Self Operated Nitrogen Supply Control Valve

Nitrogen seal control valve has two kinds of Nitrogen supply regulation and nitrogen release regulation, which can depend on the pressure change of the regulated medium itself to achieve the purpose of automatic regulation and stable pressure. It is mainly used to keep the container at the top of the shielding gas (usually nitrogen) pressure constant, so as to avoid direct contact with the air container material, prevent evaporation materials, oxidation, and the safety of the vessel.

Self Operated Pressure Control Valve Boiler Steam

Self-operated pressure control valve consists of a control valve, an actuator and a spring that sets the pressure. Suitable for non-corrosive liquids, gases and vapours, in front of valves in the system piping (when the pre-valve pressure rises, the control valve opens) or after the valve (when the post-valve pressure rises, the control valve closes) pressure control.

Self Operated Micro Pressure Differential Nitrogen Supply and Sealing Regulating Valve

Self-operated micro-pressure differential nitrogen supply and sealing regulating valve is mainly characterized by the use of nitrogen closed design, can effectively prevent nitrogen leakage and pollution of the environment. At the same time, the valve adopts a micro-differential pressure controller, which can realize precise nitrogen flow control and meet the requirements of different nitrogen protection systems.

Self Operated Single Double Seat Sleeve Pressure Temperature Flow Regulating Valve

The main characteristic of self-operated single double seat sleeve pressure temperature control flow regulating valve is the use of double seat design, both sides of the spool have sealing surface, so that the valve sealing better, lower leakage rate. At the same time, the sleeve of the valve is designed with a single seat, which makes the adjustment range of the valve larger and higher adjustment precision. In addition, the valve also has pressure and temperature control function, can be adjusted as required, making valve use more flexible.

Self Operated Carbon Steel Pressure Regulating Valve

Self-operated carbon steel pressure regulating valve is a kind of can be widely used in the field of industrial regulation valve, its main function is to control the flow and pressure of the medium, to achieve the stability of the pressure system. The working principle of self-reliant carbon steel pressure regulating valve is to use the pressure of the medium acting on the spool and spring, making the spool move up or down, so as to change the flow and pressure of the medium, to achieve the stable regulation of the pressure system.

Double Diaphragm Fluorine Lined Self Operated Nitrogen Seal Regulating valve

Double diaphragm fluorine lined self-operated nitrogen seal regulator is a valve that can be used in high temperature, high pressure, corrosion and other harsh conditions. It is upgraded and improved on the basis of the ordinary self-reliant nitrogen seal regulating valve, using double diaphragm structure and fluorine plastic lining material, to achieve higher sealing, better corrosion resistance and longer service life.

Nitrogen Discharge Self Operated Micro Pressure Device Control Valve

Nitrogen relief self-actuated micro-pressure device regulating valve is a valve for pressure control, suitable for pressure control in high-pressure gas systems. The valve uses a self-reliant micropressure regulator to control system pressure by adjusting spring force and spool position.

Self Operated Micro Pressure Control Valve

Self-operated micro-pressure control valve can be widely used in the medium pressure is not greater than 1.4MPa, the operating temperature is not greater than 120℃(or 150℃), pressure regulation range in 0.14-7.2KPa non-corrosive gas or air medium after the valve pressure (mm water column level), widely used in a variety of oil products, chemicals, liquid storage tank gas seal pressure regulation device.

Self Operated Flow Temperature Control Valve

The working principle of self-operated flow temperature control valve is based on the law of thermodynamics, and the opening degree of the valve is controlled by the temperature and pressure of the fluid. When the temperature or pressure of the fluid changes, the position of the valve will be automatically adjusted to keep the flow and temperature of the fluid within the set range.
