Cast Steel ANSI Gate Valve

Cast Steel ANSI Gate Valve

Kunjian Tech’s Cast Steel ANSI Gate Valves are engineered for heavy-duty industrial applications requiring reliable shut-off and minimal pressure drop. Designed and manufactured in strict accordance with API 600 and ASME B16.34 standards, these valves offer superior performance in high-pressure and high-temperature environments, including oil and gas, petrochemical, and power generation sectors.

Key Technical Features:

• Fully compliant with API 600 (Design), ASME B16.10 (Face-to-Face), and ASME B16.5 (Flange Dimensions).
• Features a Bolted Bonnet (BB) and Outside Screw and Yoke (OS&Y) design for easy maintenance and visible stem positioning.
• Hardfaced, ground, and lapped seat faces ensure a mirror finish for bubble-tight sealing and extended service life.
• The one-piece flexible wedge compensates for seat face distortions and thermal expansion, preventing the valve from sticking in the closed position.
• Standard bodies are cast from ASTM A216 WCB carbon steel, with 13% Cr trim for excellent wear and corrosion resistance.

Specifications:

• Size Range: 2” to 48” (DN50 – DN1200)
• Pressure Ratings: ANSI Class 150, 300, 600, 900, 1500, and 2500
• End Connections: Raised Face (RF), Ring Type Joint (RTJ), and Butt Weld (BW)
• Temperature Range: -29°C to 425°C (standard carbon steel)
