ED Trim

Model ED choke is designed as a robust control choke with multistage ‘Energy Dissipating’ disk stack trim specifically for applications to avoid cavitation (ie water dumping) and for high energy dissipation such as in high pressure gas production and low noise service.
ED Trim
Several mechanisms are utilized in the design to assist with the conversion of potential energy (pressure) into heat without problems of cavitation in liquids caused by low pressure and the problems of high noise levels with gasses caused by high velocities.

Splitting the flow into a large number of small streams reduces the energy levels in each stream.

Large trim surface area maximizes friction against the fluid.

Large number of changes of direction.
Repeated compression and expansion.

The disk stack has a multiple set of tortuous paths in parallel to each other with each pathway being a series of restrictions in series with each other.

Along each pathway there are restrictions and expansion chambers. In liquid applications the expansion chambers cause swirling of the fluid increasing the number of turns – each chamber is equivalent to approximately 3 turns.

The disks are clamped in position by means of the bonnet bolting. This ensures the stack can be easily extracted and separated for cleaning if it should become necessary.

Trim options include Linear Flow Characteristic, Bi-linear and Tri-linear.
ED trims are custom designed and manufactured to provide application solutions
Plug and Cage, External Sleeve, Positive and Special ED Labyrinth trims are interchangeable in a standard valve body
