Swagelok® Process Interface Valves (DBB)
Swagelok process interface valves enable a smooth transition from the process piping system to instrumentation in a single configuration, providing fewer potential leak points, lower installed weight, and a smaller space envelope.Request More Information
Commonly used in the oil and gas, chemical and refining, and power generation markets, Swagelok process interface valves can be found at process piping installation points, in vents or drains, at chemical injection and sampling points, directly mounted to instruments, providing close coupling of instruments, providing double block and bleed isolation, or in extreme service applications.
Swagelok process valves have up to 75% lower installed weights and smaller footprints compared to assemblies featuring multiple valves and fittings, and they have fewer potential leak points. They also provide reduced installation time, reduced vibration stress, and reduced fugitive emissions (low emissions certification per API 641 and API 624 available), as are designs featuring materials listed in accordance with NACE MR0175/ISO 15156 for sour gas service. Integral Swagelok tube fitting connection options are also available.
The Swagelok family of process interface valves includes:
- One-piece forged body valves (VB04 series)
- Three-piece bolted body valves (VB03 series)
- Process monoflanges (MN0 series)
- Reduced fugitive emissions valves (VB05 series)
- All-needle valves (VN01 series)
Swagelok process interface valves and process monoflanges can be configured to suit a variety of special applications. In addition to double block and bleed assemblies, single block and bleed, and block combinations are available. Block and bleed globe valve module options are also available.
