Buy Triple Offset Butterfly Valve which Can be Customized From Our Factory in China
1.Introduction of Triple Offset Butterfly Valve
Triple offset butterfly valve is a valve in which the shaft center of the valve stem deviates from the center of the disc and the center of the body at the same time, and the rotation axis of the valve seat has a certain angle with the axis of the valve body channel. The Triple offset butterfly valve produced by Milestone Valve Co. Ltd. is widely used in metallurgy, electric power, petrochemical, and water supply and drainage industrial pipelines with a medium temperature of 425℃ or less. The materials are divided into: cast iron, cast steel, and stainless steel.

3.Features of Triple Offset Butterfly Valve
1) Triple offset butterfly valve integrates adjustment and cutting in one, with strong controllability. The Triple offset butterfly valve is designed with a double safety structure. In order to prevent the deformation of the butterfly plate, the misalignment of the valve stem, and the sealing surface occlusion caused by the influence of fluid pressure and temperature, two independent stoppers are installed on the upper and lower sides of the butterfly plate. Push ring, thus ensuring the normal operation of the valve under any working conditions;
2) Triple offset butterfly valve has no dead zone design and small opening torque.
The Triple offset butterfly valve achieves that the butterfly plate does not scratch the valve seat when the valve is opened and closed, and the torque of the valve stem is directly transmitted to the sealing surface through the butterfly plate, and the opening torque is small, thereby eliminating the common jumping phenomenon when opening the valve.
3) Triple offset butterfly valve has zero leakage, high temperature and high pressure resistance.
The biggest feature of the Triple offset butterfly valve is that it fundamentally changes the sealing structure. It is a torsion seal, which completely relies on the contact surface pressure of the valve seat to achieve the sealing effect, so that the Triple offset butterfly valve can achieve true zero leakage. At the same time, the structural characteristics of the metal seat and face seal make the Triple offset butterfly valve have high temperature and high pressure resistance.
