Top-mounted eccentric half-ball valves use eccentric valve body, eccentric ball and seat, the valve stem for rotary motion in the common trajectory of automatic centering, the tighter the closure process, to achieve good sealing purpose. The ball and seat of the valve are detached, eliminating the wear and tear of the sealing ring, and the non-metallic elastic material is embedded in the metal seat, so that the metal surface of the valve seat is protected. The products are suitable for steel industry, aluminum industry, fibers, tiny solid particles, pulp, coal ash, liquefied petroleum gas and other media.
Pressure loss is small, fully open when the water loss is small, smooth flow path, and the media will not be deposited in the valve body in the cavity; resistance to particle wear, V-shaped openings between the ball crown and the metal valve seat has a shear effect, in the process of closure, only in the back moment the ball crown to the valve seat, do not form friction, and the valve seat is made of nickel alloy, is not easy to be scrubbed and worn, and therefore suitable for containing fibers, tiny solids particles, slurry and so on;
Suitable for high-flow media, straight-through flow path, eccentric a crankshaft so that it is suitable for high-flow with no vibration; use long: no wearing parts, due to the role of eccentricity, the valve open and close the sealing surface of the friction between the use of long; easy to maintain, the valve does not need to be removed from the pipeline for maintenance, as long as you open the bonnet can be repaired; suitable for water, sewage, containing small solids, water, steam, coal gas, natural gas, oil and so on.
