Control Valves with Valve Positioner
The controller system sends an input signal directly to the valve positioner and controls the actuator movement, through the actuator to control the valve opening. The positioner senses this exact movement and communicates with it for smooth operation.
How to Select Oxygen Control Valve in Chemical and Steel Plants?
Regarding the provisions in the “Regulations on the Safe Operation of Air Separation Units”, the safe operation of oxygen valves should be emphasized, and safety precautions should be taken to avoid explosions due to excessive flow rate and other reasons. This article introduces the importance of coal chemical projects in the selection of oxygen control […]
Power Plant Valves and Solutions
Thermal Power Station Process Classified by total installed capacity for power plant: Classified by steam pressure and temperature for power plant: Power Plant Valves 1. Power Plant Valves Used in Condensing System a) The condenser circulation control valve is the same as most centrifugal pumps. The condensate pump needs a minimum flow to avoid overheating and protect the pump from cavitation damage. Therefore, a circulation loop is added from […]
How to Calibrate a Control Valve
There’s no doubt that having a well-calibrated control valve is crucial for any industrial process. After all, without proper calibration, you could end up with costly mistakes and subpar performance. A control valve calibration is an important process for industry to get right. By calibrating a control valve, it ensures that the valve is functioning at peak efficiency. This in turn leads to better overall performance in the industry process. Having a properly calibrated control valve can save time and money by optimizing the process.

Top Mistake to Avoid While Installation Control Valves
A control valve is a regulating device that is utilized for the manipulation and regulation of the pressure flow of different materials used in industry. These materials include steam, gas, hot water, and different chemicals which are processed to manufacture end products. The control valve is a vital element of the control process loop in […]
How to Select Electric Actuator for Control Valves?
As the most important control element in the industrial process-control valves, its driving commonly used in electric and pneumatic type. The electric control valve simply to say just a control valve body assembly with electric actuator.
3 Typical Systems of Steam Pressure Reducing Station
This post is explain 3 typical systems of steam pressure reducing station.
What are the Different Types of Control Valves in Industries?
We know control valves are like the ‘final control element’ in the process of the industry. The main function of the control valve is to regulate the flow capacity or downstream pressure of a fluid. The control valves are usually installed with an actuator, positioner, handwheel, solenoid valve, limit switch, or other accessories.
How control valve factories in China can provide such a cheap price?
Don’t doubt your eyes, it’s all true! Maybe this happened to you too. The low price has gained your trust, but the damage done to you is far more than money, more is the destruction of your business reputation. Here is an example we have met. I always have a question that why some suppliers […]
What Is The Difference Between Pressure Control Valve and Flow Control Valve
The flow control valves are used for controlling and adjusting the fluid or gas flow through the system. The pressure control valve is used to regulate the pressure of a fluid passing through the pipe.
6 Typical Applications of Fusible Link Valves and How It Work
Fire safety fusible link valve-the fire safety ball valve with automatic thermal shutdown device (Thermal Shut-Off Valves), also known as fire cut off valve, fire fuse valve, high-temperature fuse valve, without a power supply or air source. It’s a kind of fire safety fire protection, the device is designed to automatically close the valve in the event of high temperature or fire. The product has high-quality ball valves with API 607 fire protection certification.
