Cowan Dynamics Introduces ZE-ESD Shutoff Valve Solution
The module is a self-contained hydraulic emergency shutdown system in midstream pipeline networks to automate valves that require a fail-safe position where no power source is available.

Valve automation company Cowan Dynamics announced the product release of the ZE-ESD Module that provides mid-stream pipeline distribution networks with a zero-emission emergency shutoff valve actuator system.
Emergency shutoff valves (ESD) are specifically designed to shut off the process within the pipeline in the case of an undesirable event. The ZE-ESD easily works as a drop-in replacement for ESD valves without taking the valve out of operation. The ZE-ESD does not require any power source nor emits fugitive emissions during the operation the actuator.
“There’s been a growing tide of concern over climate change around the world, as well as the desire for suppliers in the oil and gas industry to participate in greener solutions,” said Maria Aguirre, R&D director. “Cowan Dynamics is committed to COP26 and has developed the ZE-ESD to be a zero emission solution for remote ESD valves that have no access to a power source as well ensuring no fugitive emissions are emitted.”
This system is ideal for valves in remote locations that require a self-powered automatic failure position. In the event of an emergency, triggered by an ESD signal, the system will use stored hydraulic pressure to move the valve actuator to the desired fail-safe position (open or close) ensuring an automatic fail-safe system without the need for external power.
The ZE-ESD is compatible with linear and rotary valves such as gate valves, ball valves or butterfly valves. In normal operation the system keeps the valve in its “normal” or “operational” position locked in place. These systems are engineered by Cowan to be retrofitted onto existing pipelines without taking the valve out of service.
