Uses and characteristics

A uses a right angle turn structure, with the valve positioner supporting the use of proportional control can be achieved; V type valve adjustment for a variety of occasions, with a rated flow coefficient, adjustable ratio, good sealing effect, regulate the performance of zero sensitivity, small size, can be vertical horizontal installation. It is suitable for controlling medium such as gas, steam and liquid.

B features: the structure of a right angle turn, by type V valve, pneumatic actuator, positioner and other accessories; there is a similar percentage of the inherent flow characteristics; dual bearing structure, the starting torque is small, with excellent sensitivity and speed sensors; superior cutting ability.

C, pneumatic piston actuator uses compressed air as power source, through the movement of the piston to drive the crank arm 90 degrees rotation, to achieve automatic valve opening and closing. Its components are: adjusting bolt, actuating mechanism box, crank arm, cylinder body, cylinder shaft, piston, connecting rod and universal shaft.

The working principle of D and pneumatic control valve: the pneumatic control valve is composed of executive mechanism and regulating mechanism. The actuator is the thrust component of the regulating valve, which generates the corresponding thrust according to the pressure of the control signal, and drives the regulating mechanism to act. The valve body is the regulating component of the pneumatic control valve. It contacts the regulating medium directly and regulates the flow of the fluid.
