Before choosing the right plate ball valve, you first need to understand what is the plate ball valve and its characteristics. Plate ball valve is a commonly used control valve, which completes the switching operation by rotating the ball. Compared with other types of valves, plate ball valves have the following characteristics:
Excellent sealing performance: The use of ball sealing, can achieve good sealing effect, even in high temperature, high pressure and other harsh conditions can also maintain good sealing performance.
Low fluid resistance: Because the channel of the ball is the same as the valve body, the resistance of the fluid when passing is small, which can reduce energy consumption.
Simple structure, small size: The structure of the plate ball valve is relatively simple, the volume is relatively small, and it can adapt to the narrow installation space.
Fast switching operation: The ball can be rotated 90 degrees to achieve fast switching operation, open or close time is short.
Choosing the right plate ball valve needs to consider the following key factors:
Working medium: First of all, you need to understand the working medium to be controlled, including fluid properties, temperature, pressure, etc. Select the appropriate valve body material and sealing material according to different working conditions to ensure that the valve can run stably and reliably during the working process.
Valve size: Select the appropriate valve size according to the size of the piping system. The size of the valve should match the flow rate of the piping system to ensure smooth flow of fluid through the valve.
Valve type: Select the right valve type according to the work requirements. Common plate ball valves are full diameter ball valves and straight through ball valves. Full-diameter ball valves are suitable for occasions where maximum flow is required, while straight-through ball valves are suitable for occasions where minimum resistance is required.
Valve material: Select the appropriate valve material according to the nature of the working medium. Common valve materials include stainless steel, carbon steel, cast iron and so on. For corrosive media, you can choose a valve made of corrosion-resistant materials.
Actuator: Select the appropriate actuator according to the job requirements. Common actuators are manual, pneumatic and electric actuators. Manual actuators are suitable for occasions with low normal operating frequency, and pneumatic and electric actuators are suitable for occasions requiring frequent operation or remote control.
Regulatory requirements: According to the process requirements and workplace regulatory requirements, select the appropriate plate ball valve. Some industries, such as petroleum, chemical, etc., have high safety and reliability requirements for valves, and need to choose products that meet relevant standards and specifications.
Price and cost performance: Finally, it is necessary to consider the price and cost performance of the valve according to the economic budget. To choose products with good quality, long life and stable performance to ensure the reliable operation of the valve. But at the same time, it is also necessary to take into account the price and choose a valve with a higher cost performance.
To sum up, the choice of the right plate ball valve needs to consider the working medium, valve size, valve type, valve material, actuator, regulatory requirements and price and other factors. Only after considering the needs of all aspects, can we choose the plate ball valve suitable for our own process system.
