Ball Valves (operated automatically or manually) are used mainly with viscous fluids containing solid particles and in applications requiring an unobstructed flow.
Check Valves, or non-return valves, prevent the fluid from flowing backwards and ensure that it flows in only one direction. They are used in food-processing, cosmetics, pharmaceutical and chemical industries as well as in the beverage, wine and oil production. ATEX versions are available.
Overflow Valves are designed to protect installations in the pharmaceutical industry and are used for pressure bypass to protect production lines, pumps, fittings, tanks, etc. They are used to prevent pump cavitation by creating counter pressure.
Pressure-vacuum valves maintain atmospheric pressure inside a tank while being filled or emptied. They are widely used in the food-processing, wine-making, cosmetics and chemical industries as well as in the beverage and oil production.
