Z41Y Self-sealing Flanged Forged Steel Gate ValveOverview

Overview

The Z41Y self-sealing flanged forged steel gate valve is an outside screw and yoke (OS&Y) wedge gate valve manufactured with a forged steel body and flanged connections. Its body is formed through a forging process, resulting in a dense internal structure with mechanical properties superior to those of cast components. The valve is operated by a handwheel that drives the stem to lift or lower the wedge gate, achieving pipeline isolation. The sealing surfaces feature alloy steel hardfacing (designated by the model suffix "H"), forming a metal-to-metal hard seal. Specifically engineered for high-pressure, high-temperature, and critical service conditions, this valve offers enhanced strength, toughness, and reliability. It is an ideal choice for demanding pipelines in industries such as petroleum, chemical, and power generation. It is widely used as a critical isolation device in applications with stringent requirements for strength, sealing performance, and durability, including petrochemical units, oil refineries, power plant boiler feedwater systems, high-pressure steam lines, natural gas gathering and transmission pipelines, and high-temperature high-pressure process piping.

Z41Y Self-sealing Flanged Forged Steel Gate ValveCharacteristic

Features

1、Forged Steel Body, High Strength: The body is forged from high-quality forged steel (e.g., A105, F304, F316), resulting in a dense structure free from casting defects. It offers high mechanical strength and excellent impact resistance, making it suitable for high-pressure and cyclic operating conditions.

2、Outside Screw and Yoke (OS&Y), Visual Position Indication: The stem rises and falls with the gate. The valve opening position can be directly observed by the height of the stem extension, facilitating operation and maintenance.

3、Alloy Steel Hard Seal (Type "H"): The sealing surfaces of the disc and seat are overlaid with a hardfacing alloy (e.g., 13Cr, Stellite). This provides high hardness, wear resistance, erosion resistance, and high-temperature resistance, ensuring reliable sealing and a long service life.

4、Flanged Connection, Stable and Reliable: It utilizes standard flange connections (e.g., RF, RTJ), offering high connection strength, excellent sealing performance, and convenience for installation and disassembly.

5、Suitable for High-Pressure and High-Temperature Conditions: The overall structure and material selection make it suitable for high working pressures and temperatures, providing stable performance.

6、Full Bore Design, Low Flow Resistance: It features a full bore passage, resulting in low resistance to media flow and minimal pressure loss. This makes it ideal for systems with pressure drop requirements.
