UTMOST is a triple eccentric butterfly valve factory in China. This valve uses a triple-offset sealing geometry and torque-seated closure for industrial isolation duties. Review the design and connection dimensions below against your piping requirements.
For a project quotation, specify the medium, operating pressure and temperature, required shut-off performance and operating method. The proposed configuration should identify the materials, pressure class and applicable acceptance tests.
A triple eccentric butterfly valve specification should connect the required isolation duty with a defined construction and acceptance criteria.
State the operating and design conditions together with the process medium. Confirm the proposed body, disc and sealing materials against those conditions rather than selecting from the pressure class alone.
Specify whether shut-off is required in one direction or both. The quotation should identify the leakage acceptance criteria and test conditions for the proposed valve.
Confirm the required operating method, available installation space and connection dimensions. For an actuated assembly, include the control requirements and required failure position.
One-piece casting (plate welding) body, structure length in accordance with ISO5752, ASMEB16.10, and API609, can replace high-performance butterfly valves and other types of valves, simple installation, flexible all-metal structure plus zero leakage performance, so that the quality triple eccentric butterfly valve has intrinsic fire safety characteristics. We also offers China double eccentric butterfly valve for sale.
Stem anti-blow-out design is a safe and reliable triple eccentric butterfly valve, fully compliant with API609.
The butterfly valve triple eccentric position indicator on the stem and the top mounting flange are conducive to butterfly plate position indication.
The stem of the triple eccentric butterfly valve design adopts a through-shaft structure, and the connection between the stem and the butterfly plate adopts a key or pin key set.

The terms generally describe the same three-offset design principle. Individual products still differ in materials, construction and rated performance.
Check the service limits, material specification, shut-off requirements and acceptance tests for the proposed configuration. Ask for documentation relevant to the valve being supplied.
Provide valve size, pressure class, medium, operating temperature, required materials, operating method and quantity. Include the project datasheet when available.
