Description

Pneumatic Wafer Butterfly Valve PN10/16/CL150

Composition and function of the triplex pneumatic butterfly valve

Filter

The filter removes impurities and moisture from compressed air. This keeps the air entering the pneumatic actuator pure. It reduces blockages in the pipeline and minimizes internal wear on the actuator.

Pressure Regulating Valve

The pressure regulating valve controls and stabilizes the air pressure entering the actuator. This prevents abnormal operation of the actuator and excessive wear on the pneumatic wafer butterfly valve from pressure fluctuations. By maintaining the air pressure within a safe range, it extends the actuator’s lifespan and keeps it running smoothly.

Lubricator

The lubricator adds a precise amount of lubricating oil to the air source. This reduces internal friction in the pneumatic actuator and allows the components to operate smoothly. For frequent opening and closing, lubrication is essential. It extends equipment life and ensures the actuator functions of pneumatic wafer butterfly valve properly.

When choose a pneumatic actuator, there are several important issues to consider:

Match: Make sure the pneumatic actuator selected matches the required valve size and type to ensure the system will function properly.
Control mode: According to the process requirements and control needs, select the appropriate pneumatic actuator control mode, such as double-acting or single-acting actuator.
Environmental conditions: Consider the environmental conditions of the installation location, including temperature, humidity, corrosion, etc., and select pneumatic actuator materials and protection levels that meet the requirements.
Control signals: Determine the control signal types and interface standards required so that the pneumatic actuator is compatible with the control system.
