Cupola valves

Our Cupola Valves

The Kopar Cupola Valve is used as a feeding valve for pressure injectors. Cupola valves are ideal for solutions which require valves that withstand high wear and tear, high pressures or hot conditions. Very highly abrasive materials such as sand, cement or ash can be conveyed with high capacity without the fear of dust flying around, since the cupola valve is completely dustproof.

Designed to last

Designed to withstand 10 bar pressures, our cupola valves are designed to last. High wear and tear is no problem for this robust valve. Even hot conditions, or ATEX environments are no match for our cupola valves.

Kopar Cupola Valves are extremely durable, but in case of a failure or a regular need for servicing, the valve can be changed within an hour and your facility is up and running again. There is no need for large scale shutdowns with our solutions.

Our cupola valves have been in developement for decades now, continuously improving with the experience we receive from our customers’ needs and different behaviour of materials. Over 400 manufactured cupola valves are already around the world feeding material. Let us make your material flow better!

Technical Specifications

The valve solution consists of upper buffer bin (optional), cupola valve, pressure vessel and control unit. The material flows to the pressure vessel, and when it is filled, cupola valve closes and conveying sequence starts until the vessel is empty.

Used materials are carbon steel, wear resistant steel, acid proof stainless steel or stainless steel.

Suitable usage cases for Cupola Valves

Cupola valves are best suited for energy and power industries, pulp and paper plants, metallurgy, minerals and chemicals. The suitable solutions to pump through the valve include concentrates, metallurgic dusts, asphaltene, ash (boiler bottom and fly), lime and limestone, sand, sulphates, oxides, soy and pigments.

Cupola valves are at their best when they are used with our other solutions. Read more about our pressure injectors and pipeline components!
