The main characteristics of the electric eccentric hemispherical valve: the valve seat and the ball will not cause problems such as jamming or separation, good sealing, and long service life. The electric eccentric semi-ball valve has a shearing effect between the ball core and the metal valve seat of the V-shaped incision, which is more suitable for media containing fibers, small solid particles and slurry. It is more suitable to control pulp in the paper industry. A practical operating product of the ball valve, the actuator is equipped with a 90° rotary electric actuator, which is more convenient for users to operate, light and remote automatic operation, which develops the scope of use of the hemispherical valve, especially in the harsh environment, which is not convenient for manual operation Or when it is normally open, the double eccentric hemispherical valve is equipped with electric actuator under the condition of supporting automatic computer operation.
The ball valve switch is light, small in size, can be made into a large diameter, good sealing, simple structure, convenient maintenance, the sealing surface and the spherical surface are often closed, and it is not easy to be eroded by the medium. It is used in many industries.
The valve has the advantages of a double eccentric hemispherical valve such as small opening force, can break the scale barrier when closed, and achieve good sealing performance, and it is not easy to wear. Corrosion-resistant material, so it is widely used in water, steam, sewage, papermaking, petrochemical, natural gas, solution and ore slurry two-phase mixed flow media, as well as dust-containing gas, particle-containing fluid, powder solid medium transportation ideal equipment, using electric operation, It is more convenient and suitable for management automation, remote control, equipped with electric signal device, which can be used for automatic operation and centralized control.
The electric eccentric hemispherical valve is suitable for sewage treatment, pulp, alumina, and urban heating and heating applications where strict standards are required; it is suitable for control of power plants, hydraulic slag removal or gas transportation pipelines.
The eccentric structure of the sealing surface enables the spherical surface to automatically compensate for wear and maintain the sealing of the valve with a long service life. The ball valve switch is light, small in size, can be made into a large diameter, reliable in sealing, simple in structure, easy to maintain, the sealing surface and the spherical surface are often closed, and it is not easy to be eroded by the medium. This product is equipped with a single and double cylinder series switch two-action partial-turn valve pneumatic device. Controlled by solenoid valve, remote automatic operation can be realized. Take advantage of the eccentric hemispherical valve (users of pneumatic devices can also choose their own models).
There are two types of valve surface paint: normal temperature and high temperature. Use 600℃ temperature-resistant paint for high temperature. After spraying, the paint will not burn, carbonize, coking, or change color after high temperature use. The ball valve is mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. Two-piece ball valves and three-piece ball valves are a new type of valve that has been widely used in recent years. Pneumatic half-ball valves have also been increasingly used in many industries.
Electric eccentric hemispherical valve V-type ball valve is suitable for 150～600LB, PN1.6～6.4MPa, working temperature ≤300℃ on various pipelines (high temperature customization), used to adjust the pressure and flow of the medium in the pipeline, using different materials , Can be respectively applied to water, steam, oil, nitric acid, oxidizing medium, urea, ammonia brine, neutralized water and other media.
