Shanghai Zhibang Valve Manufacture Co., Ltd. has been a trusted manufacturer of industrial valves since 2016, delivering high-performance solutions to global markets. Our Marine High Pressure Globe Check Valve is specifically engineered for offshore platform hydraulic systems, where reliability and safety under extreme conditions are non-negotiable. Built from premium forged steel with PN16 rating, this valve ensures leak-tight sealing, minimal pressure drop, and long service life even in saltwater environments. Discover why engineers across North America, Europe, and Asia choose Zhibang for critical marine applications.
Product Features & Benefits
- Forged Steel Construction: Superior strength and corrosion resistance compared to cast valves, ideal for high-pressure hydraulic circuits.
- PN16 Pressure Rating: Designed for working pressures up to 16 bar (232 psi), with optional higher ratings available.
- Globe Check Design: Combines globe valve throttling capability with check valve backflow prevention, reducing system complexity.
- Marine-Grade Coating: Special anti-corrosion epoxy paint protects against seawater, humidity, and chemical exposure.
- Compact Flanged Ends: Easy installation in space-constrained offshore skids; flanged connections per ASME B16.5 (RF or RTJ).
- Leak-Free Sealing: Precision-machined seats and PTFE or metal seals ensure Class VI shutoff.
- Full Bore Option: Available for lower pressure drop when system demands high flow rates.
- Wide Size Range (DN15-DN100): Covers most hydraulic line requirements without extra adapters.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between a globe check valve and a standard check valve?
A: A globe check valve integrates a globe-style throttling disc with a check mechanism, allowing flow regulation while preventing backflow. It is ideal for systems requiring both functions in a single valve body, saving space and reducing potential leak points. -
Q: Can this valve be used for seawater or corrosive fluids?
A: Yes. The forged steel body with marine-grade epoxy coating provides excellent resistance to seawater corrosion. For more aggressive media, we can provide stainless steel trim or all-stainless construction. Please consult our engineers for specific fluid compatibility. -
Q: What is the maximum working pressure for PN16 rating?
A: PN16 corresponds to a nominal pressure of 16 bar (232 psi) at ambient temperature. However, actual allowable pressure depends on temperature and material. For higher pressure requirements, we offer PN25, PN40, or Class 300 options. -
Q: Do you provide third-party testing or certification?
A: Yes. We can arrange third-party inspection (e.g., Lloyd’s, DNV, Bureau Veritas) at additional cost. Our standard quality documentation includes material certificates (EN 10204 3.1), hydro test reports, and dimensional reports. -
Q: What are the available end connections?
A: Standard is flanged according to ASME B16.5 (RF or RTJ). Threaded ends (NPT or BSP) and socket weld ends are available as special order. Flange drilling can be customized (e.g., EN 1092-1) upon request. -
Q: How do I select the correct size for my hydraulic system?
A: Size selection depends on flow rate, pressure, and acceptable pressure drop. We recommend providing your system’s flow (e.g., L/min) and operating pressure. Our technical team can perform valve sizing calculations to ensure optimal performance. -
Q: What is the lead time for this valve?
A: For standard sizes (DN15-DN100) with carbon steel materials, typical lead time is 15-25 working days. Custom materials or special trim may require 30-40 working days. We offer express services for urgent orders (additional fees apply). -
Q: Do you offer a warranty and after-sales support?
A: Yes. We provide a 12-month warranty against manufacturing defects. Our after-sales team offers technical support via email and phone. Spare parts (seals, disc, stem) are available for quick replacement.
