Electric Ventilation Valve

Electric ventilation butterfly valve, also known as electric flow indicator regulating butterfly valve, is composed of a quarter-turn electric actuator and a butterfly valve. It adopts a new structural form of a centerline disc plate welded with a short structural steel plate. It is suitable for two-position cut-off occasions. The valve body is made of the same material and processed into a sealing circle. Its applicable temperature depends on the choice of valve body material. The nominal pressure is less than 1.0 MPa. It is mainly used in industrial, metallurgical, flue gas desulfurization, and environmental protection pipelines as a gas medium to regulate flow or cut off. It is not suitable for high temperature, high pressure, corrosion-resistant, and wear-resistant industries.

Product Features:

• Temperature range is virtually unlimited, allowing for the use of a wide variety of materials and enabling operation at ambient temperatures.
• The valve plate and retaining ring create a tight seal, reducing leakage to approximately 1%. This level of leakage is considered acceptable for flue gas treatment applications.
• The ventilation butterfly valve offers cost-effective advantages due to its simple design, low torque requirements, and compact actuator.
• The valve’s simple structure ensures long service life and easy maintenance.
• Innovative design results in a lightweight, fast-acting valve with a rational structure.
• The valve requires minimal operating torque, making it easy and efficient to operate.
• By selecting suitable materials, the valve can accommodate low, medium, and high temperatures as well as corrosive media.
