Eccentric Rotary Control Valve

Our eccentric rotary valve has a novel structure. Its body is similar to a cylinder. An eccentricity is designed between the spherical center of the spool and the rotation center of the shaft. When the shaft drives the spool to rotate, the spool spherical surface does an eccentric rotation relative to the body center. The trajectory is a cam-shaped curve. When the rotary valve is closed, the flexible arm of the spool is elastically deformed, making the spherical center of the spool closely fit the seat and realizing reliable sealing. Therefore, this product is also named cam deflection valve.

This product has a large rated flow coefficient and the two directions of flows have high dynamic reliability. Our product is compact in structure and light in weight, which is easy to install. It also features good sealing performance and wide applicable temperature range. With a simple flow path, our product is suitable for high-viscosity, particulate media.

Flanges are in accordance with the ANSI B 16.5 standard.
