Abstract
A valve and use of a valve. The valve changes the direction of flow of a fluid in pipings conducting the fluid to and from a heat exchanger. A cylindrical casing and a valve body enclosed therein can be rotated between two positions. The valve body has three flow passages. A fourth flow passage is constituted by the space between the house of the valve and respective walls around the flow passages in the valve body. The entire valve is flushed by the fluid during operation, thereby eliminating the risk for accumulation of dirt in the valve.
