Wafer butterfly valve

Offering resilience and cohesion to pipelines, wafer butterfly valves are designed with a reliable valve seat which allows for the flange to be easily connected to the valve. Meeting ANSI/API, BS, DIN, and JIS requirements, our wafer-style butterfly valves are made with quality metal material that enables valves of this type to withstand harsh conditions while maintaining overall cleanliness.
