Thread Gate Valve

Product Introduction

‌Thread gate valves are a common type of valve, the main feature of which is internal or external threads on the valve body, and are usually used for threaded connections with pipes in low-pressure projects.‌ The closing principle of the thread gate valve is to make the sealing surface of the valve clack and the sealing surface of the valve seat closely fit through the pressure of the valve stem, thereby preventing the flow of medium. The opening and closing part is a plug-shaped valve clack, the sealing surface can be a flat surface or a conical surface, and the valve falp moves straight along the center line of the fluid‌.

Product Advantages

1. The structure of the thread gate valve includes main components such as valve body, valve cover, valve stem, and valve disc. There are two types of stem movement: lifting stem and lifting rotating stem. The lifting valve stem lifts and lowers, but the handwheel does not lift; The lifting rotary stem has that hand wheel rotate together with the valve stem, and the nut is arranged on the valve body‌‌.

2. Because it adopts internal thread connection, the installation process is relatively simple and fast‌.

3. The thread gate valve adopts precise internal thread design and high-quality materials to ensure the good sealing performance of the valve when it is closed.

4. Thread gate valves mainly include internal thread gate valves, external thread gate valves, imported internal thread gate valves, stainless steel thread gate valves, and copper gate valves.

• Design Standard: ASME B16.34

• Threaded End: NPT / BSPT / RC / G

• Inspection and Testing: API598

• Thread gate valves are suitable for medium-and-low pressure environments and are often used in occasions that require frequent opening and closing. Because of its simple structure and convenient operation, it is widely used in water supply and drainage, heating and ventilation, fire protection and other systems‌.

• In order to ensure the normal operation of the thread gate valve and extend its service life, it is recommended to regularly check the sealing performance of the valve to keep the valve clean and prevent impurities from entering. At the same time, care should be taken to prevent excessive impact during opening and closing of the valve to reduce wear and tear‌.

• The medium channel inside the thread gate valve body is straight, the medium flows straight, and the flow resistance is small‌. 

• The opening and closing time of thread gate valve is only 1/6 of that of traditional products, which is fast and time-saving to operate‌.
