{"product_id":"electric-ventilation-valve","title":"Electric Ventilation Valve","description":"\u003cp\u003eElectric 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.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eProduct Features:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli data-sourcepos=\"17:1-17:144\"\u003eTemperature range is virtually unlimited, allowing for the use of a wide variety of materials and enabling operation at ambient temperatures.\u003c\/li\u003e\n\u003cli data-sourcepos=\"18:1-18:75\"\u003eThe valve plate and retaining ring create a tight seal, reducing leakage to approximately 1%.
