Swagelok® Process Interface Valves (Double Block and Bleed)
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 InformationCommonly used in the oil and gas, chemical and refining, and power generation markets, Swagelok process interface valves (double block and bleed valves) can be used at process piping installation points, in vents or drains, at chemical injection and sampling points, directly mounted to instruments, for close coupling of instruments, for 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 options per API 641, API 624, ISO 15848-1, ISO 15848-2 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 and VS04 series)
- Three-piece bolted body valves (VS03 series)
- Process monoflanges (MS series)
Single block and bleed, block combinations, and block and bleed globe valve modules are also available.
