Product features

The electric internal thread ball valve (also known as the electric screw ball valve) refers to the threaded ball valve on the nut and pipe joint, which is formed by connecting the electric actuator and the internal thread ball valve in a direct connection way. The electric internal thread ball valve is generally small, and the diameter below DN50 is common. Because it is difficult to thread the pipe connected to the valve, it is generally not suitable for use beyond this size. The electric internal thread ball valve is made of different materials, which can be applied to various media. It can be cut off or adjusted in two positions on various pipelines with a pressure of PN1.0~4.0MPa and a working temperature of - 29~300 ℃. The utility model has the advantages of simple connection, compact structure, small size, light weight, small resistance, stable and reliable action, etc.

Standard specification for electric internal thread ball valve:
 
Inspection standard: JB/T9092, API598, EN12266
Product standard: GB/T12237, ASME16.34, API608
Pipe thread standards: GB/T7306, GB/T7307, ISO7-1, ISO288-1
ASMEB1.20.1, BS21, DIN2999/599, BSP

Test pressure: 1.6 2.5 4.0
Strength test: 2.4 3.8 6.0
Sealing test: 1.8 2.8 4.4
 
Principle of electric internal thread ball valve:
 
The actuator of the electric threaded ball valve is equipped with a built-in servo system, which can be operated by inputting 4-20mA signal and 220VAC power supply without additional servo amplifier. The ball rotates 90 ° perpendicular to the channel axis to achieve proportional adjustment or cut-off control of the fluid medium in the pipeline. The electric threaded ball valve is a straight through valve. The medium in the fully open state has no contact with the sealing surface, and its service life is long Low friction and wear rate between sealing surface and medium, suitable for medium containing particles and corrosive fluid.
