Key Features

ASTM A105 Forged Steel Construction

The forged steel body provides excellent mechanical strength, pressure resistance, and durability for demanding industrial applications.

Class 800 High-Pressure Design

Designed to operate safely and reliably in high-pressure systems commonly found in oil & gas, petrochemical, power generation, and industrial processing facilities.

Full Stellite Hard-Faced Trim

The wedge and seat sealing surfaces are hard-faced with Stellite alloy, providing superior resistance to wear, erosion, and thermal stress while extending valve service life.

Full Bore Flow Path

The gate valve is designed for full open or full close operation, allowing maximum flow capacity with minimal flow restriction.

Low Pressure Drop

When fully opened, the straight-through flow path minimizes pressure loss and improves overall system efficiency.

Secure Socket Weld Connection

The SW connection provides a strong and leak-tight joint, making it ideal for high-pressure and high-temperature applications.
