Shanghai Rogers Valve Co., Ltd. Secures Hydropower Project in Heilongjiang Province

Shanghai Rogers Valve Co., Ltd., a leading innovator in fluid control systems, was recently awarded a landmark contract to supply hydraulic control slow-closing check butterfly valves for a large-scale hydroelectric power station in Heilongjiang Province, China. The project involves the adaptation of 300 turbine inlet systems, marking a significant milestone in the company’s portfolio of critical infrastructure solutions.

Project Background
The Heilongjiang hydropower initiative, a key component of China’s renewable energy expansion strategy, required advanced flow control equipment capable of withstanding high-pressure conditions while ensuring operational reliability and longevity. Traditional systems utilizing separate check valves and gate valves posed challenges in maintenance efficiency, space optimization, and dynamic response to hydraulic transients.

Innovative Solution
Shanghai Rogers Valve proposed its flagship product, the Hydraulic Control Slow-Closing Check Butterfly Valve (HCV), as an integrated solution to replace conventional valve combinations. Engineered with precision, the HCV combines the functionalities of a check valve and a gate valve into a single, streamlined unit. Its core advantages include:

Intelligent Flow Management: The valve’s hydraulic control system enables precise regulation of closure speed, mitigating water hammer effects during turbine shutdowns, a critical requirement for protecting hydropower infrastructure.

Durability Under Extreme Conditions: Constructed with high-strength alloys and corrosion-resistant coatings, the valve is designed to operate reliably in the harsh, sediment-rich water environments typical of Heilongjiang’s river systems.

Operational Efficiency: By eliminating redundant components, the HCV reduces installation complexity, minimizes maintenance downtime, and optimizes energy loss across the turbine inlets.

Implementation & Impact
During the project’s execution phase, Shanghai Rogers Valve collaborated closely with the hydropower station’s engineering team to customize valve parameters, ensuring seamless integration with the turbines’ operational profiles. Post-deployment data indicated a 22% reduction in pressure surge incidents and a 15% improvement in maintenance cycle intervals compared to legacy systems.

This success underscores Shanghai Rogers Valve’s expertise in delivering mission-critical fluid control solutions for the energy sector. The Heilongjiang project not only reinforces the HCV’s technical superiority but also aligns with China’s strategic goals to modernize hydropower infrastructure and achieve carbon neutrality.

Shanghai Rogers Valve Co., Ltd. continues to pioneer advancements in valve technology, driving sustainable development across global energy networks.
