ANSI Cast Iron Rising Stem Gate Valve

Description

The ANSI Cast Iron Rising Stem Gate Valve is a robust isolation valve designed for industrial piping systems. Manufactured in accordance with MSS SP-70 and ANSI standards, it features a durable cast iron body (ASTM A126 Class B) and a rising stem mechanism (Outside Screw & Yoke). This design provides clear visual indication of the valve’s open or closed status, making it ideal for above-ground installations where operational visibility is required.

Technical Specifications:

• Nominal Size (NPS): 2″ – 24″ (DN50 – DN600)
• Pressure Rating: Class 125 / Class 250
• Applicable Medium: Water, Oil, Gas, and Non-Corrosive Fluids
• Suitable Temperature: -29°C to 200°C (-20°F to 400°F)

Main Parts and Materials:

Key Product Features:

1. Low Fluid Resistance: The internal structure of the valve body is straight-through, allowing the medium to pass unimpeded with minimal pressure drop.
2. Efficient Operation: The motion direction of the gate is perpendicular to the flow direction of the medium, enabling fast opening and closing speeds with reduced operating torque.
3. Visual Position Indication: The rising stem design allows operators to easily verify the valve status (open or closed) from a distance.
4. Durable Sealing: Features brass seat rings and flexible graphite packing for reliable, long-lasting sealing performance.
