Description

The ANSI Cast Iron Non-Rising Stem Gate Valve is a robust isolation device designed for on/off flow control in systems where vertical clearance is a constraint. Constructed from durable ASTM A126 Class B cast iron with brass seating surfaces and flexible graphite packing, it meets rigorous North American standards for safety and performance, making it an essential component for buried or confined-space piping infrastructure.

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)

The ANSI Cast Iron Non-Rising Stem Gate Valve is a compact, robust isolation valve designed for industrial piping systems where vertical space is limited. Manufactured in accordance with MSS SP-70 and ANSI standards, it features a durable cast iron body (ASTM A126 Class B) and a non-rising stem mechanism. This design ensures the valve height remains constant during operation, making it ideal for underground installation or confined spaces.

Key Product Features:
  1. Compact Design: The non-rising stem configuration minimizes the overall height of the valve, suitable for installations with height restrictions.
  2. Low Flow Resistance: The full-bore, straight-through channel design ensures smooth fluid flow with a low flow resistance coefficient.
  3. Durable Sealing Surfaces: Sealing surfaces utilize high-quality materials (Bronze/Brass or Stainless Steel/Hard Alloy trim) to ensure a long service life and tight shut-off.
  4. Reliable Packing: Equipped with flexible graphite packing for reliable stem sealing, ensuring light and flexible operation with minimal leakage.
  5. Versatile Actuation: Available with manual handwheel, gear operators, electric, or pneumatic actuators to suit specific application needs.
  6. Structural Integrity: Features a rigid body design with high structural strength, available in elastic wedge, rigid wedge, or double gate configurations.
