D342X Double Eccentric Butterfly Valve
Low Operating Torque & Extended Seal Life
The tilted disc design releases compression stress early during opening, resulting in low operating torque and extended sealing life.
Fixed Disc to Prevent Fluttering and Wear
The disc is rigidly fixated to prevent fluttering and wear during operation, ensuring stable long-term performance.
Premium Seal Profile for Low Torque and Reliable Tightness
The seal profile and premium rubber quality ensure low closing torque and excellent sealing reliability.
Comprehensive Anti-Corrosion Design for Durability
The ductile iron body and disc with epoxy coating, combined with O-ring protection on bolt holes and shaft ends, ensure corrosion resistance and long-lasting durability.
Multi-Certified for Broad Industrial Use
Rubber components are multi-approved; the valve complies with DIN 30677-2 and GSK standards, suitable for water supply, wastewater treatment, and industrial systems.

- Applications
Municipal Water Supply & Wastewater Treatment
The double-offset butterfly valve, with its excellent sealing, low torque and corrosion-resistant design, is ideal for water supply networks, drainage systems and sewage treatment applications.
HVAC & Cooling Water Circulation Systems
Its low operating torque, easy maintenance and long service life make it well-suited for HVAC systems and cooling water circulation applications.
Industrial Process Water, Chemical & Mildly Corrosive Media
Suitable for transporting clean, neutral or mildly corrosive fluids in industries such as chemical, pharmaceutical, paper and food under non-extreme conditions.
Isolation & Shut-off in Moderate Pressure, Ambient Temperature Conditions
In systems with moderate pressure and temperature (e.g., up to PN40, temperature up to ~150°C), double-ffset valves can deliver high-performance shut-off.
Environments with Light Solids, Mild Erosion Conditions
While not designed for heavy erosion or extreme particulate loads, these valves perform well in pipelines with light solids and low erosion conditions.

KHOBI II Hydro Power Project in Georgia
- Samegrelo-zemo Svaneti district, Chkhorotsku district, Georgia, Khobistskali river.
Customer/Owner: Ministry of Agriculture, Malawi
- Working conditions/Challenges:
This hydropower station is the largest one built by Georgia after its independence following the disintegration of the Soviet Union. The annual power generation is approximately 202 million kWh, which can meet the electricity demand of about 50,000 households. The engineering project includes equipment such as water diversion systems, waterway tunnels, pressure pipelines, and hydraulic control butterfly inlet valves.
- The type of equipment adopted:
Based on the project’s process drawings and multiple communications and discussions with the project’s engineers, we provided a complete set of equipment solutions for the project and delivered a full range of valves and accessories including DN2400 hydraulic control butterfly valves, joints, filters, exhaust valves, etc. During the installation stage of the project, we dispatched engineers to the site to guide the installation.
Key indicators: The on-site pipeline for the project design was a non-standard size of DN2300. We provided the client with a solution of DN2400 valves and DN2400*2300 flange reducers, which not only ensured the on-site pipeline connection but also saved project costs.
Achievements/advantages: On October 31, 2024, it was officially opened after a ceremony presided over by Georgian Prime Minister Irakli Kobakhidze.
