Butterfly Valves
What are Butterfly Valves?

Butterfly Valves are rotary motion valves used to regulate and isolate fluid flow within dairy and sanitary processing systems. Featuring a disc that rotates 90° to open or close the flow path, these valves are known for their compact design, quick operation, and low-pressure drop. They are ideal for handling milk, cream, whey, and cleaning agents in hygienic environments.
Asiad Steel Industries is a trusted manufacturer and exporter of premium-grade Butterfly Valves engineered specifically for dairy and food-grade applications, offering Tri-Clamp, SMS, and DIN end connections.

Do you have questions?
Can butterfly valves handle cleaning fluids?
Yes. They are designed to tolerate caustic CIP/SIP fluids and maintain sanitary integrity.
What type of actuator can be used?
We offer both pneumatic and electric actuators, depending on your process automation needs.
Are seals replaceable?
Absolutely. We provide FDA-approved seal kits for easy maintenance and replacement.
Can I get butterfly valves in SMS and DIN connections?
Yes. We manufacture valves in all standard dairy fittings including SMS, DIN, IDF, and Clamp.
