1. What are the three main factors to consider when selecting an actuator? 1) The actuator’s output must exceed the valve's load and be appropriately matched. 2) When checking standard combinations, ensure that the allowable pressure differential specified for the valve meets process requirements. For high pressure differentials, calculate the unbalanced forces on the valve core. 3) Consider wheth...

In automated process control systems, the regulating valve is a crucial and indispensable component, often referred to as the "hands and feet" of process automation. It is one of the terminal control elements in an automatic control system. The regulating valve consists of an actuator and a valve body. From a hydraulics perspective, the regulating valve is a throttling element with variable local ...

In the valve industry, shut-off valves are widely used in various industrial piping systems due to their excellent regulation and sealing capabilities. However, a key aspect often overlooked during the installation of shut-off valves is their installation orientation. In reality, shut-off valves have specific directional requirements. Proper installation direction is not only crucial for the valve...

Ball valves are widely used in various industrial sectors due to their simple structure, excellent sealing performance, and ease of operation. However, during long-term use, ball valves may develop leaks. Leaks not only lead to the waste of media but can also disrupt the normal operation of the system and even pose safety risks. Common Reasons 1. Aging or Damage of Sealing Materials The sealing pe...

A ball valve does not always need to be fully open, but whether it should be fully open or not depends on the application and the design of the valve. 1. Designed for On/Off Control Ball valves are typically designed for full on/off control, meaning they function best when they are either fully open or fully closed. This is because they allow for minimal resistance to flow when fully open and prov...
