MVC Industrial Valves
In order to efficiently serve our customers, we
have opened MVC in USA. All this infrastructure
enables us to serve the market of North America,
Central America, South America, Europe and
Africa
It is fully committed to promoting technological
development in the fields of low temperature,
high temperature, high pressure air sealing, low
torque and minimal leakage.
In 2012, we established factory in China. With Production&Management
Quality System Team
extensive application experience and compre-
hensive capabilities, we provide tailor-made
solutions for your valve automation needs.
MVC's management team adheres to strict policies ensuring
that no defects occur in the valves used for industrial services.
To maintain this discipline, we enforce internal regulations and
a robust working process system. Third parties and customers
are regularly invited to audit and approve our system.
MVC holds ISO9001, API6D, CE, TS, and other key certifica-
tions. All raw materials undergo re-testing for properties and
mechanical performance upon arrival at our factory to ensure
they meet machining standards. Non-destructive testing (NDE),
including UT, MT, PT, and RT, is conducted by our quality
control department during or before machining.
Every valve undergoes shell and sealing hydraulic tests, as well
as air sealing tests. For valves used in special applications,
additional tests such as fugitive emission, high/low temperature
cycling, life, fire safety, cryogenic, and cleanliness tests after
degreasing are available upon client request.

Full port ball valve design minimizes pressure loss and increases flow capacity
to reduce energy and pumping costs. The integration of ball and stem prevent
stem blowout and improve operating personnel safety. Compact design
reduce the medium retention. In addition, the special molding process assure
perfect sealing surface, ball valve can reach to zero leakage.
