Expanding Gate Valve

As an expanding gate valve manufacturer,  takes pride in offering the highest quality expanding gate valves on the market. An expanding gate valve is a type of gate valve that is designed with a gate that expands when it is closed. This unique feature makes expanding gate valves ideal for use in applications where tight shut-off is critical, such as in the oil and gas industry.

are one of the most commonly used valves in industrial applications. They are designed to regulate the flow of fluids by using a gate that slides up and down to open or close the valve. While traditional gate valves can experience issues with leaking, expanding gate valves use a wedge-shaped gate that expands to create a tight seal against the valve body. This design provides reliable and efficient shut-off in high-pressure and high-temperature applications.

Toparts Valve Co., Ltd. offers a wide range of expanding gate valves that are available in a variety of sizes, pressure ratings, and materials. Our valves are made from high-quality materials such as carbon steel, stainless steel, and alloy steel, ensuring durability and long-term performance. We also offer customization services to meet the specific needs of our customers.

In addition to manufacturing expanding gate valves, provides comprehensive technical support and after-sales service to ensure the optimal performance of our valves. We work closely with our customers to ensure that they receive the best possible solution for their application.

At Toparts Valve Co., Ltd., we are committed to providing the highest quality expanding gate valves on the market. Our expertise, technical knowledge, and dedication to customer satisfaction make us a trusted partner for customers looking for reliable and efficient valve solutions. You are welcome to !

Main Features

Expanding gate valve is an efficient and reliable through-conduit gate valve, with two floating seats and parallel expanding gate and segment. The expansion action between gate and segment provides a tight mechanical seal on both upstream and downstream. Full bore through conduit design can eliminate flow turbulence. Pressure drop is no larger than through an equal length of pipe.

Design standard: API 6D

4. Non-rising stem design can be chosen;

5. Spring loaded packing can be chosen;

6. Low emission packing can be chosen according to ISO 15848 requirements;

7. Extended Stem design can be chosen;

8. Normally open type or normally close type with Through conduit design.

Application

Expanding gate valves have a wide range of applications across many industries, especially in the oil and gas industry. These valves are designed to provide reliable shut-off in high-pressure and high-temperature applications. Some common applications of expanding gate valves include:

1. Oil and Gas Industry: Expanding gate valves are commonly used in the oil and gas industry for the regulation of fluid flow in pipelines, refineries, and offshore platforms. These valves are ideal for use in critical applications such as wellheads, gas injection systems, and production pipelines.

2. Petrochemical Industry: In the petrochemical industry, expanding gate valves are used for regulating the flow of chemicals and other fluids. They are suitable for use in applications that involve highly corrosive or abrasive fluids.

3. Power Generation Industry: Expanding gate valves are also used in power generation plants for regulating the flow of steam and other fluids. These valves are ideal for use in high-temperature and high-pressure applications.

4. Water Treatment Industry: Expanding gate valves are used in water treatment plants for regulating the flow of water and other fluids. These valves are ideal for use in applications that involve high-flow rates and high-pressure.

5. Mining Industry: Expanding gate valves are used in the mining industry for the regulation of the flow of slurries and other fluids. These valves are ideal for use in applications that involve highly abrasive and corrosive fluids.

Overall, expanding gate valves are a reliable and efficient valve solution for applications that require tight shut-off and long-term performance in high-pressure and high-temperature conditions.
