TIS Order Sees SS-690 Reworked For Remote Subsea Operation
TIS Order Sees SS-690 Reworked For Remote Subsea Operation
02 October 2017
TIS Order Sees SS-690 Reworked For Remote Subsea Operation Pressure Tech were asked by our authorised reseller, TIS Hydraulics, to provide a design solution to enable the remote set point control of one of our subsea regulators during its service under water.

As standard, a regulator’s set point is configured according to a customer’s specific requirements during its build at our unit in Glossop, near Manchester, UK. The regulator is then supplied as ‘set and lock’ and any changes after this point must be physically conducted, either prior to system installation or during maintenance intervals.

Our solution? A closed loop actuator.

Through the use of a rotary actuator, the customer is able to control the set pressure point constantly via an electronic signal during regulator operation. The actuator itself is fully sealed, IP69K rated and has a sea water depth rating of up to 3000m, making it perfect for under water control applications.

The use of an actuator required a regulator design adaptation which was successfully provided by the Pressure Tech design department.
