Description

Pneumatic Wafer Butterfly Valve PN10/16/CL150

Features of Pneumatic Butterfly Valve

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.

Application of Pneumatic Wafer Butterfly Valve

1. Water treatment facilities: For water treatment projects, pneumatic butterfly valves help regulate the inflow of raw water, the flow rate of treated water, and the outflow of wastewater.
2. Petrochemical industry: The petrochemical industry requires precise control of fluid flow and pressure. This makes pneumatic wafer butterfly valves ideal for regulating fluid flow in refineries, chemical tanks, gas processing units, and other facilities. Its rugged design can withstand the high temperatures and pressures common in this industry.
3. Power generation: During the power generation process, steam turbines need to precisely regulate inlet and outlet flows. Pneumatic butterfly valves minimize energy losses by regulating steam pressure.
4. Chemical industry: In chemical plants, pneumatic wafer butterfly valves can be used in processes such as mixing, separation, reaction, filtration, transportation, and storage of chemicals. Their function is to seal and control the flow of corrosive, toxic, or hazardous substances.
5. Food processing industry: Pneumatic butterfly valves are suitable for conveying, filling, batching, and metering operations in factories that produce beverages, dairy products, canned foods, and baked goods.
6. HVAC system: Butterfly valves regulate cold and hot water in HVAC systems. Automated operation improves efficiency and reduces manual intervention.
