Ningbo, China — Ningbo Felo Valve Factory recently completed a successful installation and operation test of its DN200 stainless steel gate valve in a high-pressure petrochemical pipeline system, further demonstrating the company’s engineering reliability and precision control technology.
During testing, the actuator’s red indicator light signaled an active closing sequence, with the valve stem rotating clockwise to lower the gate plate into the valve seat. The transparent visualization revealed the gate’s controlled downward motion, approximately two-thirds engaged, ensuring a smooth transition from open to closed position.
The pipeline system operates under a pressure of 2.5 MPa, as shown on the adjacent blue pressure gauge. Despite the dim industrial lighting and the presence of light surface dust, the valve maintained excellent sealing integrity and operational stability. Surrounding safety features, such as anti-slip flooring and yellow warning lights, reflect the high safety standards of Felo’s industrial installations.
