NEW CNC machine installed improves machine times by 300%

A new Citizen Miyano CNC machine with twin spindles and twin turrets has now been installed and already proving its worth as a £250k investment by making parts in 1/3rd of the times previously made on the machine it replaced. As our business levels continue to grow and the demand to maintain short lead times increases, the CNC machine from Citizen was viewed as a key piece of equipment required to support the strategic needs of the company.

Pressure Tech completes supply of 108 Hydraulic Regulators with 100% OTIF delivery

Pressure Tech recently completed the supply of 108 x LF690 hydraulic regulators to our Authorised Reseller, Hydraserv, in Norway. The project was for a key system builder supplying several HPUs for a project in Brazil. All 108 regulators were delivered in time and in full to meet with the customers needs.

TIS Order Sees SS-690 Reworked For Remote Subsea Operation

Pressure Tech were asked to provide a design solution to enable the remote set point control of one of our subsea regulators during its service under water. A regulator’s set point is configured during its build at our unit in Glossop, UK. The regulator is then supplied as ‘set and lock’ - any changes after this point must be physically conducted, either prior to system installation or during maintenance intervals. Our solution? A closed loop actuator enabling the customer to control set pressure point constantly via an electronic signal during regulator operation. The actuator is fully sealed, IP69K rated and has a sea water depth rating of up to 3000m.

Project Win in South East Asia
Thanks to hard work by our Malaysian Authorised Reseller ENE Petro Services Sdn Bhd and Pressure Tech Ltd's APAC Sales Manager Walter Koh, we are extremely proud to announce a key milestone achieved in South East Asia. Petronas/MMHE has awarded Pressure Tech the package to install our pressure regulators in the Kasawari Gas Field. The package includes a 1,034 bar (15,000 psi) rated Inconel 625 back pressure regulator / PCV for a Wellhead Control System. Walter commented: "I sincerely thank our client’s trust in us. Together with ENE PETRO, we have worked hard and persevered to win this project. We are proud of this significant achievement and will continue to bring quality products and services to our clients in Malaysia and across the region."
