What is the hydraulic valve driver?
used in industrial industries, including water, oil and power plants, valve drivers provide automated valve operation along the pipe system. The use of activated valves allows technicians to remotely control the entire process of the process system, which limits the requirement for direct interaction. There are different types of drivers determined by their operational mechanisms; They are either pneumatic, electric or hydraulic valve control. The drive of the hydraulic valve converts electrical signals into fluid pressure in the hydraulic cylinder to ensure movement. If necessary, the engineers can easily equip the existing controls of the manual operating valve to equip the hydraulic controls. This control style provides rotary movement by adjusting hydraulic pressure within the piston arm. It can turn the valve flange by pulling the arm and return to the original position by inserting the arm. With this limited movement, the hydrauli is not used to control the multi -rotation valveClea drives. The first is multitutures that control the gates. These valves can rotate a complete 360 degree rotation and are controlled by electric valve drive due to unlimited one -way rotation required.
Partial drivers with partial turnover work in a similar way to multititus drivers, but must only rotate at an angle of approximately 90 degrees. The butterfly valves are the most common type of controlled partial drivers, which can be controlled either by an electric, pneumatic or hydraulic valve control. One of the key areas in which multititus and partial rotation controls differ are their tension resistance requirements. Since the multiturn valves are not limited in their rotation, the controller must be able to withstand the tensile force it experiences. Valves with partial turnover are supported by parts of the valve body and are therefore not obliged to withstand tension.
tThe rim type of valve control is a linear driver. These linear drivers operate by blocking the pipeline and are therefore most commonly visible on control valves. This type of valve operates by pressing the plug into the pipes and by developing a similar level of force to the tension acting on the valve surface. Most controlled valves are also equipped with hand wheels to allow manual control if necessary.
