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.

Our gate valves are cheap, but durable and reliable. We believe that our deep research and development and rich production experience are important reasons why we are trustworthy.

In the shut-off valve, the flow of water is controlled by a movable mandrel, and the flow of water is restricted by lowering the mandrel to a fixed valve seat.

Ball valves are often used for steam, water, oil, gas, air, and corrosive fluids. They can handle slurries and dusty dry fluids. The ball valve is not used for abrasive and fibrous materials, because it will damage the surface of the valve seat and valve

Wafer type is a common style of butterfly valve, which is cheaper than lug type. The wafer butterfly valve is installed between two flanges. The valve is held in place from flange to flange by using bolts or studs and nuts. Of course, this type of install

The plug or disc is an important part of the valve. It is connected to the valve stem and can be used for throttling.

Gate valves can be divided into two main types: parallel and wedge. The parallel gate valve uses a flat gate between two parallel valve seats. The popular type is a knife gate valve with sharp edges on the bottom of the gate.

Because of their spherical shape, these valves are called shut-off valves, and an internal baffle separates the two halves of the valve body. The moving part of the shut-off valve is composed of the valve disc, the valve stem and the hand wheel.

The gate valve is externally threaded and yoke type full bore, with elastic wedge and rising stem.

The pressure-sealed gate valve is designed in accordance with API 600, suitable for high temperature and high pressure working conditions, and is widely used in nuclear power plants and thermal power plants. Compared with bolted bonnet joint valves, they

Gate valves Gate valves are called rising valves or non-rising valves. Around the non-vertical stem gate valve, the stem is screwed into the gate around the lower end surface. Because the handwheel around the valve stem rotates, the gate will move the val

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 easy operation, maintenance and versatility of the ball valve make it widely used in industry. This high-quality ball valve will be an excellent choice for shut-off and control applications.

The ball valve is shaped like a bead. But the hole in the center is the same size as the pipe. It has gaskets on both sides of the flow, which can be completely closed. You can install it in any way. No matter which end you choose, one way to turn on the
