What Is Johnson Controls Control Valves?
-
Johnson Controls control valves are the most popularly used control valves in the oil and gas sector. This is because they are both dependable and efficient and amount to an optimized result.
The major responsibility of a control valve is to alternate the fluid rate to reach its optimal capacity. They are responsible for preventing fluid spillages in the industry.
A control valve carries out this responsibility because of the coherence of its different parts, with each part having its role to play. It consists of the Body-The housing compartment for the transmission elements, Actuators-Which serve as the CPU of the control valve, ensuring that it is open and close as when due, and finally, the Positioners- which are responsible for maintaining the accuracy of the opening through their interface with the actuators.
Today’s article is aimed at laying out the different benefits positioners offer to the Johnson Controls Control Valves after briefly explaining the different types of Control valves. Enjoy.
Types of Control Valves
Control Valves are made of two types, all classified according to the mechanism of action of the parts. They include:
Based on Types of Actuators
In this classification, the control valves generate energy either from air pressure or electrical currents.
- Pneumatic Control Valves: This type of control valve consists of pneumatic actuators. They work in conjunction with pneumatic positioners, which direct the right amount of air pressure into the pneumatic actuators to elicit action.
- Electric Control Valves: They make use of electrically generated energy to open or shut the valve. Both the positioners and actuators of this type are automated.
Based on Types of Positioners
There are different types of control valves based on the different positioners.
- Pneumatic Control Valve: Positioners form the bridge between actuators and the body. The particular type of positioners encompasses the total air pressure before reducing the air pressure to the right amount and then passing it to the actuators to elicit action.
- Electro-Pneumatic Control Valves: They make use of the combination of air pressure and electricity.
- Digital Control Valves: This type works by using a microprocessor that converts analog signals into digital transmissions for the actuator.
Benefits of Positioners to Johnson Controls Control Valve
Precision: Positioners form a bridge between the body and actuators, so they offer precision in the action of control valves eliminating redundancies.
Quick response: Because they know the exact position of the set point, they reduce the time to get to it.
Accuracy: They offer stability to the control valve by ensuring consistent set point values.
Flexibility: They have a fail-safe configuration that ensures flexibility of set point values, all in a bid to meet the optimal capacity. They also prevent wear and tear of the control valve.
