Comparison of the functional advantages and disadvantages of Plug Valve

1. Determine the valve type based on comprehensive economic effects

There are several types of applicable valves that meet the above functional requirements. At this time, a certain valve type should be determined based on the economic effects. To this end, we believe that at least the following issues should be considered:

1) High reliability
①Simple structure;
②High reliability. Here we need to change the past erroneous practice of one-sided pursuit of performance indicators and neglect of reliability.
2) Long service life.
3) Maintenance is easy and spare parts are available from sources.
4) The product is reasonably priced and has good performance and price.
2. Preferred order of Plug Valve types
Based on the functional advantages and disadvantages of Plug Valve and the above points, the preferred order of Plug Valve is as follows:
① Full-function ultra-light Plug Valve → ② Butterfly Valve → ③ Sleeve valve → ④ Single-seat valve → ⑤ Double-seat valve → ⑥ Eccentric Rotary Valve → ⑦ Ball Valve → ⑧ Angle valve → ⑨ Three-way valve → ⑩ Diaphragm Valve.
3. Selection of execution agency
The main considerations in selecting an actuator are:
①Reliability;
②Economy;
③Smooth action and sufficient output force;
④Weight and appearance;
⑤Simple structure and easy maintenance.
