The relief valves in the VS/AM Series (55, 56, 58, 65) are safety devices (SBV) for discharging a certain amount of gas when the pressure at the control point exceeds a given level (bubble-bursting pressure) due to any temporary occurrence such as the momentary shutting of the on/off valve and/or the overheating of the gas with no flow requirement.
VS/AM Series Features
- Reduced overpressures, even at quite high flow rates
- Fast response
