Wedge gate valves provide isolation by lowering a wedge-shaped gate between the valve seats. Kad se potpuno otvori, the gate lifts clear of the flow path; kada je zatvoren, the wedge meets the seats to shut off the line.

Farpro’s range includes cast iron, cast steel and stainless steel models, with rising-stem, non-rising-stem and electric operating arrangements. The products below cover different combinations for water networks, utility systems and industrial piping.

Wedge Construction and Shut-Off

The angled seating arrangement is the defining feature of a wedge gate valve. The gate may have a solid or flexible construction, while the sealing surfaces may be metal or resilient-seated, depending on the model. A flexible wedge and a resilient sealing material are different features.

These valves are normally used fully open or fully closed. Holding a standard wedge gate partly open for continuous throttling can expose the gate and seats to wear. For regulating duty, compare a valve designed for flow control.

The stem arrangement affects the space needed for installation. An OS&Y rising stem gives a visible indication of gate travel; an NRS design keeps the external stem height essentially unchanged as the valve operates.

Matching the Wedge Gate Valve to Its Service

For water supply and general utilities, cast iron models offer a familiar isolation arrangement. The Z41X/Z45X resilient-seated series is one option to compare with the metal-seated models in the range.

For industrial process and plant piping, the serija klinastih vrata od lijevanog čelika i stainless steel Z40W/Z41W provide different body and trim combinations. The medium, working temperature and pressure rating guide that material choice.

For media containing fibres or substantial solids, consider whether a different gate construction would suit the duty better. A conventional wedge gate should not be assumed to handle abrasive slurry simply because it is used elsewhere in a mining or process plant.

Other arrangements, uključujući parallel gate i nožasti zasuni, are available within the wider Farpro gate valve range. Naše wedge and parallel gate comparison looks more closely at the structural differences.

A New Line or a Valve to Replace?

planiranje najboljeg proizvoda ventila

For a new line, your piping specification gives us a good starting point. Za zamjenu, the existing valve markings and dimensions often tell us more than the model name alone.

Our team can help compare the available wedge gate models without making the enquiry more complicated than it needs to be. Send us the details you have and let us know what matters most for the installation.
