Gate Valves

Gate valves are industrial piping equipment used to fully stop or start flow in fluid control, offering high sealing and low pressure loss thanks to their sliding closure mechanism. ORFA Industrial offers a range of gate valves optimized for main water lines, wastewater facilities, and power plants, suitable for heavy-duty conditions, with the advantage of extensive stock. Professional gate valves, distinguished by their bi-directional sealing and full-bore internal structure, ensure piping safety with ORFA quality.

What Are Gate Valves and Their Applications

Gate valves are mechanical isolation elements that operate by the vertical movement of a gate, perpendicular to the flow direction. These gate valves, which do not create turbulence in the fully open position, minimize pressure loss as they have the same passage area as the pipeline diameter. ORFA Industrial recommends the use of professional gate valves, especially in main supply lines where flow is rarely interrupted but requires complete sealing when it is. Available in flexible wedge or knife gate types, gate valves deliver high performance in wastewater and sludge-laden water transfer applications due to their structure that is unaffected by particles in the liquid. Thanks to their durable body designs, gate valves provide reliable isolation in extreme pressure classes.

Types and Technical Structure of Gate Valves

Different gate valves models are available in our stock depending on the chemical composition of the fluid and the installation depth. The main product groups offered under ORFA are as follows:

Choosing the Right Gate Valves

For the longevity of your installation, gate valves should be selected according to the pressure class (PN10, PN16, PN25) and the abrasiveness level of the fluid. Selecting the wrong valve type can lead to locking due to scaling on the gate valves wedge or loss of sealing. With ORFA engineering support, we determine the most efficient gate valves configuration for your project and maximize system life with corrosion-resistant epoxy coating options. Modern gate valves offer operational convenience with their structure compatible with electric actuator or gearbox (handwheel) mounting. High-strength professional gate valves are the most reliable isolation points in heavy industry and infrastructure projects. An investment in quality gate valves ensures complete sealing control of the fluid passing through the line.
