Pressure relief
With the valves in closed position, the special design of the sealing seat arrangement ensures safe relief of pressure coming from trapped product (i.e. LNG).
Stable connection
The design of the ERC is based on an overcenter mechanism that grants a stable connection independently from hydraulic pressure and/or friction.
Designed for safely
Thanks to the unique design of the drive mechanism, the valves are simultaneously operated and mechanically interlocked with the ERC. Therefore, it is possible to operate the valves independently from the ERC and without the activation of the emergency release. Furthermore, the activation of the ERS is only allowed after a complete closure of the valves. With the Emco Wheaton’s ERS it is possible to simulate an emergency without real disconnection. This feature allows the Owner to perform routine tests during the all life of the equipment, and, if required, before each loading.
Ensuring Compliance
The Emco Wheaton emergency release system is designed and tested according to OCIMF 4th edition 2019 and ISO 16904. A patent is pending.
