Valve Actuator Is More Adaptable

- Aug 02, 2017 -


Valve driver is commonly used in the driving mode of the valve, usually referred to as the driving device in the form of the valve electric device, valve driver characteristics are as follows: 1 fast opening and closing, you can greatly shorten the time required to open and close the valve; 2 can greatly reduce the labor intensity of operators, especially for high-pressure, large-caliber valves; 3 Valve Control Actuators is suitable for installation in the position that can not be operated manually or difficult to close, easy to realize long-distance operation, and the installation height is unrestricted; 4. Automation for the entire system 5) The power supply is easier to obtain than the gas source and the liquid source, Valve Control Actuators and the wiring and maintenance of the wires are also better than the compressed air and liquid ...

Advantages

1. Strong applicability, not affected by ambient temperature

2. Wide range of output torque

3, easy to control, can freely use DC, AC, shortwave, Valve Control Actuators pulse and other signals, suitable for amplification, memory, logical judgments and calculations, and other work

4, can realize ultra miniaturization

5. Mechanical Self-Locking

6. Easy installation

7. Convenient Maintenance and Repair

A valve driver is a device used to operate a valve and connect it to a valve. The device can be driven by a power source of manual, electric, pneumatic, hydraulic or combination forms, Valve Control Actuators and the motion process can be controlled by the size of stroke, torque or axial thrust. Choice of valve actuator to fully understand the type and performance of the valve actuator, depending on the type of valve, Valve Control Actuators the working specifications of the device, and the position of the valve in the pipeline or device.

At present, our country has two main valve driver connection standard, namely GB/T 12222 "multiple rotary valve Drive Connection" and gb/t12223 "partial rotary valve Driver Connection", Valve Control Actuators the two standards are equivalent to the ISO 5210 and ISO5211 standard respectively.

"Multi-rotating valve drive connection" is mainly applicable to the valve, the cut-off valve, throttle valve and diaphragm valve with the driving device and the connection size.

"Part of the rotary valve drive connection" is mainly applicable to the ball valve, butterfly valve and plug valve with the driving device and valve connection size.

The valve actuator can be divided into two kinds of straight stroke and angular travel according to the movement mode. The direct travel drive device is a multiple rotary valve driver, Valve Control Actuators which is mainly applicable to all kinds of gate valves, globe valve and throttle valve, and so on, the angular stroke drive device, which is only a part of Rotary 90° turning angle, is mainly applicable to all kinds of ball valves, butterfly valves and so on.

The valve drive can be divided into manual (handle handwheel type, Spring lever type) according to energy form. Electric (electromagnetic, motor-type), pneumatic (diaphragm type, cylinder type, vane type, air engine type, film and ratchet combination), liquid (hydraulic cylinder type, hydraulic motor type), linkage (electro-hydraulic linkage, gas-liquid linkage), and other forms.

In various types of valve drivers, the electric device dominates, it is mainly used in closed-circuit valves.

The pneumatic device is widely used in explosion-proof requirements, Valve Control Actuators in which the membrane-type pneumatic device is mainly used in the regulating valve. The hydraulic device is widely used in the natural emergency shut-off valve and the wellhead discharge valve on the long-distance pipeline.

Hand-operated handwheel, most of which are installed on low, medium pressure cut-off valves and gate valves;

The handle is used for high-pressure and ultra-high pressure cut-off valve, Valve Control Actuators ball valve and Plug and other valves.

Gas-liquid linkage device, used in gas transmission pipeline, no power in the field, its power source is a pipeline of gases.
