Product overview

Self-operated pressure control valve with a controller (nitrogen seal device) is mainly used for constant nitrogen pressure control at the top of the storage tank. Self-operated nitrogen seal valve is a kind of non-external energy, using the spring as the power core and the pressure of the medium itself to control the position change of the valve core, so as to achieve the purpose of automatic regulation and stable pressure, so as to protect the materials in the tank from nitriding and the safety of the storage tank. The valve is composed of ZZYVP quick relief valve and ZZV self-operated micro-pressure regulating valve. The quick release valve is composed of a pressure controller and a ZMQ-16K single-seat shut-off valve.
