Are butterfly valves with a maintenance compartment considered top-mounted butterfly valves?

Question: 1. Are butterfly valves with a maintenance compartment considered top-mounted butterfly valves? 2. What material is generally used for the sealing ring installed on the butterfly valve disc? Our company uses 304 thin sheet metal combined with graphite sheets layered together; we were informed that if it were a purely forged component, the valve would experience internal leakage.

Butterfly valves with maintenance access holes are not top-mounted butterfly valves; do not confuse them!

The material of the sealing ring depends on the manufacturer and the specific application; generally, SS316 is used for imported products
