What are the advantages, disadvantages and application scopes of ball valves?

I. Core Advantages of Ball Valves 1. The fluid resistance is extremely small The resistance coefficient of full-bore ball valves is comparable to that of pipes of the same length and is much lower than that of stop valves or gate valves. They are particularly suitable for conveying systems with high viscosity or granular media (such as slurries in the chemical industry). 2. Outstanding operational efficiency

The differences between electric valves and pneumatic valves

Electric valves and pneumatic valves differ in terms of power sources, control performance, applicable scenarios, and maintenance costs, as follows: Power source Electric valve: It uses an electric motor as the power source and drives the opening and closing of the valve through the motor. Electric motors usually use mains electricity or other DC power sources. As long as there is a stable power supply, electric valves can work normally.

Working principle of regulating valve

Regulating valve is a key equipment used in industrial processes for precise control of fluid (gas, liquid or steam) flow rate. Its working principle is based on adjusting the flow rate by changing the cross-sectional area between the valve core and valve seat. The following is a step-by-step explanation of its core working principle:
