Breather Valves, Flame Arrestors and Emergency Vent
Pressure Vacuum Relief Valves(Breather Valves)
- Using Elmac’s proprietary software, the required flow area and the diameter of the Pressure Vacuum Relief Valve required to the relieve the normal venting requirements.
- Methods of Valve Sizing as per API-2000 – Co-efficient of discharge method / Flow curve Method.
- Our unique seal design offers ultra tight low leakage, reducing product losses, exceeding the requirements in API 2000 & ISO 28300.
- Minimum requirement is < 1SCFH at 75% of setting according to API 2000 (7th edition) & ISO 28300.
- High flow capacities – Skirted pallet for improved full lift performance.
- Low leakage rates – Air cushion knife edge design seat
