● A single elastic valve seat sealing structure achieves dynamic sealing through system pressure, and is durable;
● It can maintain reliable sealing without the need to use additional sealing rings or metal components;
● It can operate a bidirectional leak-free seal;
● The lip-edge sealing design compensates for temperature and pressure changes during use;
● The double eccentric structure ensures no contact between the valve seat and the disc during opening and closing, eliminating wear at both the upper and lower ends of the valve seat during frequent opening, reducing the operating torque, and lowering the requirements for the operating machinery.
● There is a fly prevention step at the top of the shaft, which prevents the upper part of the shaft from moving out of the valve cover in case of an accident.
● Maintenance is convenient. Just remove the pressure plate to replace the valve seat, without the need to disassemble the disc and the shaft.
● It combines flow interruption and control, featuring excellent control characteristics; the flow characteristic curve is in a geometric ratio change; the adjustment range is wide; even when used for control, it can still achieve a tight seal;

The C700 Series Low-Noise Control Valve is divided into the CN702 and CDN702 series, mainly designed to reduce the noise of compressible fluids. To adapt to the throttling, diffusion and expansion of gases, the valve core adopts a pressure-balanced structure, and the sleeve is equipped with many symmetrical small holes to reduce pressure drop. The fluid passage is in an S-shaped streamline, and a deflector wing is also provided to improve the smooth flow of the fluid around the sleeve. Therefore, the control valve has low pressure drop loss, large flow rate, low noise and less cavitation corrosion. The control valve is equipped with the RSMF series multi-spring pneumatic diaphragm actuator, which has a simple and compact structure, stronger stability, large output force and long service life.
The Power Plant Gate Valve is mainly suitable for the pipelines of various systems of thermal power station, cutting or connecting the pipeline medium. Compared with other valve products, the Power Plant Gate Valve is characterized by high temperature and high pressure. It is counted as a unique and closely sealed structure. The higher the pressure, the more reliable the sealing performance. Due to the characteristics of performance and technical characteristics and working conditions, the product has also formed the characteristics of other products that cannot be replaced. This type of valve should generally be installed horizontally in the pipeline. The Power Plant Gate Valve has the design characteristics of ordinary wedge-type gate valves. The valve body has a guide mechanism to prevent rotation when the gate is turned on or closed to ensure that the seal of the gate on the valve seat is correspondingly accurate. At the same time, the wedge valve does not rub with the valve seat before turning off, thereby reducing the wear of the cover and effectively extending the service life of the valve.
The globe valve is mainly composed of valve body, valve cover, valve disc and valve stem. The handwheel applies a certain torque at the upper end of the valve stem. The valve stem is passed to the valve petals through the valve stem, so that it moves up and down along the valve stem axis to achieve fully turned on or fully closed movements. The force applied by the handwheel acts on the disc to hold it against the seat to seal. The single disc globe valve is designed to enter the medium by the valve disc sealing surface below, the medium force is opposite to the direction of valve closing, so the valve closing torque is large, so the single disc globe valve is mainly used in low pressure or small diameter pipelines. At the same time, the globe valve does not rub with the valve seat before the valve is closed, thereby reducing the wear of the cover surface and effectively extending the service life of the valve.
