Frequently Asked Questions

Common questions about valve design, performance, and automation for this application.

Which industrial valves are used in vacuum applications?

Ball valves, butterfly valves and other suitable valve designs may be used in vacuum systems, depending on the required vacuum level, operating conditions and isolation requirements. The selected valve must provide suitable sealing performance for the intended vacuum service.

How do I select the right valve for a vacuum system?

Consider the required vacuum level, operating pressure, pressure differential, temperature, process medium, valve size and leakage requirements. Also verify seat and seal compatibility, outgassing considerations where relevant, and the manufacturer's specified operating limits.

What is the difference between a vacuum valve and a standard industrial valve?

A vacuum valve is selected or designed to meet specific requirements for low-pressure operation and gas leakage control. A standard industrial valve should not automatically be assumed suitable for vacuum service without verifying its sealing performance and suitability for the required vacuum level.

Which valves are suitable for high-vacuum applications?

High-vacuum applications require valves with sealing performance, materials and construction suitable for the specified vacuum range. Consider leakage rate, outgassing, surface cleanliness and connection design where relevant. Confirm the valve's suitability with the manufacturer before selection.

How can valve leakage be reduced in vacuum systems?

Select valves with suitable seats, seals and connection arrangements for the required vacuum level. Correct installation, clean sealing surfaces, proper gasket selection and routine inspection can help reduce leakage. Confirm whether the application requires a specified leak-rate test.

Can ball valves be used in industrial vacuum systems?

Some ball valves may be suitable for industrial vacuum applications, depending on their design, seat arrangement and sealing performance. Verify the required vacuum level, leakage limits, operating temperature and process-medium compatibility before selecting a valve.

Which materials are suitable for vacuum valves?

Material selection depends on the process gas or fluid, temperature, cleanliness requirements and potential outgassing. Evaluate the valve body, trim, seats, seals and gaskets for compatibility with the application and the required vacuum performance.

What is the difference between vacuum pressure and positive pressure?

Positive pressure is pressure above atmospheric pressure, while vacuum conditions involve pressure below atmospheric pressure. Vacuum valve selection must account for the pressure differential across the valve and the required sealing performance under the intended operating conditions.

Which valves are used in vacuum conveying and industrial processing systems?

Suitable isolation valves, butterfly valves and other application-specific designs may be considered for vacuum conveying and process equipment. Selection depends on the conveyed material, particle characteristics, system pressure, sealing requirements and the risk of material accumulation.

What technical details are required when purchasing valves for vacuum service?

Provide the valve type, size, required absolute pressure or vacuum level, operating temperature, process medium, pressure differential, material requirements, end connections, leakage limits, actuation details and quantity. Include relevant drawings and system specifications where available.
