A resilient seated gate valve is a linear-motion valve that uses a rubber-lined wedge to create a bubble-tight seal against the valve body. Unlike metal-seated gate valves that rely on metal-to-metal contact, the resilient seat design compensates for minor debris and imperfections in the flow stream, ensuring reliable shut-off even in demanding water and wastewater service.
This model is a rising stem (OS&Y) gate valve–the stem rises and lowers with the wedge, providing a clear visual indication of the valve's position. When the stem is fully raised, the valve is open; when fully lowered, the valve is closed. This makes it ideal for applications where operators need to confirm valve status at a glance, such as in water treatment plants, pump stations, and fire protection systems.
The valve is manufactured to JIS 10K and BS5163 standards, ensuring compatibility with Japanese and British piping systems. It features a CI (gray iron) body and handwheel operation for reliable manual control. The resilient EPDM seat is fully vulcanized (cured) onto the wedge, providing a permanent, leak-free bond that resists displacement under high flow velocities.
As a direct OEM/ODM manufacturer with over 19 years of export experience, Tianjin Worlds Valve Co., Ltd. delivers fully customizable resilient seated gate valves–materials, sizes, pressure ratings, flange standards, coatings, and operation methods–all tailored to your exact specifications. Our products are exported to more than 50 countries and backed by ISO 9001 (certified by LRQA), CE, UKCA, WRAS, and ACS certifications.

1. Rising Stem (OS&Y) Design–Visual Position Indication
Clear Position Indicator–The rising stem provides immediate visual confirmation of valve status–stem up means open, stem down means closed. No guesswork, no accidental operation.
Suitable for Underground Installation–With a stem extension, the rising stem design allows operation from above ground, making it ideal for buried pipelines and valve boxes.
Easy Maintenance–The stem packing can be adjusted or replaced without removing the valve from the pipeline, reducing downtime.
2. Body Material–CI (Gray Iron)
Reliable Strength–Gray iron provides adequate mechanical strength for JIS 10K and BS5163 service in water and wastewater applications.
Excellent Machinability–The material allows precise casting and tight dimensional tolerances, ensuring reliable flange sealing and smooth wedge operation.
Cost-Effective Solution–CI offers an economical choice for general-purpose industrial and municipal service.
3. Resilient Seated Wedge–Bubble-Tight Shut-Off
EPDM Vulcanized Seat–The EPDM rubber seat is permanently bonded to the wedge through high-temperature vulcanization, eliminating any gaps or leak paths between the seat and wedge.
Compensates for Debris–The resilient rubber surface compresses around minor debris and particles, maintaining a tight seal even in less-than-perfect water conditions.
Bubble-Tight Performance–Tested to EN12266-1, the resilient seat provides zero-leakage shut-off, making it ideal for potable water and critical isolation applications.
4. Handwheel Operation–Reliable Manual Control
Simple, Reliable Operation–The handwheel provides direct mechanical control with clear tactile feedback–no power supply or control system required.
Low Operating Torque–The wedge design and rising stem thread mechanism reduce operating torque, making manual operation smooth and effortless.
Locking Device Available–Optional locking nut or padlock provision prevents unauthorized operation.
5. JIS 10K / BS5163 Compliance–International Standard Compatibility
JIS 10K–Complies with Japanese Industrial Standards for 10 bar service, with flange dimensions to JIS B2212–suitable for projects in Japan and other JIS-standard regions.
BS5163–Complies with British Standard for resilient seated gate valves, with flange dimensions to BS4504–suitable for UK and Commonwealth projects.
Dual Standard Flexibility–One valve, two major international standards–simplifying procurement and inventory management for multinational projects.
