Stainless steel butterfly valves
Stainless steel butterfly valves, also known as stainless steel butterfly valves, are essential components of many industrial flow control systems. These valves are designed for versatile and reliable use in pipework systems and can be installed between flanges (flanged and wafer bodies) to PN10/16/150lbs standards. The head flange complies with ISO 5211, which ensures easy automation and compatibility with various actuator systems. Thanks to their tight-closing, centre-mounted design, these butterfly valves offer maximum tightness and efficiency. The body and disc are made of stainless steel CF8M (1.4408), which guarantees excellent corrosion resistance and durability in demanding environments. The shaft is made of AISI 420 stainless steel, which provides additional strength.
With a maximum pressure rating of 16 bar and an EPDM seat ring that covers temperature ranges from -10°C to +120°C, these stainless steel butterfly valves are ideal for use in a wide range of applications. They are ideal for use in water supply systems, chemical processes, food and beverage production and the oil and gas industry.
Several options are available for actuation, including hand lever, gearbox, pneumatic and electric actuators. This flexibility makes the stainless steel butterfly valves an ideal choice for companies that require reliable, high-performance valves in their systems.

FAQ: Stainless steel butterfly valves
A stainless steel butterfly valve is a valve unit in which the body and the valve construction are made of stainless steel. This material offers high strength, corrosion resistance and is suitable for a wide range of industrial applications.
Stainless steel butterfly valves are widely used in industrial applications, particularly in chemical plants, petrochemicals, the food industry, water and wastewater technology and other environments that require high resistance to corrosion.
The main advantages include excellent resistance to corrosion caused by chemical substances, high temperatures and pressure fluctuations. Stainless steel butterfly valves are durable, low-maintenance and therefore well suited for demanding industrial applications.
Stainless steel butterfly valves are often made from stainless steel alloys such as AISI 304, AISI 316 or other special alloys which, depending on the application, offer the desired properties such as resistance to acids, alkalis or salt water.
Sealing materials for stainless steel butterfly valves vary depending on requirements and can include materials such as EPDM, Viton, PTFE or other specialised elastomers that offer high temperature, chemical resistance and sealing properties.
When selecting a stainless steel butterfly valve, factors such as the type of media, operating temperatures, pressure conditions, size of the valve opening and specific requirements for chemical resistance and operational reliability are decisive.
