Electric Ball Valve (HS4810)

We are acclaimed to be one of the leading manufacturers, exporters and suppliers of Electric Ball Valve (HS4810) from China, India. Manufactured with a quality standard of ISO9001, this HS4810 Electric eccentric plug rotary ball control (shut-off) valve is used widely in the automation control in all types of industries. This Ball Valve works with 3-dimension software UG, simulated and analysed with NASTRAN and processed with advanced high precision digital control machine. Comprising of a micro-processor control, non-additional servo amplifier and a multiple limit of actuator, this Ball Valve is highly reliable for the control of viscous media.

Product introduction : HS4810 Electric eccentric plug rotary ball control (shut-off) valve is independently developed by our company for practical working conditions in the industry. It is designed with 3-dimension software UG, simulated and analyzed with NASTRAN, and processed with advanced high precision digital control machine. The product has good quality and is widely applied to the automatic control of petroleum, chemical, paper making, metallurgy, coal mining and water treatment industries.

Product characteristics :

• Micro Processor Control, mechanics and electrical integration, non-additional servo amplifier are applied to the electric actuator.
• The travel of valve can be setup freely, after which the zero point and measure range can be self-adjusted by the MCU of actuator.
• The sensibility of actuator can be self-adaptive to the actual working conditions and effectively avoid the vibration of valve.
• Multiple limit of actuator (mechanical, electro-pneumatic and over-torque) restricts the position of valve and protects the actuator.
• Electro-open or electro-close can be freely setup, with site manual operation keys to carry out electric operation for valve at site.
• Self-diagnostic functionï when the input signal is cut off or the valve is blocked completely, the actuator will alarm automatically and according to stated safe position, i.e., stay in same place or revert automatically.
• Options itemï local LCD, flow characteristics curve transferring, Field Busï water/explosion- proof design
• Eccentric structure can reduce the wear of seat and expand the lifespan.
• Guide vane in the end of core makes for the stable flow of fluids.
• Soft sealing type can reach zero leakage, hard sealing type plug and seat can be coated with high rigidity alloy to improve the wear resistance and corrosion resistance.
• Applicable to the control of media with high viscosity, fibre and granule.

Application standard :

• Quality system - ISO9001
• Design - refer to GB12338 MSS-SP-68
• Face to face - refer to GB12221-89
• Flange standard - JB/T79.1-94 or ANSIB16.5
• Test standard - JB/T7387-94

Details : Electric actuator drives upper shaft to rotary and realizes the open and close of core (offset ball crown). While open, the core rapidly breaks away from the seat which effectively reduces the wear of seat. While fully close, the slot between seat and body can ensure that the seat adjusts position under the extrusion of core, and thus ensures the effective contact of seat and core and realize the shut-off of fluid. Adjusting is realized by changing the flow area between core and seat.

Installation direction of valve :

• Adjusting type-the flow direction of fluid should be identical with the open direction of valve.
• Shut-off type-the flow direction of fluid should be identical with the close direction of valve.

Note :

• There are two standards for flange dimensions, JB/T79.1-94 and ANSIB16.5, and the dimensions above are according to JB/T79.1-94.
• If fluid temp. is higher than 200, bracket should be installed and dimension H should be added with the corresponding height of bracket.
• If differential pressure of fluid is different, the dimensions of actuator equipped will be different.
• While the valve is not standard configuration, the dimension will have some change, and please subject to the actual dimension.
