As a leading manufacturer with a strong commitment to quality and reliability, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our premium line of API 6D Certified Forged Steel Ball Valves, engineered specifically for the demanding environments of high-pressure shipboard piping systems. Since our establishment in 2016, we have dedicated ourselves to producing industrial valves that meet the highest international standards, ensuring the safety and efficiency of critical maritime operations. Our valves are the result of advanced forging techniques, rigorous testing, and a deep understanding of the challenges faced in offshore and marine applications. We combine robust construction with precision engineering to deliver a product that offers exceptional sealing performance, long service life, and minimal maintenance requirements, making it an ideal choice for shipbuilders, shipyards, and marine engineering firms worldwide.

This valve is designed to be the reliable backbone of your ship's fluid handling systems, handling everything from fuel and lube oil to seawater and ballast with unwavering integrity.

Superior Forged Construction: The body, bonnet, and ball are forged from high-grade carbon steel (A105, LF2), providing superior mechanical strength, impact resistance, and structural integrity compared to cast alternatives. This forging process eliminates internal defects like porosity and shrinkage, ensuring reliability under the high cyclic stresses and pressure surges common in marine environments.
API 6D Certification & Compliance: The valve is fully designed, manufactured, and tested in compliance with API 6D specification for pipeline valves. This certification is a testament to its performance in full bore or reduced bore design, pressure containment, and operational safety, which is a critical requirement for class-approved shipboard installations.
Robust High-Pressure Design: Engineered for service in Class 150 through Class 2500 pressure ratings, the valve features a reinforced body structure, high-strength stem with anti-blowout design, and advanced sealing systems to prevent leaks and ensure safe operation even under the most extreme pressure conditions encountered at sea.
Enhanced Sealing for Marine Duty: We offer a range of seat materials to suit various media. Standard PTFE seats provide excellent sealing and low torque. For more abrasive services or higher temperatures, reinforced PTFE or metal seated (fire-safe) designs are available. The chrome-plated or stainless steel ball ensures a smooth, low-friction operation and excellent corrosion resistance against seawater and other shipboard fluids.
Versatile Actuation & Configuration: The valve can be supplied with a standard lever for manual operation or can be easily fitted with pneumatic, electric, or hydraulic actuators for remote control and automation integration into the ship's control system. Gear operators are available for larger sizes to reduce operating torque.
Fire-Safe Capability: Optional fire-safe design per API 607/6FA standards ensures that in the event of a fire, the valve maintains a seal, preventing the escalation of the emergency—a non-negotiable safety feature for fuel and flammable fluid lines on vessels.

Here is a summary of key technical specifications for common models:

Size (inch)	Pressure Class	Body Material	Test Pressure (Hydro)	Standard Port
1/2" - 2"	Class 150 - 600	A105 Forged Steel	1.5 x Rating	Full Bore
2 1/2" - 8"	Class 150 - 900	A105 / LF2 Forged Steel	1.5 x Rating	Full or Reduced Bore
10" - 24"	Class 150 - 600	LF2 Forged Steel	1.5 x Rating	Reduced Bore (Standard)

Benefits for Your Operations:

Maximized System Uptime: The forged steel construction and reliable sealing minimize the risk of in-service failures, reducing unscheduled downtime for repairs—a critical factor for vessel operational efficiency.
Long-Term Cost Savings: Durable materials and design lead to an extended service life, lowering the total cost of ownership by reducing replacement frequency and maintenance costs over the lifespan of the vessel.
Simplified Compliance & Classification: The API 6D certification and optional fire-safe approvals facilitate the process of obtaining necessary class approvals from maritime authorities (e.g., ABS, DNV, Lloyd's Register), speeding up your project timelines.
Operational Safety Assurance: The high-integrity design provides peace of mind, knowing that critical piping systems are secured with valves built to contain pressure and prevent leaks under challenging sea conditions.

Frequently Asked Questions (FAQ)

Q: What is the significance of API 6D certification for a shipboard valve?
A: API 6D is a specification from the American Petroleum Institute specifically for pipeline and piping valves. Certification to this standard ensures the valve is designed, manufactured, and tested for performance in demanding service, including full pressure containment, structural strength, and operational cycles. For shipboard use, it is often a requirement for class approval from marine regulatory bodies, guaranteeing a recognized level of quality and safety.
Q: Can this valve handle seawater service?
A: Yes, it is well-suited for seawater service. The forged carbon steel body provides good strength, and we recommend specifying appropriate internal trim materials like stainless steel ball and stem along with corrosion-resistant seat materials. Proper external coating or cathodic protection strategies should also be considered for long-term immersion or splash zone exposure.
Q: What types of end connections are available?
A: We offer a variety of end connections to match your piping system: flanged ends (Raised Face RF or Ring Type Joint RTJ) are most common for shipboard piping, but threaded (NPT) and socket weld ends are also available for smaller sizes or specific applications.
Q: Is the valve suitable for cryogenic service on LNG carriers?
A: The standard valve is rated for temperatures down to -29°C (-20°F). For cryogenic applications like LNG (down to -196°C), a specially designed cryogenic ball valve with extended bonnet, low-temperature materials, and modified seals is required. Please inquire about our cryogenic valve series for such applications.
Q: Do you provide actuated versions for remote operation?
A: Absolutely. The valve can be supplied as a manual unit or pre-fitted with pneumatic (double-acting or spring-return), electric, or hydraulic actuators. We can assist in selecting the right actuator based on your available power source, required operating speed, and fail-safe needs.
Q: What is the delivery lead time for an order?
A: Lead time varies based on valve size, pressure class, material trim, and quantity. Standard configurations typically have shorter lead times. We provide estimated lead times upon receipt of your detailed inquiry and work to meet your project schedule through our efficient manufacturing and global logistics from ports like Shanghai and Hong Kong.
Q: How does the fire-safe design work?
A: In a fire-safe design (per API 607/6FA), the primary soft seats (e.g., PTFE) are backed by secondary metal seals. In a fire, the primary seats may degrade, but the metal-to-metal contact between the ball and the body/seat holder creates a secondary seal, preventing major leakage and helping to contain the fire.
Q: Can you provide documentation for class approval?
A: Yes. We can provide essential documentation including Material Test Certificates (MTC/CMTR), pressure test reports, API 6D certification, and ISO9001 certificate to support your submission to classification societies like ABS, DNV, BV, etc.
