Import Electric Ventilation Butterfly Valve — Buy in wholesale FOB from Supplier in China

The electric ventilation butterfly valve from Tianjin Freya Automation Technology Co., Ltd. combines an 802 series quarter-turn actuator with a butterfly valve body, designed for precise airflow control in industrial ventilation systems. The nominal pressure rating is 0.6 MPa, with a leakage rate controlled within 2% of maximum flow volume. The valve body and seal ring are fabricated from the same material to ensure consistent thermal expansion and sealing performance. It is intended for use in industries including metallurgy, environmental control, and manufacturing facilities requiring regulated airflow.

The valve is constructed from steel plate welded into a compact body, minimizing weight and space requirements. An oil sealing ring is integrated into the valve body to eliminate visible gaps and reduce leakage. The actuator provides low driving torque, enabling smooth on-off operation and resistance to sticking caused by thermal expansion. No material grade is specified for the body or seal, but standard materials for such valves include carbon steel, stainless steel 304, or ductile iron, depending on the medium and temperature conditions.

This valve is commonly purchased by HVAC system integrators, waste treatment plants, and industrial furnace operators who require automated flow regulation. Buyers typically specify this valve for applications where manual control is impractical or where integration with building automation systems is required. Trade terms are not listed, but standard export packaging includes anti-corrosion coating, plastic caps on flanges, and wooden crate shipment. Buyers should confirm compatibility with the operating medium, temperature range, and required actuator voltage before ordering.

Tianjin Freya Automation Technology Co., Ltd. is located in Zhongbei Town, Xiqing District, Tianjin, a region known for industrial automation component manufacturing. The supplier is classified as harbor-trusted, indicating verified export compliance and shipping capability. The listing does not state company size, production capacity, or client names. No certifications such as ISO 9001, CE, or API are mentioned, nor are any factory inspection reports or quality control procedures described.

The company focuses on automation valves and actuators, with this product being one of several listed. There is no mention of R&D capabilities, testing equipment, or in-house material certification. Buyers should request documentation on material traceability, pressure testing records, and actuator calibration certificates. The absence of response rate and average response time suggests limited customer service infrastructure, requiring proactive follow-up during procurement.
