Valve Actuation & Automation Overview
| Gate Valve Type | Key Features | Primary Applications |
|---|---|---|
| Resilient Seated (RSGV) | Features an elastomer-encapsulated wedge that seals tightly against the inner valve body. Offers zero leakage and smooth, obstruction-free flow passage. | Potable water distribution, sewerage mains, and general fluid isolation complying with AS 2638.2. |
| Metal Seated (MSGV) | Employs precision-machined metal ring seats for high resistance to wear, elevated temperatures, and abrasive media. | Raw water intake, industrial processing, and high-wear piping systems. |
| UL / FM Approved Fire Valves | Certified to international fire protection standards, providing fail-safe shut-off capability under emergency conditions. | Dedicated fire ring mains, hydrant lines, and commercial sprinkler systems. |
| Rising Spindle / Stem (RSGV RS) | The stem rises vertically as the valve opens, providing a clear visual indication of whether the valve is open or closed. | Above-ground plant piping, pump stations, and treatment facilities where visual position check is essential. |
