Flange Gate Valve | Durable Cast Iron & Stainless Steel Gate Valves for Industrial Use

Z41W ANSI ASME API600 Rising Stem CF8M Stainless Steel Handwheel Flange Gate Valve

Z41W ANSI ASME API600 Rising Stem CF8M Stainless Steel Handwheel Flange Gate Valve Metal Seated Gate Valve for WOG OS&Y

Product Feature

Our Flange Gate Valve is engineered for dependable performance in demanding industrial pipelines. Key features include:

Robust Construction: Manufactured from high-grade ductile iron for superior strength and longevity, ensuring reliability under high pressure.
OS&Y Design (Outside Stem & Yoke): The rising stem provides a clear visual indicator of the valve's open or closed position, enhancing operational safety.
Metal Seated Seal: Features a sturdy metal-to-metal seal (Z41W design), offering excellent resistance to wear and high temperatures, making it ideal for a variety of media.
Flange End Connection: Ensures a strong, leak-proof connection to piping systems, compliant with international standards for easy installation and compatibility.
Handwheel Operation: Manual operation provides precise control over flow, simple to use and maintain without requiring external power sources.

Product Description

A gate valve is a fundamental component for isolating flow in a pipeline. The valve plate (gate) moves vertically to the direction of flow, providing a tight seal when fully closed. Our Flange Gate Valves are designed to meet rigorous standards like ANSI, ASME, and API600, guaranteeing their performance in general water services, industrial applications, and various oil and gas equipment sectors. They are the preferred choice for mainline isolation where a straight-line flow and minimal pressure drop are crucial.
