This Beaver butterfly valve series has a resilient elastomer seat that protects the valve body from coming into contact with the media. The rounded disc closes with zero leakage at full pressure rating in either direction.

This lightweight and compact valve rated to 10 bar requires low-torque operation. It comes in either a wafer or lugged body, both of which are suitable for isolation. The lugged valve can be used for end-of-line services.
