Introduction of Electric Flat Gate Valve
A electric flat gate valve is a type of industrial valve used to control the flow of fluids, such as liquids or gases, within pipelines. It is named "flat" due to the flat or parallel gate that moves vertically to open and close the valve.
Our Related Products
When the valve is fully opened, the flow resistance coefficient is very small, and the valve will eliminate the function of the valve disc and the dirt on the sealing surface every time the valve is opened and closed.
Stainless Steel Flat Gate Valve
The packing is made of flexible graphite ring and graphite packing, reliable sealing, light and flexible operation.
The thrust bearing has large load capacity and the compound lip valve stem packing minimizes the switching torque.
It is widely used in oil and water steam pipelines such as petrochemical industry and thermal power plants to connect or cut off the intermediate quality of pipelines. The sealing surface of the opening and closing device has compact structure and reasonable design.
Gray Cast Iron Flat Gate Valve
The cast iron gate valve, furnished with cast gray iron or ductile iron body and bonnet, is a linear-motion manual valve that uses a typically flat closure element perpendicular to the process flow, which slides into the flow stream to provide shutoff.
Ductile iron gate valve is appropriate for fitting between PN16 flanges, intended for general, industrial and HVAC applications; warm and cold water heating systems where a narrow shutdown is necessary.
Titanium Alloy Flat Gate Valve
Titanium and titanium alloys are non-ferrous high chemical activity metals. Titanium materials have oxide films, good stability and self-passivation ability in strong corrosion environment, so titanium valves can resistance a variety of harsh corrosion conditions.
Nickel Alloy Valves have high amounts of nickel. Nickel, as a corrosion resistant element, provides the material with high corrosion resistance; especially against acids. So the nickel alloy valves are used in chemical and petrochemical industries much.
Suitable for natural gas, petroleum, chemical, gas pipelines and other transmission lines, vent systems and steam storage devices, used as opening and closing equipment. Long haul pipeline for natural gas extraction and purification.

Structural Features of Electrical Flat Gate Valve
This series of products adopt the new floating seal structure, which is suitable for the opening, closing and adjusting devices of control media such as oil and natural gas with pressure less than 15.0MPa and temperature from -29 ℃ to 121 ℃. The product is of novel design, Proper, rigorous testing, light operation, with strong corrosion resistance, wear resistance, erosion resistance, the oil industry is an ideal new equipment.
Using floating seat, two-way opening and closing, reliable sealing, opening and closing flexible.
The gate has a guide to give precision guidance, while the sealing surface are sprayed carbide, erosion-resistant.
Body bearing capacity is high, the channel is straight-through, fully open, and the gate diversion hole through and straight pipe similar to the flow resistance is very small. Stem composite filler, multiple seals, making the seal reliable, small friction.
Close the valve, turn the handwheel clockwise, the gate moved down to the bottom, due to the role of medium pressure, the inlet seal seat toward the gate direction, the formation of a larger seal than the pressure, forming the first seal . At the same time, the gate pressure to the outlet seal seat, a double seal.
Due to the double seal, the consumable parts can be replaced without affecting the pipework. This is our factory product priority over similar products at home and abroad an important feature.
Open the gate, turn the hand wheel counterclockwise, the gate moved up, diversion hole and channel hole through. With the rise of the gate, the through hole gradually increases to the limit position, the guide hole coincides with the passage hole, then fully open.
Benefits of Electric Flat Gate Valve

The Maintenance Methods for Electric Flat Gate Valve
Use Silicone Tape
When we are dealing with a steel gate valve in the home, in fact, we are dealing with plumbing issues. Sometimes it becomes necessary to shut off the water in the home because of the plumbing work or the broken pipe. Where the steel gate valve is installed actually has a weakness as it exists between two pipes that screw into either end of the valve. These areas are weak points when pipes are blocked or frozen. To maintain this connection we should wrap the threads with silicone tape and replace every year.
Use Lubrication
As time goes by, the steel gate valve will start to get stuck. To prevent the valve from sticking we need to periodically lubricate the stem of the valve wheel. Any type of spray lubricant can do the work. In winter, it is better to lubricate the wheel and stem once at the beginning of a month and once at the end of a month.
Be Wary of Rust
Rust is always a problem on a steel gate valve and especially one that is outside of the home. We should inspect the valve regularly for rust. If there is some rust, we can use a wire brush to scrape the rust off of the metal. It is also a great idea to paint the steel gate valve in order to prevent rust. We need to remove the rust before painting it because the rust can continue to spread.
Use the Valve
A good way to keep these valves working efficiently is to use them. All we need to do is turn the knob to the left to close the valve and then to the right to open the valve. Doing this occasionally will prevent the valve from sticking inside the pipe as well as keeping the wheel loose.
Tighten the Nuts
The steel gate valve is assembled with a series of nuts which attach the valve to the pipes and the wheel knob to the stem. Use an adjustable wrench to tighten all nuts to the right every year or so, which is good for valve pressure maintenance.
