Multi-Offset Butterfly Valves
Case Material: Alloy Steel
Material of the locking element: alloy steel Stem material: stainless steel
Nominal diameter (DN, mm): 50 ... 1600
Working pressure, MPa: 0.1 ... 1.6
Processing medium: abrasive media, aggressive media, industrial gases, sea water
Butterfly valves are designed to distribute flows in the oil and gas, cryogenic, chemical and energy industry, as well as in fire extinguishing and water and heat supply systems.
As compared to double-offset butterfly valves, three- and four-offset ones have a metal-to-metal increased wear resistance seal, which allows the valves to be used in aggressive environments with a wide range of operating temperatures and pressures. In addition, the butterfly valves have a high flow coefficient and a sufficiently low torque required to control the valves.
