In November last year, a delegation from S&W Company, South Korea—including members of its Production Department, Technical Design Department, and China Office—visited Wenzhou, Zhejiang, to inspect and test valves at a partner manufacturing facility. During the on-site pressure testing of large valves, the team was highly impressed with the performance of the equipment used and expressed strong interest in procuring their own system for use at the company’s headquarters in South Korea.
The goal was to carry out sealing and pressure strength reliability tests on large ball valves and butterfly valves destined for the U.S. export market. While visiting the Wenzhou partner plant, S&W’s team evaluated multiple valve test bench manufacturers, comparing technical solutions, production capabilities, and industry reputation.
Ultimately, Zhejiang Youji Machinery Technology Co., Ltd. was selected, thanks to its proven technology and patented products (Patent No.: ZL 2014 2 0196239.6, with independent intellectual property rights).
Key Specifications of the Selected Model
- Maximum Clamping Force: 2,000 tons
- Maximum Valve Diameter: 96 inches
- Machine Weight: 110 tons
- Application: Large-diameter ball valves and butterfly valves
This model is currently China’s largest and most powerful valve test bench for export, setting a new benchmark for clamping capacity and overall scale in the international market.
The equipment was successfully delivered and installed in April at the S&W Valve Gyeongju Base in South Korea, reinforcing China’s position as a leader in large-scale valve testing technology worldwide.
