As a core component of automatic control systems, valve actuators are widely used in industries such as petroleum, chemical engineering, water treatment, food, and pharmaceuticals. They can precisely control the opening and closing actions of valves according to control signals, thereby regulating the flow and pressure in pipelines.
Common types of actuators include: electric valve actuators, pneumatic valve actuators, and hydraulic valve actuators. Regardless of the type, lubrication is a key factor in ensuring stable operation, rapid response, and long service life of the equipment.
Where are the key lubrication parts? Generally, valve actuators involve two main oil-using parts:
1. Internal gearbox: The core of the actuator's power output, responsible for driving the valve action;
2. Interface sealing ring: A key area to prevent medium leakage, which needs to have good sealing and lubricating functions.
How to choose the right lubricating grease for valve actuators?
Viscosity matching: Select a lubricating grease with an appropriate viscosity grade according to the actuator's working environment (temperature, pressure, operating frequency) to ensure it does not get stuck at low temperatures and does not at high temperatures. Temperature resistance: Especially for electric or hydraulic actuators, the temperature rise during operation is obvious, so lubricating grease with stable high and low temperature resistance should be selected. Strong oxidation resistance: Not easy to deteriorate after long-term use, prolonging the maintenance cycle and reducing operating costs. Compatibility with sealing rings: Lubricating grease used for sealing rings must pay special attention to compatibility with materials such as EPDM and NBR to avoid problems such as swelling, hardening, and leakage. Good water resistance: Especially for valves used in scenarios such as water treatment and steam control, the lubricating grease is required to have excellent waterproof and sealing capabilities.
