Bronze valves originally referred to copper-tin alloy valves. Later, copper alloys other than brass and cupronickel were called bronze, and the name of the bronze valve was often prefixed with the name of the main added element. The Aluminum bronze integral forged flange gate valve has high strength, good wear resistance and corrosion resistance. It is used to cast high-load gears, shaft sleeves, and marine propellers.

Stainless steel welded flange gate valve, flange connection is suitable for cutting or connecting the pipelines of various petroleum, chemical, hydraulic, and electric power stations with a nominal pressure of PN1.6 ~ 16.0MPa and a working temperature of -29°C ~ 550°C. Pass the pipeline medium. Applicable media are: water, oil, steam, acid, alkali, ammonia, urea, sulfur-containing natural gas, etc.

Aluminum bronze threaded gate valves are used as replacement for many Monel, duplex and super duplex grade valves. These are used mostly in sea water, salt water, brackish water and highly corrosive applications. The valves are cheaper compared to the other higher alloys. Larger diameter valves are available in different aluminum bronze grades. Aluminum bronze threaded gate valves use a gate to operate the valve. The gate opens or closes the valve and is connected to the valve stem. The valve stem is fitted with a handle which moves the stem in up or down and the gate opens and closes the valve.

It cannot be used as a control valve. The 316 Stainless Steel Gate Valve is used in sour water services to open and close operations. The twisting of the threaded stem inserts the gate slowly and prevents the water hammer effect on the gate as well. The gate valve can be designed as clockwise opening or counterclockwise opening or closing. This depends on the basis of the application. As a leading manufacturer, we produce the valves in different types, sizes and capacities. The input and output sizes, the valve strength, the allowable maximum pressure and the thread size and gates sizes differ for different types as the Stainless Steel sluice valve

Cast steel flange gate valve, the full name is "flange connection API cast steel gate valve", suitable for ANSI Class 150 ~ 2500, working temperature <600 ℃ on the pipeline of various working conditions such as petroleum, chemical industry, thermal power station, etc. Pass the pipeline medium. Applicable media are: water, oil, steam, etc. The operation modes are: manual, gear drive, electric, pneumatic, etc.

he most obvious advantage of SS self-sealing socket welded gate valve is: In the process of opening and closing, the friction between the disc and the sealing surface of the valve body is smaller than that of the gate valve, so it is wear-resistant. The opening height is generally only 1/4 of the diameter of the valve seat passage, so it is much smaller than the gate valve. Usually there is only one sealing surface on the valve body and the valve flap, so the manufacturing process is better and it is easy to maintain.

What is a duplex stainless steel gate valve The duplex stainless steel gate valve is a device for separating and merging or switching flow direction, made of duplex stainless steel. This type of valve is mainly used for fluid transportation, cutting off, and circulation, with functions such as shut-off, diversion, pressure stabilization, and diversion. The gate of the duplex stainless steel gate valve moves linearly with the valve stem, and its opening and closing component is the gate. The direction of the gate's movement is perpendicular to the direction of the fluid. This design allows the gate valve to only perform fully open and fully closed operations, and cannot be adjusted or throttled. The gate of a duplex stainless steel gate valve has two sealing surfaces, and the most commonly used mode is that the two sealing surfaces of the gate valve form a wedge shape. The wedge angle varies with the valve parameters, usually 50 °, and 2 ° 52 'when the medium temperature is not high. The gate of a wedge gate valve can be made as a whole, called a rigid gate; It can also be made into a gate that can produce slight deformation to improve its processability and compensate for the deviation of the sealing surface angle during the processing. This type of gate is called an elastic gate。
