As a professional manufacturer with ISO9001 certification, Shanghai Zhibang Valve Manufacture Co., Ltd. is proud to present our CB/T590 Cast Steel Angle Globe Valve. Engineered for demanding industrial applications, this valve offers superior flow control and shut-off capabilities in high-pressure and high-temperature systems. Our commitment to quality, backed by years of experience since 2016, ensures that each valve delivers reliable performance, durability, and safety for critical processes worldwide. We understand the needs of global markets, from North America and Europe to Southeast Asia and Africa, and design our products to meet diverse operational standards and environmental conditions.
The CB/T590 series is specifically designed for applications where a change in flow direction is required, combining the functions of a valve and an elbow. The angle pattern design reduces pressure drop and minimizes pipe stress compared to standard globe valves. Key features and advantages include:
- Robust Construction: Manufactured from high-grade cast steel (typically WCB), offering excellent strength and resistance to thermal shock and mechanical stress.
- Precise Flow Regulation: The linear motion stem and disc design allows for fine throttling control and positive shut-off, minimizing seat wear.
- Enhanced Sealing: Features a metal-to-metal seat or optional hard-faced seats (Stellite) for superior leak-tightness in high-temperature services like steam.
- Durable Stem Packing: Utilizes high-quality graphite or PTFE packing rings, ensuring long-term stem sealing and reduced maintenance needs.
- Versatile Operation: Standard handwheel operation is ergonomic and easy to use. For larger sizes or high-pressure applications, bevel gear or electric/pneumatic actuators are available upon request.
- Easy Maintenance: The bolted bonnet design allows for straightforward in-line maintenance, seat replacement, and inspection without removing the valve body from the pipeline.

Frequently Asked Questions (FAQ)
-
Q: What is the main advantage of an angle pattern globe valve over a standard globe valve?
A: The primary advantage is its ability to change the flow direction by 90 degrees, effectively acting as both a valve and an elbow. This design reduces the number of fittings needed in a piping system, lowers pressure drop, and can help minimize pipe stress and turbulence at the valve outlet. -
Q: Can this valve be used for steam service?
A: Yes, it is well-suited for steam applications. When ordered for high-temperature steam service, we recommend specifying alloy steel body materials (like WC6 or WC9) and hard-faced trim (e.g., Stellite on seat and disc) to enhance resistance to erosion and galling. -
Q: What flange standards do you offer?
A: We commonly manufacture valves with ASME B16.5 (ANSI) or EN 1092-1 (DIN) flange dimensions. However, we can produce valves to other standards like JIS, GB, or AS 2129 based on customer request. Please specify your required flange standard and facing (RF, RTJ, FF) when inquiring. -
Q: Is the valve suitable for throttling or just on/off service?
A: While it provides excellent shut-off, the globe valve design is inherently good for throttling or regulating flow. The linear motion of the disc allows for precise control of the flow area. For frequent throttling duty, specifying a hardened trim is advisable to extend service life. -
Q: Do you provide actuated versions of this valve?
A: Absolutely. We can equip the valve with electric, pneumatic, or hydraulic actuators for automated control. The standard design includes a mounting pad for easy attachment of various actuator brands. Please provide your required torque, control signal, and power supply details for a complete automated package quote. -
Q: What is the lead time for an order of these valves?
A: Lead time depends on the order quantity, size, material specifications, and any special requirements. For standard configurations in common sizes, we typically maintain some inventory or can deliver within 4-6 weeks. We provide a confirmed delivery schedule upon order confirmation. -
Q: How do I determine the correct pressure rating (PN) for my application?
A: The PN rating must be equal to or greater than the maximum working pressure at the maximum working temperature of your system. Consider any potential pressure surges. Our technical team can assist you in selecting the appropriate pressure class (PN1.6 to PN6.4/Class 150 to 400) based on your process data. -
Q: What documentation is included with the valve shipment?
A: Each shipment is accompanied by a comprehensive documentation package, which typically includes a Material Test Report (MTR/Certificate of Conformity), hydro-test and pressure test certificates, detailed dimensional drawings, a maintenance manual, and a packing list. Certifications like ISO9001 are available upon request.
