[basic information]
         Electric V type ball valve, the ball core is V shape, can achieve linear adjustment, adjustable range. When the valve is closed, the wedge between the V notch and the valve seat acts as a wedge shear. It has self-cleaning function and prevents the ball core from being jammed. It is especially suitable for the freezing and scaling of pipelines. Suitable for controlling pulp and sewage containing fibers and particles, solids, suspensions, and particulate media.

[Valve features]
1, without any pipe joint of the integral body, so it is not affected by the pipe or bolt stress, and because the valve body without any pipe joint, so the pressure shell will not be pressure "mutation" influence;
2, with a V type valve body, even in small flow or high viscosity medium, but also in the entire range to ensure the accuracy of the control;
3, leakage proof and durable seat in its outer lining with stainless steel inner core PTFE cup or O type sealing ring, the valve seat made of tungsten cobalt hard alloy with large cross section, through a corrugated spring alloy reinforced seat structure;
4, when the valve is closed, producing wedge shear force between V notch and the valve seat, and has self-cleaning function and can prevent the ball stuck, especially suitable for freezing pipeline or containing fibers and particles of solid.


[Adaptive condition]
       The valve is an important executive mechanism of industrial automation control system, remote centralized control can meet the needs of computer program; now widely used in petroleum, chemical industry, gas equipment, nuclear power equipment, water treatment, air conditioning, iron and steel metallurgy, industrial furnace, tank equipment, brewing equipment, drying equipment, vacuum equipment, surface treatment, bio pharmaceutical, food machinery, textile, papermaking and other industries, the preferred product is construction of national defense construction, science and technology.
