Working Principle

The pneumatic actuated butterfly valve operates through a simple yet reliable mechanism:

• 1. Actuator Operation: Compressed air is supplied to the pneumatic actuator. For double-acting actuators, air enters one side to open the valve and the other side to close it. For spring-return actuators, the valve is opened or closed by air pressure and returns to the fail-safe position when air supply is lost.
• 2. Valve Operation: The actuator drives the stem, which rotates the disc 90° from fully closed to fully open. The disc provides bi-directional sealing against the seat.
• 3. Control Options: The valve can be controlled by a solenoid valve (on/off control) or a positioner (modulating control with 4-20mA or 0-10V signal).

자주 묻는 질문

1분기: What is the difference between pneumatic and electric actuators?

에이: Pneumatic actuators are driven by compressed air, offering fast response, high thrust, and excellent explosion-proof capabilities; they are suitable for hazardous areas and frequent operation. Electric actuators are powered by electricity, offering higher precision and eliminating the need for an air supply; they are suitable for locations lacking compressed air systems. The choice depends on on-site air supply conditions and control precision requirements.

2분기: What is the difference between metal-to-metal (hard) sealing and soft sealing?

에이: Metal-to-metal sealing utilizes metal-on-metal contact, capable of withstanding temperatures up to 600°C; it is wear- and corrosion-resistant, making it suitable for high-temperature steam, hot oil, and abrasive media. Soft sealing (EPDM/PTFE/Viton) provides bubble-tight sealing but has a limited temperature range (typically ≤200°C). The choice depends on the medium’s temperature, 압력, 부식성.

3분기: Do pneumatic actuators support explosion-proof requirements?

에이: 예. Pneumatic actuators do not generate electrical sparks and are inherently explosion-proof. When paired with explosion-proof solenoid valves and positioners, the entire valve assembly meets explosion-proof zone requirements (Exd/Exia), making it suitable for hazardous environments such as petrochemical plants.

4분기: How is automated control achieved with pneumatic butterfly valves?

에이: Pneumatic butterfly valves achieve on/off control via solenoid valves and modulating control via positioners (using 4-20mA or 0-10V signals). The system consists of an air preparation unit (filter-regulator + lubricator), a solenoid valve or positioner, and a pneumatic actuator, allowing for seamless integration into DCS, PLC, and SCADA systems.

Q5: 웨이퍼 스타일과 러그 스타일 버터플라이 밸브의 차이점은 무엇입니까??

에이: 웨이퍼 스타일 버터플라이 밸브는 관통 볼트를 사용하여 두 플랜지 사이에 설치됩니다.; they are compact, 경량, 그리고 비용 효율적. 러그 스타일 버터플라이 밸브는 양쪽에 나사형 러그가 있습니다., 플랜지에 개별적으로 볼트로 고정 가능; this supports single-sided isolation, enabling the removal of downstream piping without draining the system. The choice depends on installation space and maintenance requirements.
