The replacement of galvanic chrome plating of ball valves with high-speed flame spraying of nickel and cobalt-based alloys is the result of the development of the 1990s, which became the de facto standard in the production of modern valves and fittings in Europe and the USA.
Ball valves with consolidations metal on metal are applied in the most responsible processes. Therefore, the coatings of balls and saddles must meet the most stringent requirements for resistance to corrosion and wear, prevention of seizure of sealing surfaces.
JSC "Plakart" performs coating, supply of equipment, materials and spraying technologies.
Robotic systems of spraying balls allow to apply the coating with a minimum deviation in thickness, which significantly reduces the cost of subsequent machining.
