All Metal Valve

Conventional valve uses Viton at the dynamic sealing area which prevents the valve from high temperature exposure. All Metal Valve uses oxygen-free copper gasket as dynamic seal to press against a conical knife edge on the opposing part, thus forming an all metal seal.

Copper gasket has a life of few hundred uses. Replacement is easily done by a screw driver.

Feature and Notice:

2. The poppet seal gasket is easily replaced by a screw driver; it can be
removed through the side port.
