HDS600 Series Nitrogen Seal Device

Categroy: Control Valve

HDS600 series nitrogen sealing device are a type of self-operated regulating valve developed by our company. It is a pressure regulating device no needs of external energy and can be used for air seal in various of storage tanks such as oil products, chemicals and liquid. The device is composed of two parts: nitrogen supply regulating valve and nitrogen release regulating valve( sometimes replaced by breathing valve). The nitrogen supply regulating valve has the characteristics of wide pressure reducing ratio, large flow rate and low set point of pressure. The nitrogen release valve has the characteristics of low set point of pressure, sensitive action and high accuracy of regulation. Normally, the nitrogen supply regulating valve shall be used together with the nitrogen relaease regulating valve to form a complete nitrogen seal regulating system, and can also be ordered seperately according to the user's requirements.
