The gate valve is the most common valve in the water supply system. It represents a linear motion isolation valve with the function of stopping or allowing flow. The gate valve is named after the closing element slides into the flow stream to provide clos

Simple structure, convenient operation, convenient installation, good sealing performance, long service life, high reliability, good interchangeability of parts, and cost saving.

High-performance stainless steel butterfly valves are one of the most widely used butterfly valve types in processed food-grade products. They are also used to treat corrosive fluids. Stainless steel butterfly valve adopts SS304, SS316 or SS316L body mate

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

The gate valve can provide different discs or wedges. The range of the gate valve is usually determined by the type of wedge used.

The valve seat of the gate valve is either provided integrally with the valve body or adopts a seat ring structure. The valve seat provided by the valve seat ring structure can be screwed into place or pressed into place and sealed and welded to the valve

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.

The valve seat of the gate valve is parallel to the flow direction of the medium, so there is less erosion of the valve seat when the valve is opened. This also makes the globe valve a good throttle valve. The disadvantage is that due to its design, there

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.

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

This is the connection from the actuator to the valve, which provides the driving force. The stem of the actuator control valve can be smooth, and the stem of the manual control valve can be threaded.

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