Shutoff valves for a water supply system

Scope: Spherical cranes for HLV water, the Optima model, are used in systems of hot and cold water supply, including systems with drinking water, heating, transportation of compressed air and hydrocarbons. Spherical HLV cranes, the Optima model, are developed by engineers from Italy, especially for operation in Russia and have the raised resource. Distinctive feature of HLV cranes, the additional system is HOT & COLDapplied on cranes with the handle lever. The HOT & COLD system, this existence on the handle of the crane of additional rings of blue and red color that does more convenient use of HLV cranes. Design features: - The case of the crane is made of high-strength brass, method of hot stamping. - The rod is inserted from within the crane that excludes knocking-out of a rod pressure. - The handle is fixed samokontryashcheysya by a nut that excludes any untwisting. - The crane is maintainable, at the expense of a replaceable teflon epiploon and a clamping nut. - The barrier sphere will be subjected to diamond polishing, with the subsequent chromium plating. - In the crane heat-resistant teflon, with a working temperature up to 230 Pages is used. Technical characteristics: - Passability - full bore; - An interval of temperatures - from-30 to +120 With;
- Pressure - from PN40 to PN16 (depending on diameter)
- Range of diameters - 1/2 to 2 inches
- Service life of 30 years
- Resource of 55 000 cycles
