Flange Cast iron globe valves

Flange cast iron globe valves are a type of globe valve that is constructed with a cast iron body and flanged ends. They are commonly used in applications where a reliable shut-off or throttling of the flow is required. Here are some key features and information about flange cast iron globe valves:

1. Construction: Flange cast iron globe valves have a sturdy construction with a body made of cast iron. Cast iron is known for its durability, strength, and resistance to corrosion, making it suitable for various industrial applications.

2. Flanged Ends: These valves have flanged ends, which allow for easy installation and connection to the pipeline. The flanges provide a secure and leak-free connection when bolted to corresponding flanges on the pipeline.

3. Globe Valve Design: Flange cast iron globe valves have a globe valve design, which consists of a movable disc or plug (the "disk") and a stationary ring seat. The disk is connected to a stem, which is operated by a handwheel, gearbox, or actuator. When the stem is turned, the disk moves up or down to control the flow through the valve.

4. Flow Regulation: Globe valves are commonly used for flow regulation, allowing precise control over the flow rate. By adjusting the position of the disk, the flow can be throttled or completely shut off. The globe valve design provides good flow characteristics, resulting in minimal pressure drop across the valve.

5. Suitable Applications: Flange cast iron globe valves are widely used in various industries, including water treatment, HVAC systems, power plants, oil and gas, chemical processing, and more. They are suitable for handling a wide range of fluids, including water, steam, oil, gases, and corrosive media.

6. Pressure and Temperature Ratings: Flange cast iron globe valves come in different pressure ratings, typically ranging from ANSI 125 to ANSI 250. The temperature range for these valves depends on the specific design and materials used.

7. Accessories and Options: Flange cast iron globe valves can be equipped with various accessories and options to enhance their performance, such as positioners, limit switches, solenoid valves, and pneumatic or electric actuators. These additions enable remote control, automation, and integration into larger systems.

When selecting a flange cast iron globe valve, it's important to consider the specific requirements of your application, such as pressure, temperature, flow rate, and media compatibility. Additionally, ensure that the valve meets relevant industry standards and regulations to ensure safe and efficient operation. Consulting with a valve supplier or an engineer with expertise in valves can help you choose the right valve for your needs.
