Application£º Our HTNJ series Pressure Relif Valve (Pressure Relief Valve with Jackt) is applied for the equipment of polyster, ethlyne, heavy oil refinery, urea and fertilize in the industry of Petrochemical, Chemical where request the heat preservation location. The valve body inlet and outlet flange is heat preserved which supplies a better effect. The construction of ballanced bellows protects set pressure from being affected by variable back pressure and the parts in bonnet, such as spring from being corroded.
