Triple Eccentric Electric Butterfly valve, Metal Sealing Butterfly Valves, Triple Offset Butterfly Valve
Design Feature
Medium can flow through the body directly for little resistance and high flow capacity.
The body and upper cover could be made of carbon steel,austenitic stainless steel or special alloy material.
The sulfur-free flexible v-graphite is heat resisting,we shall ensure the service life of packing is long-term without maintenance by increasing pre-pressure on spring gasket.
The self-sealing packing structure is tested 100,000 times (full travel) to ensure zero leakage and constant friction.When the stem moves at low friction state,we can get the long-term steady precision of control valve .
The seat adopts multi-level structure, the sealing surface is composed of metal and special non-metal materials to ensure zero leakage.
The shaft center deviates from the valve center bi-directionally. The asymmetric design sealing surface allows the disc to revolve in 0-90° freely.
