Products Description
Why Choose This Valve
The Forged Steel Flanged Gate Valve is a top choice for gas gate stations, main steam lines, and long-distance pipelines. These systems need full open or full close operations. They also have strict rules about flow resistance. When this valve is fully open, the flow path is straight. The resistance is almost zero. That makes it a great shut-off device.
Built Strong with Forged Steel
Chenxiang makes this valve from forged steel. The forging process creates a dense internal structure. It does not have the sand holes or porosity that cast steel often has. This gives the valve body strong pressure-bearing ability. The gate moves up and down. When it is open, the flow resistance is nearly the same as a straight pipe. This valve works in many fields. These include oil, chemical, natural gas, light industry, power,制药, metallurgy, water supply, and defense. It handles many media. These are compressed air, natural gas, coal gas, LPG, nitrogen, oxygen, hydrogen, steam, flue gas, and other process gases.
Key Models and Data
The models are Z41H, Z41Y, and Z41W. The body materials are forged steel A105 (carbon steel), F304/F316L (stainless steel), F22 (chrome-moly steel for high heat), and LCB (low temperature). The drives are manual, gear, pneumatic, electric, and hydraulic. The connections are RF, FM, and RTJ. The pressure range is PN16 to PN420 (150LB to 2500LB). The size range is DN15 to DN50 (1/2" to 2"). The working temperature is -29°C to 500°C.

Quality You Can Trust
The sealing face uses STL hard alloy overlay. This resists wear and erosion. It works well with fluids that have some particles or high speed. Every gate valve gets a shell strength test and an upper seal test before it leaves the factory. We use a submersible testing machine. The valve goes under water. We check for bubbles. That shows if the seals are tight. A direct-reading spectrometer checks the chemical makeup of the body material. This ensures the material meets the standards. Every valve comes with a material certificate and a pressure test report. These are traceable to the production batch. Chenxiang Valve has its own import and export license. We have shipped products to energy projects in the Middle East and Africa.
