Explosion Vents
Types
| Vent-Saf Explosion Vents | |
| Types VSP™ and VSS™ | Domed single section metal explosion vents with integral gaskets. The dome resists vacuum and vacuum cycling. |
| Type VSP-M™ | A flat, single section explosion panel with integragal frame and gaskets designed for applications in dust collectors, cyclones, conveyors. |
| Type VSP-L | Stainless steel vent designed for low pressures to 0.33 psig (0.022 barg) |
| Type VSE™ | A flat, single section metal explosion vent with integral gaskets designed for near static operating pressures. |
| Type VSB™ | Building vent for protection of building structures by very low pressure explosion vents. |
| Type EXP™ | A flat vent with a slotted 316ss top section and FEP / PTFE seal. |
| Type EXP-V™ | provides vacuum support |
| Type EXP-DV™ | A round domed explosion vent of composite construction with integral vacuum support and gaskets. |
| Type LCV™ | A flat explosion vent of composite construction with integral gaskets. |
| Type HTV™ | A lightly domed vent designed for high temperature service to 1,000°F (538°C) and above. |
Current Certifications
- High operating ratio up to 100% (CE) / 95% (ASME)
- Full vacuum resistance
- Solid metal construction enabling optimum leak tightness
- Designed for non-fragmentation
- Recommended for isolation of pressure relief valves
- Three-dimensional stainless steel tag with product identification and traceability data, as well as code symbol stamps as required
