During the opening and closing process, the friction between the valve petals and the cover surface is small and wear-resistant. The itinerary height
is relatively small. The action is sensitive and the sealing performance is good; The overall structure, simple and compact, beautiful shape. Long
service life and high reliability.
Application Scenario: The deeper valve is generally used on the pipelines that are not strict with the flow resistance on the pipeline, that is, the place where the pressure loss is not large. For example, a high-temperature and high pressure working medium, toxic and harmful risk liquids require
closure to ensure long-term sealing and leakage. Under normal circumstances, the requirements for use requirements are reliable. Such as the
application of power industry, petroleum refining, petrochemical industry, marine oil, tap water engineering in urban construction, chemical industry
and other fields.

Special type control valves are customized valve products designed by our company for complex working conditions (such as high temperature, high pressure, strong corrosion, high precision, and low-temperature control, etc.). They possess the ability to precisely regulate flow and pressure, and can meet the stringent requirements in industrial processes.
The cryogenic butterfly body can be provided in twostructural forms, namely flange connection and butt.welding connection (both with inspection ports). The body with inspection ports can replace the valveinternals online, making maintenance work extremelysimple, which is conducive to the rational use ofresourcesand saving maintenance costs.The extended valve cover + drip tray design ensures thatthe temperature at the stuffing box is above zero degrees!so that the connection between the stuffing and the stemwill not freeze and lock.
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.
