The nitrogen supply valve (nitrogen supply device) does not require external energy and uses the energy of the regulated medium itself as a power source to automatically control the flow rate of the valve medium and maintain a constant pressure behind the valve as an air seal device. It has been widely used in gas and nitrogen sealing systems such as storage tanks, thermal oil tanks, and ultrapure water.
