The gate valve cannot be opened and closed quickly. To fully open or close the wheel or gearbox actuator, the shaft should be rotated to the number of fully open revolutions. The number of full-open revolutions is equal to the pitch.

For non-vertical stem type valves, if the valve is opened, the stem will not move upward. The stem is screwed into the dish. When the handwheel on the valve stem rotates, the disc moves up or down along the valve stem on the thread, while the valve stem r

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

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 main difference between these two types is the way they are closed. The stop valve uses a plug (stem) that closes against the flow, while the ball valve has a gate (ball) that can close the entire flow. The stop valve is suitable for adjusting the flo

A stainless steel 3/4 ball valve is considered not only rugged and durable, but they also perform well after many cycles. In addition, the reliability of stainless steel mini ball valves is also worthy of attention, because they can be safely closed even

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

Gate valves are widely used in pipelines to transport media. Gate valves can be divided into wedge gate valves, flat gate valves, parallel double gate valves according to the form of valve seats. The product can have a longer service life. It can be insta

Compared with ball valves, gate valves require multiple turns to fully open. The valve is not suitable for throttling or control, because partial opening will cause damage to the gate and wear of the valve seat. In addition, some valve closures can cause

The gate valve is a two-way sealed valve. The valve body-bonnet joint and packing chamber are sealed with non-asbestos gaskets and packing to ensure a long service life.

The ball valve is designed to contain a ball in the valve. The ball valve is a form of quarter-turn valve that uses a hollow, perforated and rotating ball (called a "floating ball") to control the flow through it. It is open when the hole of the

The working principle of the stop valve is the vertical movement of the valve disc away from the valve seat. So when the valve is closed, it will cause the space between the disc and the seat ring to close. This is why these valves are used to start, stop

Wafer-type soft-seal butterfly valves use the flexibility of the rubber seat to easily achieve zero leakage, so they are widely used in oil fields, agriculture, water and wastewater, and mining industries. Because of its rubber-lined valve body material,

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
