RSK Swing Check Valve for Main & Bypass Feedwater Isolation

The RSK swing check valve is designed for main and bypass feedwater isolation, offering low pressure loss, spherical guiding, and stable performance.

It ensures minimal pressure drop, improving overall plant efficiency and operational performance.

The spherical-guided disc enhances stability and prevents magnetite buildup, ensuring reliable long-term operation.

Overview

The RSK Swing Check Gate Valve is designed to ensure efficient isolation in main and bypass feedwater applications.

Driven by the system medium, it delivers reliable performance with minimal pressure loss, thereby improving overall plant efficiency. The valve is manufactured from forged or cast carbon steel and stainless steel, with sizes up to 29.9 inches (760 mm) and pressure ratings up to Class 1500.

The spherical-guided closing disc enhances operational stability, while a special design with an optional solenoid pilot valve is available for low-flow applications. Its robust construction resists magnetite buildup, making it a durable and efficient solution for demanding isolation services.
