Butterfly valves with stainless steel disk
Butterfly valves with a stainless steel disk are used in work with aggressive medium that require increased wear resistance from the equipment. They are used in the oil and gas industry, the chemical industry, and the housing and utilities sector. For the manufacture of disks, CF8 stainless steel (AISI 304) and molybdenum-containing stainless steel (CF8M / AISI 316) are most often used. Such valves ensure сlass A tightness, extend the service life of the pipeline and work without leaks under the design conditions specified in the documentation. Depending on the operating conditions of a butterfly valve, the disks can be made of special grades of steel that are more resistant to aggressive medium, abrasives, etc.
Butterfly valves with a stainless steel disk are among the most common, especially in the series PA 300, PA 600.
Advantages of stainless steel butterfly valves
Stainless steel gives the armature the following advantages:
- the ability to work at high temperatures up to +600°C, and low-up to -55°C;
- the possibility of operation at high pressure;
- the high strength and tightness of the valve makes it possible to work with a variety of media-from gas in the refinery to viscous oil and resin.
Steel grades CF8 and CF8M are resistant to alkalis, acids, do not break down under the influence of high temperatures.
A stainless steel butterfly valve with a stainless steel disk is mainly installed by the wafer connection, but there are also options for installation by the flanges and welding.
