ABSTRACT:
Improvements in devices for metering the flow of molten material such as glass include a catenary support structure, internal passageways in the bulbous valve body for directing molten material to the downstream side of the support arm or arms, and electrical isolation of the valve components from each other to recude electrolytic corrosion. An advantage of the invention is that use of precious metals such as platinum is avoided.
