1. The valve is mainly composed of valve body, valve disc, valve cover, valve stem, indicator assembly and hand wheel.
2. Principle: rotate the hand wheel to make the valve stem rotate, so as to drive the valve disc to rise or fall, and change the spacing between the valve disc and the valve seat. The spacing can be read from the indicator ring and scale on the valve stem, so as to realize the adjustment of medium flow
1. The structure is reasonable and compact, the volume is small, the appearance of the valve body is barrel or streamline, and the shape is beautiful.
2. Small opening and closing torque and safe and reliable sealing.
1. The product shall be stored in a dry warehouse and shall not be stored in the open air.
2. Keep it for a long time and maintain it regularly.
