·Long neck valve cover design: Extend the neck of the valve cover to reduce the transmission of cold to the operating mechanism and prevent the packing from freezing. The neck length is calculated and determined based on factors such as the thermal conductivity and heat dissipation coefficient of the material, ensuring that the temperature at the bottom of the packing box remains above 0 ℃.
·Anti abnormal pressure rise structure: A pressure relief hole is installed on the inlet side of the gate plate. When the pressure in the valve chamber increases, gas can be discharged through the small hole to prevent the gate plate from tightly pressing the valve seat and causing it to fail to open.

Our company has developed a variety of series of Angle control valves. They feature a compact valve body structure, low pressure drop loss, large flow rate, unobstructed flow channel with low resistance within the adjustable range, and high accuracy of the flow curve. It is particularly suitable for regulating high-viscosity fluids containing suspended solids and granular materials, which can prevent coking, adhesion, clogging and other phenomena, and is convenient for self-cleaning and cleaning. The control valve is equipped with the RSMF type multi-spring pneumatic diaphragm actuator, which features a simple and firm structure, large output force and long service life.
Oxygen Globe Valve are often used in physical and chemical experiments with gases such as oxygen, nitrogen, hydrogen, argon, etc. These gases are usually stored in dedicated high-pressure gases. When in use, the gas pressure is reduced to the required range for the experiment through a pressure reducing valve, and then finely adjusted through other control valves to input the gas into the system. The oxygen shut-off valve is a forced sealing valve, so when the valve is closed, pressure must be applied to the valve disc to force the sealing surface not to leak.
CW700 Series Bellows Seal Control Valves are divided into three major series: CSW701/CW701/CW702/CLW702 type bellows-sealed single-seat regulating valves and bellows-sealed cage-type regulating valves, as well as low-leakage bellows-sealed cage-type regulating valves. The bellows-sealed single-seat regulating valve is a regulating valve with top guide structure. The bellows-sealed cage-type regulating valve is a regulating valve with pressure balance. The valve body has an S-flow channel type passage, with small pressure drop loss, large flow rate, wide adjustable range and high flow characteristic accuracy. The low-leakage bellows-sealed cage-type regulating valve not only has the advantages of cage-type regulating valves, but also has a sealing ring between the valve core and the valve cage, reducing the leakage. The full series of upper valve covers adopt bellows-sealed structure, which can completely eliminate the possibility of medium leakage from the valve stem movement gap to the outside. When equipped with the RSMF series actuators, it has a compact structure, large output force and long service life. Therefore, it is widely used in automatic control systems of highly toxic, strongly corrosive, radioactive and rare and precious media. *CSW701Bellows Seal small-Port single-seat control valve *CW701 Bellows Seal single-seat control valve *CW702 Bellows Seal caged globe control valve *CLW702 Bellows Seal Low-leakage bellows caged globe control valve
