The main feature is tight casting (resin sand), which makes the surface of the regulating valve smooth and even, reduces the sand hole rate to 0, and ensures the service life of the all metal linked valve seat meets the national standard GB/911.3-2000 for steel pipe flanges? The valve core with a percentage flow design determined through hundreds of tests in accordance with the special equipment manufacturing license issued by the Provincial Quality and Technical Supervision Bureau has a more precise regulating performance. The pressure balanced structure of the valve core reduces the requirements for execution force and saves costs. The pressure difference self balancing structure of the valve core enables the regulating valve to have higher shut-off ability, allowing the valve to operate freely under high pressure difference. The variety is complete and can meet the different industry requirements of valves in multiple fields such as HVAC, urban heating, food processing, and industrial production.
