Topoac Automation Control valve are valves used to control conditions such as flow, pressure, temperature, and liquid level by fully or partially opening or closing in response to signals received from controllers that compare a "setpoint" to a "process variable" whose value is provided by sensors that monitor changes in such conditions.
The opening or closing of control valves is done automatically by electrical, hydraulic or pneumatic actuators. Positioners are used to control the opening or closing of the actuator based on electric, or pneumatic signals. These control signals, generally based on 3-15psi (0.2-1.0bar), more common now are 4-20mA signals for industry, 0-10V for HVAC systems.
Automation control valve consists of three main parts in which each part exist in several types and designs:
• Valve's actuator
• Valve's positioner
• Valve's body
Topoac automation control valve have the variant segmented ball valve, full ball valve, ceramic lined ball valve, knife gate valve, three ways Ball Valve and butterfly valve.
