Offshore Marine Systems
For the LNG Bunkering System Project at Rotterdam Port Terminal,Netherlands, the main challenge was preventing cryogenic leakage during ship-to-ship transfers. The solution implemented involved extended bonnet cryogenic marine valves with vacuum insulation, successfully reducing boil-off gas to less than 0.1% per transfer.
HVAC System
For the Smart Green Building Fire Protection System in the Netherlands, 450 3-piece threaded electric ball valves and other accessories such as flexible tubes and fittings were installed. The valves modulate flow to maintain vessel pressure at 6–8 bar, resulting in 30% pump energy savings. In case of fire alarm activation, the valves fully open within less than 3 seconds via a hardwired relay.
Power Generation
For the petrochemical plant expansion project in Saudi Arabia, DELCO series shut-off pneumatic valves were primarily used in power generation applications. Key highlights include ATEX Zone 2 certification, an emergency response time of 0.4 seconds, and the ability to withstand ambient temperatures up to 55°C.
Oil & Gas Industry
For the Siberian Arctic Gas Pipeline Expansion Project (Yamotlor Field Operations), DELCO supplied Q-Series electric explosion-proof valves with smart integrated actuators, the connection form is flange, and the type is ball valve. These valves were chosen for their robust construction and certified safety, ensuring dependable performance in extreme arctic environments.
Electronic & Semiconductor Industry
GTI Project – Binh Duong Province, Vietnam. DELCO DK56 Series electric actuated butterfly valves were installed in our customer’s factories specializing in the production of electronic and semiconductor components. These valves play a critical role in the manufacturing process, ensuring reliable flow control and operational efficiency.
Pharmaceutical Industry
DELCO recently supplied 18 ZJHp Series diaphragm globe control valves for a pharmaceutical sterile water system in Germany’s life sciences research laboratory. Each pneumatic control valve features an FDA-compliant, electropolished 316Ti stainless steel body, delivering exceptional corrosion resistance and ensuring hygienic operation. The system achieves precise flow regulation with ±0.5% control accuracy, meeting the stringent requirements of pharmaceutical-grade applications.
DELCO VALVE CO., LTD
Quality is at the core of DELCO. We strictly implement the ISO9001: 2015 quality management system and hold certifications including CE, ROHS, SGS, FDA, and TUV. With more than 30 patents and strict testing procedures, every DELCO valve meets international standards.
