2009

TPU liner

The introduction of polyurethane liner for the first time in slurry valves, significantly improved wear resistance and sealing stability in slurry application.

2010

CPU Liner Innovations

After material comparison in the laboratory and field, the CPU(cast polyurethane) performed better in slurry applications than TPU(thermoplastic polyurethane). We decided to develop CPU liner patterns for the whole series replacing all the TPU patterns we had developed from the beginning. A packing block was also added to minimize the leakage between the liner and the packing.

2011-2012

Enhanced Sealing Solutions

Liner sealing face was enlarged, to further improve leak prevention and ensure long-term reliability.

2016

PU Material Standardization

We upgraded to a more durable polyurethane material, unified our suppliers, and standardized the material color to green, enhancing consistency and performance.

2017

Secondary Seal

A secondary seal was added to the valve body, terminated any chance of the leakage to the environment.

2019

Yoke Structure Modernization

The yoke structure was updated，replacing rods with welded brackets and adding a position indicator, improving stability and installation flexibility.

2025

Innovation at the Core

We embrace continuous innovation, iterating designs to meet market demands with wear- and corrosion-resistant solutions.
