Free AKO Pinch Valves Help Quality Glass Production
