Pneumatic Control Valve is designed to endure a varying degree of temperature, pressure, amount of fluid, and control levels. The Pneumatic Diagram Type actuator of the operation unit activates the valve with great precision, enabling optimal control over the system. Some other special properties include the emergency handle which enables control in emergency situations, and the balanced structure which minimizes influence from differential pressure. The valve can also be modified to suit different types of control and allows precision control.
