The bellows pressure relief valve 5.7A25 is engineered for overpressure protection in hydraulic and oil systems, particularly in power plant EH (electro-hydraulic) control circuits. This model is designed to relieve excess pressure by diverting fluid when system pressure exceeds the setpoint, safeguarding downstream components. The 5.7A25 designation indicates a specific series optimized for rapid response and precise pressure control in dynamic systems.
The valve body is typically forged from carbon steel or stainless steel, with a bellows assembly made of stainless steel 316L to resist corrosion from hydraulic fluids. The pressure relief mechanism uses a spring-loaded poppet or piston, with typical setpoints ranging from 10 to 35 MPa depending on the application. Standard industry practices for such valves include compliance with ISO 6292 or ASME B16.34 for dimensional and performance criteria, though the supplier should provide exact specifications.
This valve is commonly deployed in power stations to protect pumps, actuators, and pipelines in EH oil systems and turbine control circuits. Buyers in the energy sector source these components to replace aging parts or upgrade system reliability. The supplier offers this as part of a broader inventory of power plant spares, with the valve supplied in individual packaging or bulk crates. Confirm the set pressure, cracking pressure, and reseat pressure values to ensure compatibility with your system.

Sourcing bellows Pressure relief valve 5.7A25 from Deyang Dongfang Yoyik Engineering Co., Ltd. - China Import Guide
Before placing an order, verify the valve’s set pressure, cracking pressure, and reseat pressure to ensure they match your system’s requirements. Request material certifications for the body, bellows, and seals to confirm compatibility with your hydraulic fluid. For critical applications, ask for third-party test reports or witnessed performance tests to validate the valve’s reliability under your operating conditions.
Discuss packaging and preservation methods with the supplier to prevent contamination or damage during transit, particularly for valves with sensitive bellows assemblies. Clarify Incoterms, such as FOB Deyang or CIF to your destination port, and confirm lead times, as specialized valves may require 12 to 16 weeks for production. Payment terms often include a 30% deposit, with the balance due prior to shipment, but these can be negotiated based on order volume.
Upon delivery, inspect the valve for external damage and verify that the set pressure matches the purchase order specifications. Conduct a functional test at the supplier’s recommended pressure to ensure the valve opens and reseats correctly. For valves intended for high-pressure or high-cycle applications, consider additional non-destructive testing, such as pressure decay tests or ultrasonic inspection of the bellows. Retain all test documentation for future reference and compliance.
