Abstract
A safety module for a process valve and a system comprising a safety module and a process valve are provided. The safety module comprises at least a first interface complementary to a first connection interface of a drive module of the process valve and a second interface complementary to a second connection interface of a process valve actuator of the process valve, such that the safety module can be retrofitted in the process valve. The safety module further comprises at least one safety valve and fluid lines provided for fluidically coupling the safety valve to the drive module and the process valve actuator of the process valve. The at least one safety valve of the safety module is configured for forced venting of the process valve in a safety case.
Claims15
A safety module for a process valve, comprising:
- a first interface having electrical lines and fluid lines for being complementary to a first connection interface of a drive module of the process valve and a second interface having electrical lines and fluid lines for being complementary to a second connection interface of a process valve actuator of the process valve, such that the safety module can be retrofitted in the process valve;
- and
- at least one safety valve and fluid lines provided for fluidically coupling the safety valve to the drive module and the process valve actuator of the process valve,
- wherein the at least one safety valve of the safety module is configured for forced venting of the process valve in a safety case, and
- wherein the first interface includes a first connection face and the second interface includes a second connection face, wherein the first and second connection faces are oriented in opposite directions.
A system comprising:
- a process valve and a safety module,
- wherein the process valve includes a drive module having a first connection interface and a process valve actuator having a second connection interface,
- wherein the safety module includes a first interface having electrical lines and fluid lines for being complementary to the first connection interface of a drive module of the process valve and a second interface having electrical lines and fluid lines for being complementary to the second connection interface of a process valve actuator of the process valve,
- wherein the fluid lines of the safety valve are fluidically coupled to the drive module and the process valve actuator of the process valve,
- wherein, in a retrofitted state, the first interface of the safety module is coupled to the first connection interface of the drive module and the second interface of the safety module is coupled to the second connection interface of the process valve actuator such that at least one safety valve of the safety module and fluid lines of the safety module are fluidically coupled to the drive module and the process valve actuator,
- wherein the safety valve of the safety module is configured for forced venting of the process valve in a safety case, and
- wherein the first interface includes a first connection face and the second interface includes a second connection face, wherein the first and second connection faces are oriented in opposite directions.
