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.
- Triple offset with metal seat design.
