The opening and closing parts of the national standard globe valve is a cylindrical valve flap, the sealing surface is flat or conical, the valve flap along the center line of the fluid for straight-line movement. National standard globe valve is only applicable to full open and full closed, generally not used to regulate the flow, customized to allow for regulation and throttling. The products are suitable for petroleum, chemical, pharmaceutical, chemical fertilizer, electric power industry and other conditions of the pipeline, cut off or connect the medium. Cut-off valve applicable media: water, oil, steam, acidic media. Operation mode: manual, gear drive, electric, pneumatic and so on.

1.National standard globe valve design and manufacture according to national standards GB/T12235, reasonable structure, reliable sealing, excellent performance, beautiful modeling.

2. Valve flap, valve seat sealing surface with iron-based alloy surfacing or Stellite (stellite) cobalt-based cemented carbide surfacing and become wear-resistant, high-temperature resistant, corrosion-resistant, anti-scratch performance, long service life.

3. The valve stem is tempered and surface nitriding treatment, has good corrosion resistance and anti-scratch.

4. Various piping flange standards and flange sealing surface forms can be adopted to meet various engineering needs and user requirements.

5. The inverted seal adopts threaded connection sealing seat or body surfacing welding austenitic stainless steel and become, reliable sealing, packing and day-to-day replacement can be carried out conveniently and quickly without affecting the operation of the system without stopping.
