Stainless steel threaded gate valve
Stainless steel threaded gate 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

Aluminum bronze threaded gate valve
Aluminum bronze threaded gate valve
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.

SS self-sealing socket welded gate valve
SS self-sealing socket welded gate valve
The 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.

Cast steel flange gate valve
Cast steel flange gate 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.

Aluminum bronze integral forged flange gate valve
Aluminum bronze integral forged flange gate valve
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 self-sealing welded globe valve
Stainless steel self-sealing welded globe valve
Stainless steel self-sealing welded globe valve refers to a valve whose closing part (disc) moves along the center line of the valve seat. According to this movement form of the disc, the change of the valve seat port is proportional to the stroke of the disc; the forged steel cut-off valve is It is widely used in water conservancy industry. As the basic control equipment of industrial piping system, its role is very important.

Stainless steel manual welding flange angle globe valve
Stainless steel manual welding flange angle globe valve
Stainless steel manual welding flange angle globe valves are a type of globe valves that are used in varying angles to the pipeline. Most valves are used in perpendicular to the pipe system. The globe valves have a valve body within which a plug is raised and lowered to close and open and opening inside the body structure. The Stainless steel manual welding flange angle globe valve was designed in a globe shape in the early times. Nowadays, there are different shapes of valves that are called the globe valves. The angle of the valve is decided as per the application need. The angles allow the applications to reduce the coefficient of the flow than in usual patterned valves. The Angle Globe Control Valve is used to regulate the flow of the liquid rather than completely stopping and allowing the fluid flow.

Integral flange self-sealing globe valve
Integral flange self-sealing globe valve
Integral flange self-sealing globe valve is designed and manufactured in strict accordance with API602, BS 5352 standards. The valve disc is positioned along the center for lifting movement (the bushing is made of a special material with good wear resistance and a small friction coefficient), flexible and reliable, excellent sealing performance. Integral flange self-sealing globe valves are widely used in pipelines in the petroleum, chemical, pharmaceutical, and electric power industries.

Stainless steel socket welding globe valve
Stainless steel socket welding globe valve
Our Stainless steel socket welding globe valve can be used to throttle flow control. Shut off is accomplished by moving the disc against the flow stream rather than across it as in the case with a gate valve. The flow pattern through a globe valve involves changes in direction, resulting in greater resistance to flow, causing high-pressure drop. The globe valve is an excellent valve to use in high-pressure operation of steam. Our Stainless steel socket welding globe valves are factory-made with quality material for long-term use.

Stainless steel forged oxygen globe valve
Stainless steel forged oxygen globe valve
The Stainless steel forged oxygen globe valve is a mandatory sealing valve. When the medium enters from below the valve disc, the resistance that the operating force needs to overcome is the friction force of the valve stem and the packing and the thrust generated by the pressure of the medium. The force of closing the valve is greater than the force of opening the valve, so the force of the valve stem The diameter should be large, otherwise the valve stem will bend up failure.
