Self-Operated Nitrogen Sealing Control Valve-ZZYVP-16
ZZYVP type commander operates the self-operated pressure regulating valve (nitrogen sealing valve), which is an energy-saving pressure regulating valve that can automatically adjust and stabilize the pressure behind the valve to a set value by using the pressure change of the regulated medium itself without external energy. The pressure setting of the valve is realized on the commander, which is convenient and fast, and the pressure setting value can be adjusted at will during operation; The control precision is high, which is twice as high as that of ordinary directly operated self-operated pressure regulating valve, and is suitable for occasions with high control precision requirements. It is widely used in chemical, petroleum, metallurgy, electric power, textile and other industrial sectors as automatic regulation of production process.
Model: Self-Operated Nitrogen Sealing Control Valve
Size Range: 1/2”~12′
Pressure Range:1.6~6.4
Material: WCB, Stainless Steel 304/306
Description
Self operated nitrogen sealing valve is mainly used for constant control of nitrogen pressure at the top of the storage tank to protect the materials inside the tank from being nitrided and ensure the safetyof the storage tank, the pressure regulating valve with a controller consists of two main parts: A quick release valve and a self operated micro pressure regulating valve. The quick release valve consists of a pressure controller and a single seat shut-off valve.
Working principle: When the pressure inside the storage tank rises to the set pressure the ouick release valve ouickly opens to release excess pressure inside the tank. When the pressure inside the storage tank decreases, the micro pressure regulating yai veopens and fils the tank with nitrogen gas dueto the fact that the micro pressure regulating vaive must re used at a pressur ebelow o impa and the on-site pressure is high.A pressure regulating valve must be installed to reduce the pressure to below o impabeforeit can be used. The nominal pressure is 0.Impa,and the pressure can be set in stages,ranging from o.Skpa to below 66kpa.The mediumtem perature iss 80 ”c.
