Product Overview

A resilient seated gate valve is a soft-seated isolation valve designed for tight shut-off and zero leakage in water and wastewater pipelines. Featuring a rubber-coated wedge, it provides excellent sealing, corrosion resistance, and smooth operation, making it ideal for municipal water supply, irrigation, fire protection, and industrial water systems.

Product Features

Rubber-coated wedge ensures tight shut-off and zero leakage
Excellent corrosion resistance for long-term service
Smooth, low-torque operation with minimal wear
Suitable for water supply, wastewater, and fire protection systems
Bidirectional sealing performance
Available with rising or non-rising stem designs
Long service life with low maintenance requirements
