Abstract
Surfacing is realized by fusing refractory alloy rings on the effective areas of valves. The apparatus comprises: a heater, a valve clamping device and a manipulator adapted to receive and to convey a valve with a ring on the stem thereof to the heater zone simultaneously positioning said valve head downwards. The manipulator is operatively connected to a platform on which a feed mechanism adapted to feed the valve to the heater and to the valve clamping device, a sprayer and an unloading chute are mounted. According to the motion of the manipulator the platform alternately positions under the heater the operating mechanisms mounted thereon.
