Bolted Bonnet API Globe Valve
Products Design Features
Globe valve are used to cut or connect the pipe media under nominal pressure betweenPN1.6-160MPa(Class150-2500) working temperaturess600C.in oil industry chemical industry pharmaceuticals fertilizer and power industry.
The main structure features include:
1、Rational structure.reliable sealing excellent performance pretty appearance
2、Co-radix alloy welded sealing surface anti-wearing erosion-proof abrasion-proof and longer use life.
3、The surface and the adjusting media of the valve shaft are nitrogenized so that it is erosion and abrasion resistant.
4、PN>25.0MPa(Class1500).the middle cavity use a self-tightening sealing structure to have the sealing performance reinforced
along with the pressure rise so as to ensure the sealing performance.
5、There is no backward sealing structure in the valve, so the sealing id reliable.
6、The material of the filling and the flange size can be chosen and matched according to the applications and the requirements of the use's. That can satisfies all kinds of working requirements.

Quality Control
Continuous improvement and zero defects is BVMC’s eternal quality policy and objective. Based on international and domestic industrial standards and customer requirements, we set up higher internal quality assurance standards to implement comprehensive and full quality management. BVMC has a world-class testing center that enables us to independently complete all tests by ourselves, from product prototype tests to final inspection. The inspection and tests include:
• NDE (RT,PT,MT,UT )
• Chemical analysis test
• Physical test (impact test, Tensile test, Bending test)
• Fire test
• Cryogenic test
• High temperature test
• Vacuum test
• Fugitive emission test
• Pressure test(Shell test, Hydraulic test, Air test )
• Visual inspect
• Dimensional inspect
• Painting test
From raw materials to finished products BVMC effectively controls each process. In addition, BVMC actively employs 6 Sigma within the whole company to implement our “zero defects” program. Through advanced statistical analysis we continue to improve process control and management capability.
