Big Size Resilient Wedge Flanged Gate Valve
- Tight Shutoff – The resilient seat provides a tight seal when the gate is fully closed for positive isolation.
- Low Torque Operation – Requires less torque to operate the valve due to low friction against the resilient seat.
- Bubble-Tight Bidirectional Sealing – Resilient seat provides bidirectional sealing for bubble-tight shutoff in both flow directions.
- Reduced Pressure Loss – The smooth contoured body and gate design minimizes pressure loss across the valve.
- Erosion Resistant – The resilient seat material resists erosion from high velocity fluids.
- Low Maintenance – No re-grinding or lapping of seats required compared to metal seats.
- Long Service Life – Resilient seats withstand more contact cycles before replacement than metal seats.
- Stem Sealing – Multiple stem seal options prevent internal and external leaks.
- ADA Compliance – Complies with Americans with Disabilities Act (ADA) for operating torque requirements.
- Customizable – Valve size, materials, connections can be customized for the application.

What is a resilient wedge gate valve?
A resilient wedge gate valve is a type of valve used in various industries, particularly in water and sewage applications. It’s named for its key component, the resilient wedge, which is designed to withstand the rigors of harsh conditions and provide a tight seal when the valve is closed.
This type of valve operates by lifting a round or rectangular gate out of the path of the fluid. The sealing surfaces between the gate and seats are planar, so this type of valve can be manufactured to provide either a tight seal or merely to restrict or regulate flow.
“Resilient”: This indicates the valve’s capacity to endure or bounce back quickly from challenging conditions. In this case, it signifies the valve’s durability and its ability to function under a variety of pressures and temperatures.
“Wedge”: This refers to the component of the valve that manipulates the fluid flow. It’s named a wedge due to its triangular shape, which allows it to fit perfectly into the valve seat to halt fluid flow when the valve is shut.
What is the function of the resilient wedge gate valve?
Major strengths of resilient wedge gate valve
JHY Valve Group has devoted decades of experience to big size resilient seated gate valves – Shop our extensive range of large diameter resilient seated gate valves sized NPS 12 up to NPS 100. Featuring robust wafer or lug body designs, these valves deliver reliable isolation and flow control across water treatment plants, chemical processing, power plants and various industrial applications. Select from a variety of resilient seat materials. . To produce high-quality and constantly improved gate valve, there are 7 major strengths:
1. Body material is GGG40/50 ductile iron, casted in Jhy-self own foundry, which is qualified under EN-GJS-400-15 or EN-GJS-500-7, and the spheroidization rate is over 96%!
2. The duplex stainless steel spindle enables smooth operation, and one piece design makes sure better resistance to axial load and can withstand high operation torques.
3. O-rings inside the cap can guarantee the seal function performing well in the long usage life.
4. Bolts and nuts is DACROMET®or GEOMET® approved, better anti-corrosion to ensure stability.
5. New designed rubber disc encapsulated by Jhy-self ensuring a low operating torque even under high pressure and preventing damage or corrosion generated by the friction.
6. Free wedge nut design, reduces the stem bending forces and enables it to be easily replaced.
7. Before epoxy powder coating, Jhy always do shot blasting on castings, and the powder is WRAS approved. The coating thickness is over 250-300μm sprayed under the temperature over 200℃, which ensures coating surface smooth, strong adhesive and not cracked later. More importantly, the technology adopted is environment friendly.
At JHY, we offer a diverse range of resilient wedge gate valves, each meticulously designed to meet the stringent demands of various industries. Our product catalog is extensive, featuring valves renowned for their durability and their ability to function under a wide array of pressures and temperatures.Our valves are renowned for their durability and their ability to function under a wide array of pressures and temperatures, making them a reliable choice for controlling fluid flow in any system. The primary function of a valve is to regulate the flow of fluid. In a resilient wedge gate valve, the gate can be raised or lowered to allow more or less fluid to pass through. When the gate is fully raised, the fluid flows freely, and when it is fully lowered, it fits snugly into the valve seat, effectively halting the flow. At JHY, we believe in the power of knowledge. We provide resources and training on the valve basics , the operation of resilient wedge gate valves, and best practices for valve maintenance and troubleshooting. Our team of experts is always on standby to answer your questions and provide the support you need.
