The stainless steel butterfly valve is ideal for all industrial applications

stainless steel butterfly valve [stainless steel butterfly valve]

Omega Valves has different types of stainless steel butterfly valve available to meet your requirements.

Butterfly valves are used for isolating or controlling the flow of fluids. The butterfly valve can be operated either manually by hand (locally) or automatically by an actuator (remotely). Most butterfly valve types are bi-directional and can be rotated in either direction.

Benefits of stainless steel butterfly valve

The stainless steel butterfly valve is the ideal option for industrial applications.

Feature Benefit
Corrosion resistance Stainless steel is highly resistant to corrosion, stain, rust and environmental conditions. Stainless steel eliminates the need for a protective layer of coating or paint.
Extreme temperature Stainless steel can withstand extreme temperatures ranging from -196⁰c to +425⁰c.

Stainless steel is the preferred choice for cosmetic, pharmaceutical and food manufacturing industries. The material is highly resistant to corrosion and rusting, and supports the CIP (clean in process) procedure to prevent germ accumulations.

Stainless steel hygienic butterfly valves are highly polished to avoid build-up of deposits on the metal surface, and are designed to avoid ‘dead areas’.


The 2 piece and 3 piece stainless steel butterfly valves are long lasting and easily maintainable.

Spare parts for the valves are readily available and can be replaced effortlessly to maintain a continuous work flow. These valves are versatile in nature and can be used in another section of the plant for different services. 

Weight The high-performance butterfly valves are lighter and more compact in design, compared to the ball valves with the same pressure rating.

Benefits of stainless steel double and triple offset butterfly valves

Feature Benefit
The ‘cam action’ and ‘right angled conical sealing’ design  The design ensures that the metal sealing components make contact. The result is an accurate sealing operation and a longer shelf life.
Low valve torque Small actuators can be used, which lowers the cost of automation.
Minimal maintenance Replaceable seat and seal components provide minimal maintenance.
Low fugitive emissions Low fugitive emissions due to the quarter turn technology.
Metal to metal sealing High pressure and temperature applications are possible with metal to metal sealing.
