Large Diameter Resilient Seated 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.

The Large Diameter Resilient Seated Gate Valve is a high-quality valve designed to provide excellent sealing and durability in large pipeline systems. With its resilient seating, this gate valve ensures a tight seal and prevents leakage even under high-pressure conditions. It is specifically engineered to withstand challenging environments and demanding applications. This valve offers reliable performance and long-term reliability, making it an ideal choice for a variety of industries such as water treatment, wastewater management, oil and gas, and more. Its large diameter allows for efficient flow rate management, while its robust construction ensures longevity and minimal maintenance requirements.
JHY Valve Group has devoted decades of experience to resilient seat gate valves . 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.
