GOST/Russian Carbon Steel Gate Valve

Description

The WCB Carbon Steel Gate Valve is a heavy-duty industrial valve designed for reliable isolation in high-pressure and high-temperature piping systems. Constructed from ASTM A216 WCB cast steel, this valve offers superior mechanical strength and thermal resistance compared to cast iron alternatives. It features a rising stem design (Outside Screw & Yoke) for clear visual position indication and is engineered to meet GB/T standards, making it a suitable equivalent for GOST/Russian market requirements.

Technical Specifications:

• Nominal Pressure (PN): 1.6 MPa (PN16)
• Nominal Diameter (DN): DN50 – DN300 (Standard Range)
• Applicable Medium: Water, Steam, Oil, Gas
• Operating Temperature: -29°C to 425°C (Carbon Steel Range)

Main Parts and Materials:

Key Features:

• High Strength Body: WCB cast steel construction ensures durability under high pressure and thermal stress.
• Wear-Resistant Trim: The seat ring utilizes Aluminum Bronze (2CuAl10Fe3), providing excellent resistance to wear and galling, ensuring a tight seal over long cycles.
• Reliable Sealing: Graphite packing and spiral wound-style gaskets (1Cr13+Graphite) ensure leak-tight performance even at elevated temperatures.
• Rising Stem Design: The OS&Y (Outside Screw & Yoke) mechanism allows operators to visually verify valve status (open/closed) from a distance.
