The Pinch Valve is installed at ground level adjoined to a diaphragm pump. The valve operates a number of 50 cycles per day and is held in the normally open position. An air pressure amount of 4.5 Bar is used to seal the internal rubber sleeve tightly closed. When the rubber sleeve is open it allows a full and true clear bore with no dead spots or other restrictions. The free flow of product allows for an efficient and reliable production.
Reliable Pinch Valve Performance
The company have been using Pinch Valves from AKO UK for 3 years to date. The valve was already supplied in a new installation for water pH control that the company purchased. They have had no reason to change the Pinch Valve to an alternative valve type or like-for-like model by an alternative supplier because the site chemist confirmed that AKO’s Pinch Valve performs excellently.
The EPDM rubber sleeve inside the Pinch Valve, which is the only wearable part, is replaced every 18 months. The company have no further potential for more valves in the future and are just repairing the rubber sleeves when needed. AKO advises to keep one replacement spare sleeve on the shelf in case of emergency failures.
