Gate valves

As a distributor of industrial valves with many years of experience, we offer a wide range of industrial gate valves used across numerous sectors, including oil & gas, chemical, pulp and paper, food processing, as well as water & wastewater and power generation installations.
 The industrial gate valves we supply meet the highest technical requirements, ensuring reliable operation, long service life, and complete tightness even under high pressure and high-temperature operating conditions.

Gate valves available in the Flow Valves portfolio can be equipped with manual actuators (handwheel, gearbox), hydraulic actuators, or electric actuators – in standard versions or with various types of communication modules.
 Thanks to a wide range of materials and connection configurations (flanged, wafer, threaded, or welded), our industrial gate valves can be tailored to individual project requirements and the specific characteristics of the medium.

If you are interested in working with an experienced industrial valve supplier, please contact us and send your inquiries.

What Is a Gate Valve?

A gate valve is a shut-off valve designed to fully open or completely close the flow of a medium in a pipeline.
 Unlike control valves, gate valves are not intended for throttling flow – their design allows for a fully open flow passage, minimizing pressure loss within the system.

The operating mechanism is based on the vertical movement of a wedge, plate, or knife, which rises during opening and lowers to tightly shut off the flow when closing the valve.
 Thanks to their simple, robust design and ability to operate under a wide range of pressure and temperature conditions, industrial gate valves are among the most commonly used shut-off valves.

Applications of Industrial Gate Valves

Our industrial gate valves are widely used in many industries, including:

  • chemical and petrochemical industry,
  • pulp and paper industry,
  • food and sugar industry,
  • wastewater treatment plants and water utilities,
  • steam, water, gas, and compressed air installations.

Due to the wide variety of available models, Flow Valves gate valves can be used in both low-pressure systems and high-pressure, high-temperature applications.
