Unirain SA products

Every model of Unirain sprinkler allows using three different kinds of vanes to achieve the desired coverage and pulverisation balance according to the available system pressure. The Unirain exclusive system provides high uniformity coefficients.

Designed to efficiently extract air trapped in pipes, filters, tanks and other places where unwanted air might cause performance problems. The release valves are located at the outlet of pipes whose slope varies according to the hydraulic gradient, in areas where pipes are located above ground level, in long pipes with uniform slope, at the input of measuring instruments, the output of reducing valves, in diameter reductions, pumps, filtration systems, and on both sides of a subterranean crossing road. For correct operation, the valve should always be in a vertical position. It is recommended to install a manual ball valve under the ARV, in order to make maintenance and repair operations easier without shutting the whole system.

Designed to efficiently extract air trapped in medium-sized pipes, large filters, tanks and other places where the absence of air is required for correct functioning. The release valves are located at the outlet of pipes whose slope varies according to the hydraulic gradient, in areas where pipes are located above ground level, in long pipes with uniform slope, at the input of measuring instruments, the output of reducing valves, in diameter reductions, pumps, filtration systems, on both sides of a subterranean crossing road.
