Triple Offset Butterfly Valve

Product Use

Triple Offset Butterfly Valve Series are designed by Tri-Eccentric Principle, having flexible seat and laminated seat structure, without mechanical wear during opening and closing process. The valves are mainly used for isolating, regulating or connecting flow in Oil, Chemical, Metallurgy, Electric Power, Food, Medicine, Water Supply and Drainage, Gas Transportation etc. pipes of different medium.

Structure Characteristic

This kind of butterfly valve is new and superior product, which introduced technology from abroad, and combine domestic and overseas user's requirements and experience accumulation from production.

1. It adopt three-dimension eccentric configuration

2. Particular configuration, operation skillful, labor-saving, convenient, and long service life.

3. High temperature resistant, antisepsis, wearable of three-dimension eccentricity.

The Triple Offset Geometry

• The first eccentric, shaft deviated from the centerline of sealing face.
• The second eccentric, Shaft deviated from the centerline of pipe and valve.
• The third eccentric, the distinctive included angle between oblique taper angle of eccentric seat and centerline of pipe, thus making the seat completely disengaged from the sealing ring during the whole process of open and close. This structure not only uses cam effect, but also eliminates the possibility of abrasion and leakage.

Main Technology Parameter

• Nominal Diameter: DN 50–3000 mm
• Applicable Medium: Air, gas, water, steam, oil, acid corrosion media, etc.
• Applicable Temperature:
• Carbon Steel: -29°C ~ 425°C

Manufacturing Process

Applications

The triple offset butterfly valve is typically used for fluid control under harsh conditions such as high temperature, high pressure, and high viscosity. Due to its excellent sealing performance, it is often employed for flow regulation, preventing backflow, and controlling the flow of liquids and gases in industries such as chemical processes, oil and gas extraction. Its working principle is based on a unique biasing structure, which achieves precise control of the fluid by changing the contact position and area between the butterfly plate and the valve seat. Therefore, it performs exceptionally well in the control of high-temperature, high-pressure, and high-viscosity fluids and is an indispensable key component in fluid control systems.
