4 brass gate valve
The 4 brass gate valve is a type of gate valve with a nominal diameter of 4 inches and brass as its main material. It is a valve that lifts or lowers the gate (valve core) by rotating the hand wheel, thereby fully opening or completely cutting off the flow of medium in the pipeline

Structure and Advantages
Structural Forms
Rising Stem brass Gate Valve
The valve stem rises and falls synchronously with the gate, allowing intuitive judgment of the valve opening status, suitable for ground or scenes with sufficient operating space.
Non-rising Stem brass Gate Valve
The valve stem rotates in place, and the gate rises and falls in the valve body, with a small installation height, suitable for underground pipelines or limited space.
Product Advantages
Strong Corrosion Resistance
Brass material has good tolerance to water, seawater and non-oxidizing fluids, ensuring clean water quality and prolonging service life.
Minimum Flow Resistance
When the valve is fully open, the medium channel is straight, reducing energy consumption of fluid transportation.
Good Processing Performance
Brass is easy to cast and machine, the valve castings are smooth without sand holes, and the handwheel rotates smoothly.
Good Sealing Effect
Adopting soft sealing design, effectively preventing medium leakage and improving system tightness.
Applicable Scenarios
Building Water Supply and Drainage System:Used as the main pipeline cut-off valve to control the overall water flow.
Fire Pipeline System:Installed on the inlet and outlet pipes of fire pumps and zoned water supply main pipes, used as control valves to ensure fire water supply.
HVAC System:Suitable for HVAC water systems in large buildings to regulate the transportation of hot and cold media.
Industrial Pipes:Used in industrial pipelines for transporting non-strongly corrosive media such as water, oil and gas to achieve precise medium control.
Purchasing Tips
Confirm Caliber and Thread
Measure the outer diameter of the pipeline or the size of the existing valve, confirm it is 4 inches (DN100), and confirm the thread type (such as G thread, NPT thread) to ensure matching.
Check Pressure Rating
Check the valve mark (such as PN16, PN25 or Class 150) to ensure it meets the working pressure requirements of the pipeline system.
Match the Medium Used
According to the actual conveying medium (water, oil, gas, etc.) and temperature range, confirm whether the brass material is applicable.
Consider Installation Space
Choose rising stem gate valve for sufficient space, and non-rising stem gate valve for limited space to ensure convenient installation and operation.
Choose High-Quality Brands
Prioritize brands with good reputation, check the valve appearance and operation feel, and ensure product quality.
Our 4 brass gate valve is made of high-quality H59-1 and H62 brass, featuring excellent corrosion resistance, suitable for non-corrosive media such as tap water, hot water, and edible oil. With a nominal pressure of 1.6 MPa and a temperature range of -20℃ to 120℃, it handles harsh working conditions easily.
