Z41H Forged Steel Flanged Gate ValveOverview

Overview

Z41H forged steel flange gate valve is a rising stem wedge gate valve manufactured with forged steel valve body and flange connection. The valve body is formed through forging process, with a dense internal structure and better mechanical properties than castings. The valve is driven by a handwheel to lift and lower the valve stem, which in turn drives the wedge gate to open and close the pipeline. The sealing surface adopts alloy steel overlay welding ("H" type) to form a metal hard seal. This valve is designed specifically for high pressure, high temperature, and critical working conditions, with higher strength, toughness, and reliability, making it an ideal choice for demanding pipelines in industries such as petroleum, chemical, and power. Widely used in petrochemical plants, refineries, power plant boiler feedwater systems, high-pressure steam pipelines, natural gas gathering and transportation pipelines, and high-temperature and high-pressure process pipelines with strict requirements for valve strength, sealing, and durability, as a key cutoff equipment.

Z41H Forged Steel Flanged Gate ValveCharacteristic

Characteristic

1. Forged steel valve body, high strength

The valve body is forged from high-quality forged steel (such as A105, F304, F316), with a dense structure, no casting defects, high mechanical strength, and good impact resistance, suitable for high pressure and fatigue conditions.

2. Clear stem structure, intuitive valve position

The valve stem rises and falls with the gate, and the valve opening can be directly determined by observing the height of the valve stem extension, which is convenient for operation and maintenance.

3. Alloy steel hard seal ("H" type)

The sealing surface of the valve disc and seat is welded with hard alloy (such as 13Cr, Stellite), which has high hardness, wear resistance, erosion resistance, high temperature resistance, reliable sealing, and long service life.

4. Flange connection, stable and reliable

Using standard flange connections (such as RF, RTJ), the connection strength is high, the sealing performance is good, and it is easy to install and disassemble.

5. Suitable for high temperature and high pressure working conditions

The overall structure and material selection make it suitable for higher working pressures (such as PN16-PN100) and temperatures (-29 ℃~425 ℃), with stable performance.

6 full bore design, low flow resistance

Adopting a full bore flow channel, the medium has low flow resistance and pressure loss, making it suitable for systems with pressure drop requirements
