Nitrogen Blanketing Valve (Supply)& Nitrogen Vent Valve (Relief)
Description
* The Nitrogen Seal Valve isan automatic pressure control device used forclosedcontainerssuchasdrystoragetanksandreactors. It maintains a slightly positive internal pressure by injecting nitrogengas,effectivelypreventingmaterial oxidation,moisture absorption,volatilization,orexplosionrisks causedbycontactwith air.
\bullet Widely used in industries such as petrochemicals, pharmaceuticals，food processing，and fine chemicals，the nitrogen seal valve is a key component in ensuring storage safety and product quality.The nitrogenseal system typically consists ofa nitrogen supply valve (fillingvalve)and a nitrogen relief valve (exhaustvalve),or can be integrated intoa single unit for“filling and exhausting"with intelligent control.
Key Features: The nitrogen release device consists of a micro-pressure regulating valve with internal feedback for precise pressure control.
The pressure sensing diaphragm has a large effective area,small spring stiffness,and quick response,ensuring stable operation of the system.
The nitrogen seal valve has a set nitrogen pressure range,and the pressure is precisely controlled by the nitrogen sealing valve device.
\bullet The nitrogen supply system is controlled by pilot control,with a ressure drop ratio up to 1oo:1,offering excellent pressure reduction and high control accuracy.
