Product Description
Custom-Manufactured Hydro-Turbine Bypass Valve for Hydropower Plants
The bypass valve is an essential safety component of hydro-turbine water conveyance systems. Its main functions include balancing pressure difference between upstream and downstream of the main inlet valve prior to main-valve opening, and diverting partial flow during emergency load rejection to restrain water-hammer pressure rise inside penstock and spiral case, preventing pipeline and turbine over-pressure failure.
Poor sealing, cavitation damage, or unresponsive action of bypass valves can lead to difficult main-valve operation, excessive water-hammer pressure, pipeline stress overload, and severe hidden dangers to hydropower station safe operation.
We deliver tailor-made bypass valve solutions strictly based on customer drawings, nominal pressure, nominal diameter, design flow, actuator mode, and actual site working conditions.
Main Technical Features
- High-strength cast steel valve body: Optimized flow-passage structure withstands high water pressure and transient water-hammer impact with good rigidity and no deformation under alternating hydraulic load.
- Anti-cavitation & anti-abrasion trim: Special flow-passage design effectively restrains cavitation and flow-induced vibration, extending service life in high-head dynamic water operating environments.
- High-reliability sealing assembly: Hard-faced sealing surfaces achieve low-leakage shut-off performance, stable for long-term intermittent operation in hydropower stations.
- Multiple actuator options: Hydraulic or electric actuators available with interlock & linkage control capabilities with turbine governor to satisfy emergency opening-closing logic requirements.
- Full customization service: Nominal pressure, diameter, flange standards, connection sizes, actuator installation interfaces, and control signals can be customized for new-build, retrofit, and overhaul projects. Every finished valve passes hydrostatic strength testing, tightness testing, and full-stroke functional commissioning before leaving the factory.
Application Scope
- Hydraulic valve equipment supply for newly-built hydropower stations
- Water conveyance system upgrading and retrofitting of existing turbine-generator sets
- Overhaul replacement spare parts for Francis, Kaplan, bulb, and pumped-storage reversible units
- Medium-large hydropower plants, EPC contractors, and power-asset operators worldwide
Our Services
- Custom design & fabrication according to customer drawings or technical specifications
- Structural optimization for high-head, heavy-water-hammer working scenarios
- Complete factory tests: strength test, sealing test, full-stroke operation test
- Technical support for on-site installation, commissioning, and operation-maintenance guidance
Please provide pressure-grade, diameter parameters, or drawings. We will prepare targeted technical proposals and quotations for you.
