In the 19th century, due to the increasing use of gate valves in industrial operations, their intensive development moved forward rapidly. Over time, the materials involved in manufacturing have been improved and modified to suit different applications.

The three-piece ball valve uses the same dynamic multi-ring gland system as the needle valve to provide higher strength and integrity. When combined with the blowout prevention rear seat valve stem, it can ensure that it can withstand all operating proces

Concentric design wafer butterfly valve, with no back structure, rubber welded valve body, replaceable elastic seat, streamlined disc, integrated stem

Electric actuator ball valves have full-diameter models, some are cavity-filled, and some are V-shaped ball valves. Designed for throttling or switching applications in a variety of industries, including pulp and paper, chemical, power, oil and gas, and m

The gate valve allows the user to control the flow pressure instead of simply closing or opening it. Compared with ball valves, gate valves provide users with more control over water flow and pressure, but they cannot let users choose to stop the water fl

The gate valve has a closing/closing mechanism. There is an upward internal gate device that allows the medium to flow and closes the valve downward. A distinctive feature of the gate valve is its straight passage, which reduces pressure loss and is easy

In a system with irregular changes in high temperature, the gate valve will leak due to the load in the valve end pipe.

The valve cage is a part of the valve, which surrounds the valve plug and is located in the valve body. The valve cage is the main component that determines the fluid flow in the valve. As the stopper moves, more cage openings are exposed and the flow rat

The structure of the wafer butterfly valve is formed by the central disc rotating 90 degrees in the valve body. Using the drive type, the flow of fluid can be stopped, adjusted or started. In the wafer connection, the valve is installed between pipe flang

The stop valve is a linear motion valve, which can be used to start and stop and adjust the fluid flow. The stop valve is mainly used for throttling service and automatic control.

Types of butterfly valves: lug type butterfly valve, U-shaped flange butterfly valve, double flange butterfly valve, fluorine-lined PTFE butterfly valve, double eccentric butterfly valve and triple eccentric butterfly valve

The pipeline gate valve is designed to meet the long-distance transportation service of crude oil and natural gas. It is designed in accordance with API 6D and has DBB function, so the valve can provide two-way switching services. Our straight-through con

Generally, gate valves are used to completely close the fluid flow in the pipeline, or to provide the full flow in the pipeline when fully opened. Therefore, it can be used in a fully closed or fully open position.

Do not use the valve as a crowbar to open the flange, as this may cause damage to the flange area and/or damage to the O-ring seal.

The ball valve is durable, performs well after many cycles, and is reliable, and can be safely closed even after long periods of non-use. These qualities make them an excellent choice for shut-off applications where they are generally more popular than ga
