Gate Valve

Gate Valve Manufacturer in Canada

Gate valves are widely used for complete flow isolation, ensuring reliable shut-off and minimal pressure loss in industrial pipelines. Recognized as a prominent Gate Valve Manufacturer in Canada, ValvesOnly Canada supplies premium industrial gate valves across Toronto, Calgary, Edmonton, Vancouver, Montreal, and throughout Canada. 

What Is the Purpose of a Gate Valve? 

A gate valve is an isolating valve which operates by lifting the gate or wedge into position in order to open up the entire passage or to block it altogether. Once opened, the full bore design allows the media to flow without any obstruction, and thus it is widely used where unobstructed flow is of primary importance.

How Does a Gate Valve Control Flow? 

Gate valves work on the principle of lifting a gate either flat or wedged shaped along with the shaft of the handwheel either upwards to open the passage for flow or downwards to block flow by pressing the gate onto the seat. As the design is meant for only fully open or closed conditions, therefore the gate valves are not used for throttling purposes.

Gate Valve Standards and Testing:

Every gate valve is designed to API 600, API 602, API 6D, ASME B16.34, BS 5163, and DIN 3352. Testing follows API 598, covering hydrostatic shell testing, seat leakage testing, backseat testing where applicable, and functional checks on stem, wedge, and seating operation.

Gate Valve Features and Benefits:

  • Full-bore construction for minimal pressure drop
  • Rising stem and non-rising stem options
  • Soft seated or metal seated configurations
  • Forged and cast construction available
  • Suitable for manual and automated operation
  • Built for both low-pressure and high-pressure service

Gate Valve Applications and Industries:

ValvesOnly Canada gate valves support isolation duty across oil and gas processing, power generation, water treatment and distribution, petrochemical and refinery systems, marine and offshore operations.

Gate Valve Selection Guide:

When selecting the right gate valve, it is necessary to select the right pressure class, right media, right temperature, and right stem type depending on the requirements of your project. However, should there be a wrong choice, you might face trouble in the future.

ValvesOnly Canada analyzes all of these factors directly with you to provide the necessary configuration and grade of materials for the effective operation of the valves in the long term.
