The Essential Industrial Trio: Gate, Globe, and Swing Check
These three valve types often work in tandem within a single pipeline system. Engineered for ruggedness and durability, they are designed to handle the thermal and mechanical stresses of ASME Class 150 to Class 2500 applications.
1. Cast Steel Gate Valves (API 600)
Designed for primary isolation, these valves feature a flexible wedge and Outside Screw and Yoke (OS&Y) construction. The bolted-bonnet design ensures ease of maintenance and a secure seal.
- Best for: Full-bore, "on-off" service with minimal pressure drop.
2. Cast Steel Globe Valves (BS 1873)
While the gate valve handles isolation, the globe valve is the master of throttling and regulation. Its internal S-shaped flow path allows for precise control of flow and pressure.
- Best for: Modulating flow and frequent operation.
3. Cast Steel Swing Check Valves (BS 1868)
Often referred to as Non-Return Valves (NRV), the swing check valve uses a weighted disc that "swings" open with forward flow and automatically slams shut to prevent backflow.
- Best for: Protecting pumps and compressors from flow reversal.
