Shanghai Zhibang Valve Manufacture Co., Ltd. is proud to present our Vertical Lift Check Valve specifically engineered for hydraulic station oil return lines. As a manufacturer established in 2016 with annual export value exceeding US$1 million, we combine precision manufacturing with rigorous quality control. This valve is designed to prevent backflow in hydraulic systems, ensuring smooth operation and extended equipment life. Each unit comes with a 1-year warranty and a Mill Test Report for full traceability and performance verification.
Our vertical lift check valve operates with a spring-loaded disc that lifts vertically when forward flow occurs, and closes instantly when flow reverses. This design minimizes pressure drop and water hammer, making it ideal for high-pressure hydraulic oil return applications. The valve body is manufactured from high-grade materials, offering excellent corrosion resistance and durability under demanding conditions.
Key Features & Technical Specifications
- Vertical Lift Mechanism: Ensures rapid response and low resistance to flow, reducing energy loss in the hydraulic circuit.
- Leak-Tight Seal: Metal-to-metal or soft-seat options available (customizable), providing zero leakage at rated pressure.
- Robust Construction: Body made from carbon steel or stainless steel, with hardened disc and seat for extended service life.
- Compact Design: Short face-to-face dimensions make it easy to install in confined spaces of hydraulic stations.
- Full Port Option: Available for minimal flow restriction, equivalent to pipe diameter.
- Mill Test Report Included: Each valve is hydrostatically tested and documented with a report for material, pressure, and sealing performance.
- 1-Year Warranty: Covers manufacturing defects, giving you peace of mind.

Advantages & Customer Benefits
- Reduced Maintenance: Self-cleaning vertical lift design prevents debris accumulation, extending service intervals.
- Energy Savings: Low cracking pressure (typically 0.05 bar) minimizes pump load and operational costs.
- Reliable Performance: Spring-assisted closing ensures positive shut-off even under low flow conditions.
- Easy Installation: Can be mounted in any orientation, though vertical installation is recommended for optimal operation.
- Comprehensive Testing: Every valve is hydrostatically tested at 1.5x rated pressure and seat leakage tested at 1.1x rated pressure. Mill Test Report is provided as standard.
- Customization: We offer adaptations for special end connections, materials, and pressure classes to meet your specific hydraulic system requirements.

Frequently Asked Questions
- What is the typical cracking pressure of this valve? The standard cracking pressure is 0.05 bar (0.7 psi). Custom spring settings are available for higher or lower values.
- Can this valve be used for water or other fluids? Yes, it is suitable for hydraulic oil, lubricating oil, water, and other non-corrosive fluids. For aggressive media, please consult us for material upgrades.
- Is the Mill Test Report included for every valve? Yes, each valve comes with a Mill Test Report documenting material, pressure test results, and sealing performance. Additional third-party inspection can be arranged.
- What is the warranty coverage? We offer a 1-year warranty against manufacturing defects. The warranty covers replacement or repair of the valve, excluding misuse or wear of consumable parts.
- Can I get a custom size or pressure rating? Absolutely. We can customize sizes from 1/2” up to 12”, and pressure ratings up to ANSI 600# or PN64. Lead time depends on specification.
- How do I install the valve correctly? For optimal performance, install the valve vertically with the flow arrow pointing upward. However, horizontal installation is also acceptable if the spring is strong enough. Refer to the installation manual included with the valve.
- Do you provide samples for testing? Yes, samples are available. Please contact our sales team to discuss sample policy and shipping costs.
- What is the typical lead time for bulk orders? For standard sizes, lead time is 15–25 working days after deposit. Custom orders may require 30–45 days depending on complexity.
