The gate valve is a key element of the pipeline system,
used in the petrochemical industry to control the flow of liquids and gases.
The peculiarity of this fitting is the use of wedge locking element, which ensures tight closure and reliable shut-off of the flow.
Gate valves are easy to operate and maintain, making them a popular choice in the industry.
