Buckling Pin Relief Valve provides a smart alternative in applications where bursting discs are currently installed or being considered.Buckling Pin technology offers an accurate and reliable means of calibrating pressure relief devices. Buckling pin relief valve for in-line pressure or vacuum relief offering quick and simple external resetting.It is suitable for both gas and liquid applications, and provides a full relief opening at a pre-determined set pressure.
Advantages
- Valve opens in milliseconds
- Quick return to operation after over pressure situation
- Changing the pin is quick and simple
- Pin is outside the process, and therefore unaffected by it
- This means no debris is left in the pipe, as with bursting discs
- No annual testing is required
- Maximum operating pressure is 95% of the set pressure
- Set pressure is much more accurate than bursting discs
- There is zero leakage to set point
- There is no limit on the size of the valve
