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

The sealing ring adopts seatback type, mortise type or directly vulcanized on the valve body. The sealing surface of the valve seat flange adopts an O-ring to cooperate with the pipe flange cone, and the sealing effect is good. It is easy to disassemble a

The three-way ball valve is made of stainless steel and can withstand a working pressure of 1000 PSI. The available ports are L-Port or T-Port. The ball valve is connected at the threaded end: BSPP or NPT.

Ball valve is a form of right-angle rotary valve, which uses a hollow, perforated and rotating ball to control it. It is open when the hole of the ball is aligned with the hole of the ball, and it is closed when it is rotated 90 degrees by the valve handl

The gate valve is a valve that completely restricts the flow of fluid and provides a full-diameter valve without changing the direction. The valve disc is appropriately called a gate here and is moved into the fluid at right angles by a threaded shaft wor

Gate valves are very reliable in shutting off the water supply. They are usually used as shut-off valves for the main water supply line and branch water supply lines, although ball valves are gradually becoming more and more popular in these applications.

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.

If the flow, volume and pressure can be adjusted frequently, the stop valve can be used as a control valve. The design of the shut-off valve makes it very suitable for flow regulation and start and stop flow.

Its working principle is to lift or press a rectangular or circular gate connected by the valve stem to the fluid path by rotating the handle wheel clockwise and counterclockwise.

Because of its ability to cut off liquids, gate valves are often used in the petroleum industry. For extremely viscous fluids, special valves commonly called knife valves are used to cut off the liquid. A typical gate valve is designed to be fully open or

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

Ball valves and plug valves are very similar in basic functions and applications. Both are control valves used to provide tight shutoff in different types of piping units. They also work on the same basic principle, that is, using a porous disk to start o

The main difference between ball valves and globe valves is the way they close. A ball valve has a stem and a ball, which rotate horizontally and are usually called "rotary" valves. The globe valve has a stem and a plug, which stroke linearly, a

We test every valve during the production process, and carry out quality control in all processes such as forging, processing, and assembly to ensure quality.

The manual gate valve is operated by a simple handwheel to raise the valve stem and gate. When closed, the gate rests on a seat ring, both of which are specially treated to provide a reliable closure.
