Product DescriptionA pneumatic regulating valve is a valve that
uses compressed air as a power source to achieve automatic control.
It consists of an actuator and a regulating mechanism. The actuator
is the thrust component of the regulating valve, which generates
corresponding thrust according to the size of the control signal
pressure and drives the regulating mechanism to act. The valve body
is the regulating component of the pneumatic regulating valve,
which directly contacts the regulating medium and regulates the
flow rate of the fluid.ApplicationPneumatic regulating valves are
widely used in industries such as natural gas, oil, chemical,
metallurgy, paper-making, electricity, mining, printing and dyeing,
biopharmaceuticals, daily chemicals, food and beverage, water
treatment, and air handling for fluid automatic control or
regulation. They are commonly used in conjunction with automated
pneumatic instruments.Working principle1. In the closed position,
the ball is pressed against the valve seat by the mechanical
pressure of the valve stem.2. When the hand wheel is turned
counterclockwise, the valve stem moves in the opposite direction,
and the angular plane at the bottom makes the ball disengage from
the valve seat.3. The valve stem continues to lift and interacts
with the guide pin in the helical groove of the valve stem, causing
the ball to start rotating without friction.4. Until it reaches the
fully open position, the valve stem is raised to the limit
position, and the ball rotates to the fully open position.Product
