Product Features

The valve spoolassembly of the valve is composed of wedge-shaped blocks, left and right blocksand left and right gates. The large-gap movable connection structure betweenthe parts can be self-aligned, self-disengaged and self-adjusted.

Mohs wedge angledesign, wedge surface can be hardened, no self-locking tendency, low frictionalresistance, flexible opening and closing.

The internalmetal is designed to meet the requirements of high and low temperature.

Fully-guidedstroke design for full valve installation.

The shutter has a self-cleaningfunction. When the valve is opened and closed, the ram can rotate naturallythrough the flow of the medium in the pipe, so that it can be cleaned by itselfto increase the service life of the valve.
