As a professional valve manufacturer based in Shanghai, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our CB/T590 Forged Steel High Pressure Angle Globe Valve. Engineered for demanding applications, this valve combines robust forged steel construction with a reliable flanged design, making it an ideal choice for high-pressure steam, water, oil, and gas pipelines where durability and precise flow control are paramount. With our ISO9001-certified manufacturing processes and a commitment to quality since 2016, we deliver valves that meet rigorous industrial standards, ensuring safety and efficiency for your critical operations worldwide.
Our CB/T590 Angle Globe Valve is specifically designed to handle the challenges of high-pressure systems. The forged steel body provides superior strength and resistance to pressure-induced stress compared to cast alternatives. The unique 90-degree angle design offers significant advantages over straight-pattern globe valves, including reduced flow resistance, lower pressure drop, and a more compact installation footprint, which simplifies piping layouts and saves valuable space.
- Superior Forged Construction: The valve body, bonnet, and key components are forged from high-quality carbon or alloy steel. This manufacturing process results in a denser grain structure, offering enhanced mechanical properties, better impact resistance, and greater integrity under high-pressure and high-temperature conditions.
- Optimized Angle Flow Path: The flow enters the valve horizontally and exits vertically (or vice-versa), creating a smooth directional change that minimizes turbulence and erosion on the seat and disc. This design extends service life, especially in applications involving saturated or superheated steam.
- Reliable Sealing & Shut-off: Features a plug-type disc and seat arrangement. The disc can be equipped with Stellite hardfacing or other hardened materials upon request, providing excellent wear and galling resistance for bubble-tight shut-off, even after numerous cycles.
- Robust Stem & Packing: A rising stem design with a fine-pitch trapezoidal thread ensures precise and smooth operation. The stem packing system typically utilizes flexible graphite or braided asbestos-free packing, ensuring a reliable seal against stem leakage under high pressures.
- Versatile Flanged Connections: Available with RF (Raised Face) or RTJ (Ring Type Joint) flanges as per standard specifications like ANSI B16.5, ensuring easy and secure integration into your existing flanged piping systems from DN15 to DN50.
- Wide Application Suitability: Engineered for a broad spectrum of services including boiler feedwater systems, steam lines, high-pressure water supply, chemical processing, and power generation plants.

Frequently Asked Questions (FAQ)
Q1: What is the main advantage of an angle globe valve over a straight pattern globe valve?
A: The primary advantage is the 90-degree flow path. This design significantly reduces flow resistance and pressure drop, minimizes turbulence that can cause seat erosion, and allows for a more compact installation, often eliminating the need for an extra pipe elbow.
Q2: Can this valve be used for both throttling and isolation (on/off) service?
A: Yes, angle globe valves are well-suited for both functions. They offer good throttling characteristics for flow regulation and provide reliable shut-off when fully closed, especially with hardened trim options.
Q3: What materials are available for the seat and disc to handle erosive or high-temperature media?
A: Standard trim is often 13Cr stainless steel. For highly erosive or high-temperature services like superheated steam, we recommend optional Stellite (cobalt-chromium alloy) hardfacing on the seat and disc faces, which greatly enhances wear and galling resistance.
Q4: Are the flanges compliant with international standards like ANSI or DIN?
A> Yes. While the valve is manufactured to the Chinese CB/T590 standard, the flanged ends are typically produced to match common international dimensions such as ANSI B16.5 Class 150/300/600 or equivalent DIN standards, ensuring compatibility with global piping systems. Specific flange standards can be confirmed upon order.
Q5: What is the typical lead time for an order of these valves?
A: Lead time depends on the order quantity, specific material grades, and pressure class. For standard configurations, we generally maintain a competitive lead time. Please contact our sales team with your detailed requirements for an accurate production schedule.
Q6: Do you offer any other operation methods besides manual handwheel?
A: Absolutely. While manual operation is standard, we can provide this valve design equipped with gear operators for high-torque applications, or with pneumatic/hydraulic actuators for automated remote control. These are customizable options.
Q7: What kind of testing and inspection do these valves undergo before shipment?
A: Each valve undergoes rigorous testing, which typically includes hydrostatic shell tests (at 1.5 times the rated pressure) and seat leakage tests per applicable standards (e.g., API 598). Inspection reports and certificates are available upon request.
Q8: My application involves cyclic thermal shock. Is this valve suitable?
A: The forged steel construction offers good resistance to thermal stress. For severe cyclic thermal shock applications, we advise discussing the specific temperature cycles and media with our engineering team. Material upgrades (e.g., to higher-grade alloy steel) and specific design considerations can be evaluated to ensure suitability.
