This is a American standard flanged gate valve. It is an industrial pipeline active on/off control device. The material is WCB carbon steel (suitable for normal temperature/medium pressure conditions). The core function of the American Standard (ASME) flange gate valve is to manually control the on/off of pipeline media (water, oil, gas, etc.). It is commonly used in industrial systems such as petroleum, chemical, and municipal industries.

Advantages
Features
ASME Compatibility
Specifications (diameter, pressure, material) conform to ASME standards and are compatible with ASME piping systems;
Rising Stem Structure
The valve stem rises and falls with the opening and closing action, allowing for direct indication of valve opening;
Flange Connection
Flanges at both ends facilitate easy assembly and disassembly, ensuring reliable sealing.
Application Scenarios
These ASME (American Standard) flanged rising stem gate valves are designed for use in conventional medium-pressure industrial/municipal pipeline systems, based on their material and pressure rating. Key application scenarios include:
1. Industrial Sector:
* Petrochemical: On/off control of light oil pipelines and chemical raw material (non-corrosive) pipelines in oil refineries;
* Power Energy: Cooling water and auxiliary steam (≤425℃) pipelines in thermal power plants;
* Metallurgical Manufacturing: Circulating water and compressed air pipelines in steel plants.
2. Municipal/Civilian Sector:
* Urban Water Supply: On/off control of main municipal water supply pipes and secondary water supply pumping stations;
* Central Heating: On/off control of urban heating hot water (≤150℃) pipelines.
3.General Scenarios:
Used as a core on/off valve in various medium-pressure (≤2.0MPa), normal/medium-temperature (≤425℃), non-corrosive media pipeline systems.
Production Process
Raw material processing
WCB carbon steel is cast into valve body blanks, and key parts such as flanges and sealing surfaces are precision machined;
Component assembly
Components such as gate, valve stem, and packing are installed, and the handwheel drive mechanism is assembled;
Pressure testing
The valve body undergoes water/air pressure testing to verify sealing performance;
Surface treatment
Rust-proof painting (carbon steel), marking, and final packaging for shipment.
Routine maintenance
Regular lubrication: Regularly lubricate the connection between the handwheel and valve stem to ensure smooth operation;
Sealing inspection: Check the sealing of the flange gasket and packing every 3-6 months, and replace them promptly if they show signs of aging;
Avoid excessive force during operation: Avoid forcibly turning the handwheel when opening or closing to prevent valve stem deformation or gate jamming.
Feedback
The "Good quality" that customers recognize at first glance goes beyond just appearance-for their chemical pipelines, it means the valve body won't corrode due to material impurities, the sealing surface won't leak due to insufficient precision, and subsequent installation and maintenance costs will be significantly reduced. Our valves deliver "long-term peace of mind" with their "good quality at first glance."
Packaging & Transportation
Transportation: We ship goods by UPS/DHL/FEDEX express which takes 3- 5 days to arrive, or by air cargo which takes about one week to arrive , or by sea which takes about one month to arrive , depending on your actual requirements.
