Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our Ship Oil Pipeline Check Valve with Dual Plate Design, specifically engineered for lubricating oil and hydraulic oil systems aboard marine vessels and offshore installations. As a dedicated manufacturer with ISO9001 certification and over eight years of experience, we combine precision engineering with robust materials to deliver a valve that ensures reliable backflow prevention and minimal pressure drop. Our dual plate check valve is designed to meet the demanding requirements of oil pipelines, offering compact construction and easy installation.
This check valve features a spring-assisted dual plate mechanism that closes quickly upon flow reversal, protecting pumps and compressors from damaging reverse flow. The lightweight wafer style body reduces weight and space requirements, making it ideal for congested engine rooms and piping systems. Manufactured from high-grade cast steel or stainless steel, the valve resists corrosion from lubricating and hydraulic oils, ensuring long service life even in harsh marine environments.
Key Features & Technical Specifications:
- Dual Plate Design: Provides quick closing action, reduces water hammer, and minimizes pressure loss.
- Compact Wafer Body: Saves space and weight, installs easily between flanges.
- Spring-Loaded Plates: Ensure positive sealing even at low flow rates.
- Material Options: Cast steel (WCB), stainless steel (CF8/CF8M), and customizable per request.
- Pressure Ranges: PN10, PN16, PN25, PN40 or Class 150, 300 (available upon request).
- End Connections: Wafer type (standard), lug type or flanged on request.
- Applicable Standards: Designed according to API 594 and ISO 9001 quality management system.
- Temperature Range: -20°C to +120°C, with high-temperature options available.
- Media Compatibility: Suitable for lubricating oil, hydraulic oil, fuel oil, and other petroleum-based fluids.

Frequently Asked Questions (FAQ)
1. What is the main advantage of a dual plate check valve over a swing check valve?
Dual plate check valves have a much shorter closing stroke, which reduces water hammer and pressure surges. They are also more compact and lightweight, ideal for tight spaces in ship piping.
2. Can this valve be used for both lubricating oil and hydraulic oil systems?
Yes, the materials used (carbon steel, stainless steel, PTFE seals) are compatible with mineral oils, hydraulic oils, and lubricants. For special synthetic oils, please consult our engineers for material recommendations.
3. What is the maximum operating temperature?
Standard range is -20°C to +120°C. For higher temperature applications, we can provide valves with high-temperature seals (e.g., graphite) – please specify when ordering.
4. Do you offer flanged connections instead of wafer?
Yes, we can supply lug-type or full flanged ends upon request. The wafer design is standard for space saving, but we customize per customer requirement.
5. What are the delivery times for a typical order?
Standard sizes in stock can ship within 7–15 days. Custom orders typically require 20–35 days depending on quantity and specifications.
6. Is this valve suitable for vertical piping?
Yes, it can be installed horizontally or vertically with upward flow. For vertical downward flow, please contact us for proper spring selection.
7. Do you provide test certificates or material reports?
Absolutely. Each valve comes with a Material Certificate and Pressure Test Report as standard. Third-party inspection is welcome and can be arranged at extra cost.
8. What is the minimum order quantity?
Our MOQ is 1 piece for standard sizes. For customized products, minimum order may be 5–10 pieces – please inquire with our sales team.
