Application of a New Type of Intelligent Valve Positioner in Control Valves

2016-02-22

Control valves are primarily classified into electrically actuated regulating valves and pneumatically actuated regulating valves, depending on the drive method, to meet different operating conditions and process requirements. Electrically actuated regulating valves are typically driven directly by angular-stroke electric actuators, with valve opening controlled via 4–20 mA or 0–10 V analog signals, thereby achieving the desired control objective. Valves commonly used for angular-stroke control include ball valves and butterfly valves. While electric control valves are simple to operate and do not require compressed air, they suffer from slow response times and relatively poor control accuracy and regulation performance, limiting their application to environments where high control accuracy is not required and operational frequency is low. In comparison, pneumatic

Common Fault Causes and Countermeasures for Smart Valve Positioners

2016-02-22

Fault 1: Slow output response of the positioner Causes: 1. Leakage in the input air chamber; 2. Blockage in the constant orifice; 3. Leakage in the air supply line; 4. Scratches on the baffle or improper baffle positioning Corrective measures: 1. Replace the damaged diaphragm; 2. Clean the orifice; 3. Locate and repair any leaks; 4. Replace the baffle or readjust it Fault 2: No output pressure from the positioner (the baffle does not move after an input signal) Causes: 1. Incorrect connection of the positive and negative terminals; 2. Excessive air supply pressure; 3. Open circuit in the solenoid assembly coil Corrective measures: 1.

Selection of Control Valves

2016-04-29

Control valves are the actuators in automated control systems, and their performance directly affects the control quality of the system. With the continuous advancement of industrial automation, control valves have become integral to every aspect of production, playing a pivotal role in ensuring stable operation, optimizing control strategies, and effectively managing maintenance and overhaul costs. Why is it crucial to select the right control valve? There’s a common saying in the automation industry: “Nine out of ten valves leak.” Selecting the appropriate control valve is one of the most challenging tasks in instrument selection, particularly in process control applications involving complex processes and media, where the selection challenges are even more pronounced. Proper application of control valves
