Bellows sealed globe valve, and its key components - metal bellows, the lower end of stem components with the introduction of automatic welding roll, roll the top and automatic welding, in the fluid medium and the atmosphere to form a metal barrier to ensure that the valve under zero leakage. Valve with the valve sealing surface through precision grinding, assembly, after 100% completion of pressure test, all to achieve zero leakage. As a supplement, in sealed bellows fill the above letter is still preserved, but also increased the reliability and security. High-pressure metal bellows valves are multi-storey structure Hydroforming can ensure to the maximum 10000 times under the pressure of the whole trip on / off life.
The use of advantages:
1, a double seal design (bellows + fill) if the bellows failure, will prevent the leakage of valve stem packing and seal in accordance with international standards.
2, security, environmental protection, there is no fluid loss, reduce energy loss and improve plant safety.
3, long service life, reduce maintenance and lower operating costs.
4, the rugged design of bellows seal globe valve to ensure zero stem leakage, to provide the conditions for maintenance.
The use of:
Applicable to heat-conducting oil, toxic, flammable, permeability, and pollute the environment with radioactive fluid medium for the shut-off valve control on the road, can also be used for regulation, is to create quality products without leakage of the plant. All of the valve castings precision casting.
