As a professional manufacturer with a solid foundation in industrial valve production since 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents the CB/T590 Cast Steel Angle Globe Valve. Engineered specifically for the demanding environments of marine fuel and steam systems, this valve combines robust construction with precise flow control. We understand the critical need for reliability and safety in shipboard applications, which is why our angle globe valve is designed to offer superior shut-off performance and long service life, contributing directly to the operational efficiency and safety of your vessel's vital systems.
Our CB/T590 Angle Globe Valve is a cornerstone product for marine piping, featuring a distinct 90-degree angle body design that offers significant installation and performance benefits over straight-pattern valves.
- Optimized Flow Path & Reduced Pressure Drop: The angled body design allows for a more natural change in flow direction, minimizing turbulence and pressure loss compared to standard globe valves. This results in improved system efficiency, especially in fuel transfer and steam distribution lines.
- Robust Cast Steel Construction: Manufactured from high-quality carbon steel casting, the valve body and bonnet provide exceptional strength and durability to withstand high pressures, mechanical shocks, and the corrosive marine atmosphere.
- Reliable Sealing & Tight Shut-off: The valve employs a precision-machined stainless steel disc and seat arrangement. The parallel or tapered seat design ensures bubble-tight sealing when fully closed, preventing leakage in critical fuel and steam services—a non-negotiable requirement for ship safety.
- Enhanced Serviceability & Space Saving: The angle pattern often allows for easier inline maintenance and inspection. Furthermore, its design can save valuable space in crowded engine rooms and pipe racks by eliminating the need for additional pipe elbows.
- Versatile Stem Packing Options: To suit various service temperatures and media, the valve is equipped with adjustable gland packing. Options include flexible graphite for high-temperature steam applications or PTFE for lower temperatures and a wider chemical compatibility range.
- Multiple Operation & Connection Choices: Available with a standard handwheel for manual operation or an optional gearbox for larger sizes or high-torque applications. Connection ends are typically flanged per relevant standards (JIS, DIN, ANSI), with threaded ends available for smaller sizes upon request.

Frequently Asked Questions (FAQ)
Q1: What is the primary advantage of an angle pattern globe valve over a standard straight pattern?
A: The main advantage is the integrated 90-degree turn in the flow path. This design reduces pressure drop, saves space by eliminating an elbow fitting, and can simplify installation and maintenance in tight spaces common on ships.
Q2: Is this valve suitable for both fuel oil and steam service?
A: Yes, it is specifically designed for such applications. However, the specific material trim (e.g., seat/disc material) and packing selection should be confirmed based on the exact service temperature, pressure, and media properties to ensure optimal performance and longevity.
Q3: What pressure classes and sizes are typically available from stock?
A: We commonly stock sizes from DN15 to DN100 (1/2" to 4") in PN16/Class 150 and PN25/Class 150 ratings. Larger sizes and higher pressure classes (like PN40/Class 300) are produced per order. Please inquire for specific availability.
Q4: Can you provide valves with different flange standards, such as ANSI or JIS?
A: Absolutely. While our standard follows Chinese GB standards, we regularly produce valves with ANSI, JIS, DIN, or other international flange face dimensions and drilling standards to meet global project requirements.
Q5: What kind of testing do these valves undergo before shipment?
A: Each valve undergoes a hydrostatic shell test at 1.5 times the rated pressure and a seat leakage test per standards like GB/T 13927 or API 598. Additional tests, such as fire-safe testing, can be arranged upon request.
Q6: Do you offer actuated versions of this angle globe valve?
A: Yes, we can provide electric, pneumatic, or hydraulic actuators as an optional feature. The valve design allows for easy integration with various actuator types for remote or automated control.
Q7: What is the typical lead time for a custom order?
A: Lead time depends on the order quantity, size, material specifications, and any special requirements. For standard configurations, it generally ranges from 30 to 60 days. We provide a precise timeline upon receipt of your detailed inquiry.
Q8: How does your ISO9001 certification benefit the customer?
A: Our ISO9001 certification ensures a consistent, documented, and controlled manufacturing process. This translates into reliable product quality, traceability of materials and processes, and a systematic approach to meeting customer requirements and continuous improvement.
