Valves for Concrete Sugar based Admixture

AKO UK supply plastic pinch valves to a company who produce and supply ready-mixed concrete.

The ready-mixed concrete company have been using AKO Pinch Valves since 2008. The Pinch Valves were installed as original equipment but were of an Italian origin and they had difficulty receiving parts or spares as they no longer had an agent in the UK. This is why they changed to using AKO Pinch Valves for concrete.

Pinch Valve used within this application – VMP025.03X.72

VMP model, air operated, POM body, POM BSP internal thread end connections, natural rubber sleeve.

The update of product on their system has proved more than successful, due to the rubber inserts inside the valves not needing to be replaced as often as the Italian manufactured pinch valves for concrete.

Valves for Concrete Application Details
  • Product passing through the valves: An admixture (chemical liquid), mostly lignosulphate (sugar based).
  • Temperature: Ambient
  • Pressure: 100psi is available to close the Pinch Valves. However this is regulated to the operational pressure that they require.
  • Amount of Cycles per day: 50-80

The Pinch Valves are kept normally closed, with no degree of vacuum. There are no additional accessories involved with the valves.

The admixture is added to a bulk batch of the concrete mixture in order to turn it into cement as the final product.

The VMP Plastic Pinch Valve

The VMP Pinch Valve is a versatile and compact unit, not only suitable for concrete and cement applications but also many other types of industries. The choice of rubber sleeve materials is varied, which makes this valve option a preferred choice.

There is a positive total cost of ownership with this type of valve. The valve is made up of only 3 parts and the only wearable part is the rubber sleeve, which should be the only part to ever need replacing. Unlike conventional style valves where additional rings, seals, packing etc is required.
