The PTFE Butterfly Valve features a non-toxic PTFE seal that also partially covers the outer body of the valve for perfect sealing with counter flanges. This makes them ideal for use in highly corrosive environments and higher service temperatures where traditional materials fail. J&J Electric Actuators are made with a durable polyamide housing that is resistant to corrosion. Our actuators also have ingress protection of IP67, meaning they are completely weatherproof and can be used in indoor or outdoor settings.
