District Heating Butterfly Valve

Tipvalve District HeatingTriple Offset Butterfly Valve design is recommended for district heating and district cooling applications requiring reliable zero-leakage, bi-directional quick shut-off in harsh conditions of critical processes, steam isolation, and temperature extremes within co-generation (combined heat& power) systems, available in carbon and stainless steel the valves are designed for durability to provide low life time costs.
Tipvalve largest butterfly valves are 1400mm nominal bore! butterfly valves can be specified with laminated seal(stainless steel&graphite seal) or all-metal seal to make better sealing.
