Product Description
Resilient wedge gate valves are a type of gate valve designed for reliable, bi-directional shutoff without the jamming issues associated with solid wedge gate valves. Instead of a solid metal wedge, they utilize a wedge made of rubber or other elastic material that seals against the valve body.Learn about resilient wedge gate valves, an advanced gate valve design that uses a flexible rubber wedge to achieve bubble-tight shutoff without jamming.
• The primary sealing element is a rubber wedge that compresses against the valve body to achieve shutoff
• The elastic properties of the rubber allow it to deform and match the valve body seals perfectly
• This creates a tight, bubble-tight shutoff in both flow directions
• Since the wedge flexes rather than jamming into place, very little torque is required to operate the valve
• Resilient wedges provide reliable shutoff in both flow directions
• Solid wedge gate valves typically only seal in one direction
• The rubber-to-metal seating reduces friction significantly
• Valves can be operated with handwheels or automated with actuators
• The elastic wedge minimizes damage to valve sealing surfaces
• Resilient wedge gates have a much longer service life than solid wedge designs
• The flexing rubber wedge cannot get stuck in the shutoff position
• Allows for frequent and reliable operation
Resilient wedge gate valves are ideal for water and wastewater pipelines that require regular on/off operation. The bi-directional shutoff and low wear properties make them well-suited for:
• Isolating sections of water distribution mains
• Controlling flows in treatment plant piping
• Regulating discharge from pumping stations
• Prevention of water hammer in hydroelectric plants
• General on/off service in water & wastewater plants
• Resilient wedge gates use a rubber sealing element instead of a solid metal wedge
• The elastic wedge provides shutoff without excessive torque or wear
• Ideal for applications requiring reliable, bi-directional shutoff
