A Guide For Valve Selection
The operation of a driven ball valve is similar to the manual counterpart, but a drive is mounted on this valve instead of a lever to drive the stem, which in turn rotates the ball to provide the desired operation. Since the actuator receives a signal from the location of the remote control, depending on the position, it will rotate to start or stop the fluid flow through the ball valve. Activated ball valves are sometimes equipped with an electric or pneumatic drive instead of manual operation of the handle to switch the valve on or off.
This article is only a summary of the different types of electric ball valves; Design variations are as numerous as applications. Activated ball valves are extremely useful in terms of production and safety. Parts will break and potentially damage workers nearby if a machine tries to continue working when pressure or temperature levels are dangerously high.
A two-way solenoid provides a normally closed or normally open configuration. When it is debunked, the valve returns to its normal position via a spring. Even on a 3-way solenoid valve, the device has only two states, energized and voltage-free, regardless of portability. Here too, the valve returns to its normal state via a spring when it is switched off.
You need to perform power control, you can choose the worm, band or electric drive with V-shaped opening control ball valve A solenoid valve is activated by activating an electric coil, which induces magnetism and moves an iron piston from left to right. The small holes revealed by the moving piston allow the medium to travel in the desired direction. A driven valve uses motors or air to rotate the valve; Large valves often use magnetic valves to divert the air pressure to an actuator to open them. Although actuators and ball valves are different components, they are often used together. Therefore, it is more beneficial to obtain them as a package to ensure compliance.
No additional shut-off valves are required when using a V-ball valve, saving user costs and reducing the total number of components in the system. The precisely crafted V-balls, available at 60 ° and 90 °, offer equal percentage current characteristics, corresponding current performance of a balloon valve. As the ball rotates, the desired flow rates can be achieved by placing the ball somewhere between 0 ° and 90 °. Because V-ball valves use smaller drives, their response time is much faster than balloon valves that use large aperture drives. Flow-Tek control ball valves are designed to provide peak current features that are significantly higher than comparable balloon valves. The inherent flow pattern of ball valves increases flow rates and in many applications valves smaller than the size of the tube can be used.
This means that, under ideal operating conditions, the number of opening / closing cycles performed by the device before maintenance or replacement is required will demonstrate larger orders of magnitude on a solenoid. The pneumatically driven ball valve is widely used in industrial automatic control systems such as oil, chemicals, light industry, pharmacy, paper production, etc. The pneumatic ball valve is mainly used to cut or connect the medium to the tube. Compared to other types of valves, the pneumatic ball valve has a angle impact torque, opens quickly, is stable and reliable and is generally applicable, etc.
Activated ball valves are used in applications where automatic valve control is required. Unlike manual valves, which have to be manually rotated with a handle or gearbox, the active valves open and close automatically after receiving a control signal, using a drive. Depending on the system requirements and resource availability, this drive may be an electrically controlled motor, pneumatic device or hydraulic device to rotate the valve before use. Differences in this power supply result in different designs, each design has different advantages and disadvantages for specific applications. In addition to the torque generator component, an actuator may contain functions such as manual position and override indicators.
When equilibrium conditions are obtained, the movement of the stem stops and the flap is placed to prevent further reduction of the pressure of the actuator. The metal to metal seats of the Globe valve allow material to escape through the valve even when closed. V-ball valves have soft seats with airtight bubble closure and can control or disable the two-way flow.
There is no need to take the stage or the high altitude and bring dangerous manual control, which saves human resources, time and safety enormously. The operating principle is to unlock or lock the valve by rotating the valve core. There are different types of power supplies for operating an electric ball valve.
Designed with flexibility in process conditions in mind, the features of CV and control change easily by changing the ball. Activated ball valves are incredibly useful for both production and safety reasons. If a machine tries to continue working when pressure or temperature levels are dangerously high, the parts may break and potentially van bi điều khiển bằng khí nén damage nearby workers. The powered ball valves and sensors that respond to those sensors enable a machine to self-regulate and respond to these conditions before they become disastrous. Successful implementation of a powered ball valve can reduce production loss, recovery time and injury by responding quickly if necessary.
