Zhejiang Youji Machinery Technology Co., Ltd. is pushing forward the project of custom control valve and throttle valve test benches for the Thailand control valve manufacturing plant of Curtiss-Wright Corporation (US). This collaboration continues the long-term technical exchange and business partnership between both parties, demonstrating Zhejiang Youji’s technical expertise and service capacity in custom high-end valve testing equipment.
The cooperation dates back to 2020, when Curtiss-Wright’s Chinese subsidiary, Curtiss-Wright (Tianjin) Fluid Controls Co., Ltd., placed its first order for valve testing equipment from Zhejiang Youji. The partnership has since deepened continuously, with a total of 7 sets of test equipment for control valves, throttle valves and safety valves ordered in successive batches. From the initial purchase and repeated reorders in China to the current support for its overseas manufacturing base in Thailand, it fully reflects the international giant’s high recognition of Zhejiang Youji’s product quality, technical solutions and delivery services.

Widely adopted in energy, chemical and industrial fluid control systems, control valves and throttle valves impose stringent requirements on testing equipment in terms of measurement accuracy, operational stability, safety protection and customization capability. Oriented toward customers’ actual working conditions, Zhejiang Youji delivers professional testing solutions tailored to varied valve structures, test specifications and production workflows, helping clients improve product quality and inspection efficiency.
As a National High-tech Enterprise, Zhejiang Youji is listed in Zhejiang Provincial Specialized & Innovative Cultivation Enterprise and Zhejiang First-set Equipment Catalogue, and honored with titles including Zhejiang Advanced Manufacturing Accreditation and “Wenzhou Quality Product”. The company keeps innovating intelligent valve testers, large-size valve seal grinding machines and valve life-cycle test equipment.
