Electric three piece ball (ball) is an axis perpendicular to the channel axis to rotate 90 degrees of the valve, which is composed of rotary electronic type electric actuator and O type valve structure, regulation is a rotating type performance or switching valves, receiving industrial automation control (DCS, PLC) input and output to the source of the current meter the signal or the voltage signal can be adjusted or two switch control of the fluid medium in the pipeline proportion, so as to achieve the automatic control parameters on the fluid flow, pressure, temperature, liquid level etc..
Note: parameters are for reference only, or are not full. Valve can be used in accordance with the requirements of different pressure, material, caliber. Specific please contact or online advisory contact.
Port: Rp UNI/ISO7/1 of internal thread; socket welding and butt welding.
Operating temperature: -20 to +160
Working pressure: see figure.
Fluid range: air, water, gas, petroleum and petrochemical products, corrosive media.
The valve head size ISO5211 electric three piece ball valve (threaded ball valve) and butt welding ball valve is suitable for PN1.0~4.0MPa, the working temperature of -29~180 DEG C (seal for PTFE) or -29~300 (c ring as Polyparaphenylene) of various pipelines, used to cut off or connect the line of medium. Selection of different materials, can be applied to water, steam, oil, nitric acid, acetic acid and other media.
1 three piece electric ball valve fluid resistance, fluid resistance all valves in a minimal, with AC220V, AC380V or DC24V as the power supply voltage (4-20mA, 0-10mA, accept or 1-5VDC) current or voltage signal, the control operation can be, to rotary output torque of the ball rotated 0~90 degrees, will be able to complete the Rev. Close or adjust the action.
2 full electronic type electric actuator, adopts the mechanical and electrical integration structure, with built-in servo operation and opening position signal feedback, position indicator, manual operation function, strong function, reliable performance, simple connection, through the input current or voltage signal, changing the angle of rotation of the ball core (0-90 DEG arbitrary angle). To achieve proportional control action.
3 ball core channel is smooth, easy to deposit the medium can be pipelined through the ball. The structure is simple, the weight is light, the sealing performance is good. Particularly suitable for applications requiring zero leakage rates.
