Spherical cranes for VN mm water 25 from brass

Cranes spherical among elements of modern shutoff valves - the most popular. In spite of the fact that the crane from brass is structurally simple and original, the moment of its invention is definitely not recorded.

The patent for the device of the modern spherical crane was granted in 1971 in the USA. But then the invention could not win present popularity as at that time there were no materials which would have an opportunity to provide the small resistance of sliding of a locking sphere on sealing saddles at its full tightness, and also could maintain rather high temperatures. Tightness was provided only after creation of a ftoroplast - high-temperature polymer with low frictional properties.

Spherical cranes from brass received great popularity in the industry thanks to small dimensions at almost total absence of a channel of a working environment.

The product company "HUNDRED" introduced (Kharkiv) proizvodstvosharovy cranes from brass in Ukraine and offers distributors of shutoff valves, and also suppliers an opportunity to buy the high-quality certified cranes of various diameters of the Ukrainian production at low prices.
