Electric ball valve-The Yangzhou Bernard valve automatic control Equip

The electric ball (sphere) around the vertical channel axis 90 º valve by the electronic transition back to the rotary electric actuator and the structure of O-type valve is a rotary type high-performance adjustment or switching valves, and to accept(DCS, PLC system) instrument the source of the current signal or voltage signal input and output of industrial automation and control, can adjust the proportion of the fluid medium in the process piping or two switch control to achieve the flow of the fluid medium, pressure, temperatureautomatic control of liquid level and other parameters.
Features
A. Electric ball valve fluid resistance is small, and all valves in the fluid path of least resistance kind of power, AC220V, AC380V or DC24V power supply voltage to accept (4-20mA, 0-10mA or 1-5VDC) current signal or voltage signal, can control the operation, the output torque of the rotary, rotating sphere 0-90 º, will be able to complete the opening and closing movement or adjust the action.
Two. Ball core channel is smooth, easy deposition medium, can be pipelined through ball. Simple structure, light weight, good sealing performance. Especially suitable for situations requiring zero leakage rate.
3. HL type 3810R type, PSQ type rotary electric actuator for fully electronic drive unit of the O type ball valve, mechanical and electrical integration of structural design, position feedback of the machine servo operation and opening signal, position indicator, manual operation functions, functional, reliable performance, simple connection, as the power supply voltage AC220V or AC380V directly accept the signal of a unified standard (4-20mA DC,0-10mA DC or 1-5V DC, 0-10V DC)
This into the input signal corresponding to the displacement, angular displacement (0-90 º) movement to change the rotation of the ball core opening, so the input signal corresponds to a certain location opening to achieve proportional control action. (Two switch-to AC220V or AC380V supply voltage for power, motor reversing switch action, and at the same time the output of the switch valve position indication signal). Is a high precision, high-performance, high reliability products.

(A). O-floating ball-type structure; soft seat: the double inclined plane flexible (Teflon or polystyrene) right hand seat ring.
Hard seat: the seat of the cylindrical spring-loaded metal (alloy steel) hard ring.
Effectively reduces the coefficient of friction between the ball and the ring, and reduce operating torque. When the medium pressure is small, the ring contact with the ball is smaller, so a larger seal than the pressure to ensure reliable sealing ring with the ball contact area, when the media pressure, a corresponding increase, so the seat sealing the ring can withstand the larger thrust of the media without damage to ensure a reliable seal.

(B). O type fixed ball structure; soft seat: dual bevel spring-loaded (PTFE or right hand polystyrene) elastic seat ring.
Hard seat: the cylindrical spring or wave spring preload to compensate for moving the metal (alloy steel) Hard sealed seat.
Seal preload design is reasonable, reliable sealing performance, according to the size of the pressure, dielectric properties and sealing requirements different selectable imports of seal structure, export seal structure or import and export of the double seal structure. Sphere up and down from the valve on the two bearings to support the sphere of the fixed position, the sealing seat role is driven by a spring and media pressure to achieve, so the seat will not put too much pressure, the valve seat seal is not easy to deformation, the operating torque light, long life.
