Everything You Need to Learn about Gate Valves

Gate valves come with a shutoff and on mechanism. The gate is an internal device that opens up to allow media flow and then lowers to shut the valve. The most distinctive feature of the gate valve is that it has a straight path which minimizes pressure loss and permits simple cleaning. It also has less leakage because the flow of media is slow.

This article explains how the gate valve can be the ideal valve for certain situations. We’ll walk you through the parts, various kinds that are available, their pros and cons, and the aspects you need to take into consideration when purchasing the gate valve.

What exactly is the Gate Valve?

A gate valve can be described as a type of valve which can only shut and open. The gate valve has an opening as well as a closing plate inside the gate valve. If the handwheel is turned by the valve plate, it will move linearly either upwards or downwards, closing or opening, and allowing the fluid to flow or to be cut off.

Due to the fact of the valve’s gate design, which isn’t easily blocked it is perfect for the circulation of viscous substances like mud, like syrup garbage disposal, cement grease, and the like. It is used extensively in HVAC papers and pulp, sugar & Ethanol, cement plant and food industry, chemical industry, etc.

COVNA gate valves are able to customize different types of gate valves to suit your needs like lower temperature, higher temperature and high pressure, based on the needs of your various operational conditions. In addition, COVNA gate valve can be made from various materials that can be more suitable for your business.

COVNA as the leading Gate valve maker in China We are able to assist you in selecting the best gate valve that can give you better performance.

GATE VALVE ACTUATOR TYPES

As a one-stop valve actuator service supplier, COVNA also could offer actuators and valves for you to satisfy the various requirements. For making automation simpler.

Manuel Gate Valve(Manually Operated Gate Valve)

Manual gate valves are operated by hand valve that is operated by hand. By manually turning the handwheel the gate valve can be shut or opened and allows the fluid to circulate or stop. The gate valve manual provides an exact flow release or blocking feature that allows the worker to efficiently achieve their goal for flow management.

Automatic Gate Valve

If gates are outfitted with an actuator for gate valves that is automatic security and production effectiveness of the system will be significantly enhanced.

Automated gate valves are divided into electronic gate valves and pneumatic gate valves.

Electronic Gate Valve(Electrically Actuated Gate Valve)

Electric gate valve is the actuator of the gate valve is drives itself by DC/AC current and sends signals to open or close the valve. Because the opening and closing rate of the gate valve is slow the possibility of water hammering is significantly decreased. With technology and science, the desire for gate valves with electric motors is growing day by day.

Pneumatic Gate Valve(Air Operated Gate Valve)

Pneumatic gate valve refers to using compressed air in order to propel the actuator of the pneumatic gate valve to close or open the valve. Since it is a pneumatic valve that doesn’t require electricity to close or open it is both safe and secure.

GATE VALVE MODIFIES TYPES BY MATERIAL

COVNA produces gate valves in WCB or stainless steel that you can choose to meet your various needs. High-quality material that has passed the material test, is eco-friendly and safe for food use.

Stainless Steel Gate Valves

The gate valve made of stainless steel can be constructed of stainless steel 304 as well as stainless steel 316 and stainless steel 316L. Its distinctive durability and resistance to corrosion are highly regarded by many people who use it, which is why it is extensively employed.

This stainless steel that is used to make COVNA gate valve COVNA gate valve been tested by the material testing report and is 100% safe and usable.

Carbon Steel Gate Valves(WCB Gate Valves)

Carbon gate valves made of steel that process root technology is divided into gate valves made of forged steel and cast gate valves. The benefit of gate valves made from forged steel is that it can stand up to high pressure and is suitable for industrial heavy duty. The benefits of casting steel gate valve is that it can be made into a variety of kinds based on your needs.

GATE TYPES OF VALVES by connection

Flanged Gate Valves

Flanged gate valves have Flange connections on both ends. Gate valves that are flanged is the most frequently employed connection method used in industrial valves. Additionally ,the gate valve flange is also the most popular valve within COVNA.

Flanged gate valves use bolts and nuts to fix the pipe, making installation much easier.

Flanged gate valves are broken down in ANSI, JIS, DIN and GB standards based on the link standard in order to accommodate your needs for different working conditions.

GATE STEM VALVES

Rising Stem Gate Valve

A rising stem gate valve indicates that, when you rotate the handwheel, you will be able to clearly see the stem of the valve rising and falling in straight lines. If the medium is in circulation and the valve stem is in place, it will not be in contact with the medium. A rising stem gate valve can be installed using an actuator, ranging from an automatic gate valve or an automatic gate valve.

non-rising Stem Gate Valve

A non-rising stem gate valve happens when the handwheel is turned but are unable to be able to see the valve stem. As the medium circulates, the valve stem and valve plates will become exposed.

GATE VALVES TITLES BY SEAT

Metal Seated Gate Valves

The gate valve made of metal has an aluminum seat wedge which is mostly utilized to stop the flow of pipes or other equipment. It is extremely durable and has a longevity of service.

Resistant Seated Gate Valve

Resilient-seated gate valve is gate valves made of cast iron and has soft seals in order to decrease friction and increase the lifespan that the valve.

ADVANCEMENTS OF GATE VALVE

Gate valves are not simple to stop. It is also one of the most well-known valves across every industry. It is used in a variety of uses, including:

* Pulp and paper

* Treatment of wastewater

* Mining

* Power Plant

* Food, chemical, and beverage, oil , gas, etc.
