OEM/ODM, China-Made, RESILIENT SEAT GATE VALVE(DI PIPE)

The Resilient Seat Gate Valve (RSGV) designed for Ductile Iron (DI) pipes is a critical component in modern water supply, fire protection, and industrial piping networks. Combining the robustness of ductile iron construction with advanced resilient seating technology, this valve ensures leak-proof performance, easy operation, and long-term durability.

Key Features & Benefits
1. Resilient Seat Design
Bubble-Tight Shutoff: The EPDM or NBR rubber seat provides excellent sealing, even in systems with sand or minor debris.

Low Torque Operation: Smooth opening/closing reduces wear on actuators and manual handwheels.

Corrosion Resistance: Unlike metal-seated valves, the rubber lining prevents scaling and mineral buildup.

2. Ductile Iron (DI) Body Construction
High Strength: DI offers superior impact resistance compared to cast iron.

Corrosion Protection: Standard epoxy-coated interior/exterior prevents rust in buried or wet environments.

Pressure Rating: Typically rated for PN10/PN16 (150/200 psi), suitable for municipal and industrial water systems.

3. Flanged or Plain End Connection
Compatible with DI pipes (EN 545/EN 598 standards).

Flanged ends for bolted connections or plain ends for mechanical joint (MJ) or push-fit installations.

4. Full Bore Design
Minimal pressure drop for efficient flow in water distribution networks.

No sediment buildup, reducing maintenance needs.

Installation & Maintenance Tips
Alignment: Ensure proper pipe alignment to avoid seat distortion.

Buried Service: Use protective wrapping for underground installations.

Cycling: Exercise valves periodically to prevent seat adhesion.

Inspection: Check rubber seats every 2–3 years for wear.

Lower lifecycle cost (reduced repair/operational expenses).

Compliance with ISO 5208, EN 1074, AWWA C515 standards.

The Resilient Seat Gate Valve (DI Pipe) is the modern standard for reliable, low-maintenance flow control in water systems. Its rubber-sealed design eliminates common leakage issues of traditional gate valves, while the ductile iron body ensures structural integrity under pressure. For utilities, contractors, and engineers, this valve delivers performance, durability, and cost savings—making it the smart choice for new installations and retrofits.
