Product Overview

దిDurable Ductile Iron Flanged Globe Valve is a high performance manual shut-off valve designed for reliable flow regulation and isolation in water, నూనె, gas and steam piping systems. Using a sturdy WCB carbon steel/ductile iron valve body with 13Cr stainless steel hardened disc and stainless steel stem (A182F6a), it provides excellent wear resistance, sealing performance and long service life in harsh industrial environments. It is suitable for a wide range of industrial applications such as power generation, chemical processing, oil and gas, and HVAC.

Technical Specifications

Durable Ductile Iron Flanged Globe Valve

Working Principle

The globe valve operates by raising or lowering a disc (ప్లగ్) relative to the stationary seat, controlling the flow of media through the valve. The handwheel turns the stem, which moves the disc up and down:

• Valve Closed: The disc is lowered onto the seat, creating a tight seal that stops flow completely.
• Valve Open: The disc is raised from the seat, allowing media to flow through the valve body.
• Throttling: The disc can be positioned at any point between fully open and fully closed, enabling precise flow regulation.

తరచుగా అడిగే ప్రశ్నలు

Q1: What is the difference between a globe valve and a gate valve?

ఎ: Globe valves are used for flow regulation and shut-off; they offer good throttling characteristics but result in a higher pressure drop. Gate valves are primarily used for full-open or full-closed (on/off) సేవ; they have minimal pressure drop but are unsuitable for throttling. For applications requiring precise flow control, globe valves are the better choice.

Q2: What is the difference between metal-seated and soft-seated globe valves?

ఎ: Metal-seated (metal-to-metal) globe valves withstand high temperatures (up to 425°C) and abrasive media, making them suitable for steam and high-temperature process applications. Soft-seated globe valves provide zero-leakage sealing but have a limited temperature range (typically ≤120°C), making them suitable for water and mild chemicals. This specific model features metal seating and is designed for high-temperature steam and oil & gas applications.

Q3: Can this globe valve be used for steam?

ఎ: అవును. This valve is designed specifically for steam applications and is rated for temperatures up to 425°C. The 13Cr hardened disc and graphite packing ensure reliable operation under steam service conditions. Please specify the steam application when ordering to confirm the correct configuration.

Q4: Is the installation direction of the globe valve important?

ఎ: అవును. Globe valves are typically installed according to flow direction; the medium should enter from beneath the disc (i.e., the flow pushes the disc upward to open). This helps protect the seating surfaces and utilizes the medium’s pressure to assist with sealing when closed. A flow direction arrow is usually marked on the valve body; please ensure installation follows this arrow.

Q5: What are the advantages of 13Cr hardening?

ఎ: 13Cr stainless steel hardening (hard-facing) provides excellent wear, erosion, and galling resistance, making it particularly suitable for high-velocity steam and process fluids. It significantly extends the valve’s service life under harsh operating conditions and reduces the frequency of maintenance and replacement.
