Performance Automation Solution

Application: automated valve shutdown system retrofit.

March 05, 2014

Automated valve retrofit

This picture is of a recent field retrofit of our customer's automated valve shut down system. This client had an outdated actuator that was not functioning and repair parts could no longer be obtained. We surveyed the site, took field measurements, fabricated mounting hardware components, supplied this new pneumatic actuator, and assisted the customer with the installation. Finally, we confirmed that the product works perfectly on the client's existing control system, therefore assuring our customer that our product performs as it is intended.

Flowserve / Gestra valves on a steam boiler

We recently installed 2 boiler feed pump recirculation valves at a power plant client. These Flowserve / Gestra valves provide high pressure drop and precision flow control during the startup phase of the customer's steam boiler. Additionally, these valves provide leak-tight shutoff after the unit comes online - providing best efficiency and performance of the pumps. The smart digital positioner and the latest control valve trim design will provide years of trouble-free service.

Rotork Electric actuator

Pic is for a valve actuator package being used on a oil production water separation skid destined for delivery to Russia. This Kimray valve was fitted with a custom hardware mount for use with a Rotork CVQ 1200 actuator. The package will provide continuous duty control with positioning resolution of 0.1%. The actuator power supply is 24vdc and the package can be easily set to fail closed, open, or in place depending on customer requirement. We have just completed performance operational and pressure test in our shop.

Application: fireproof refinery unit isolation control.

January 19, 2014

Rotork Electric actuator

This week, we shipped this Rotork electric actuator unit that is headed for safety shut-down service at one of our major refining clients. It is capable of withstanding a 2000 degree F fire for 30 minutes and still be able to close, providing process isolation and safety control for people and equipment. Hopefully it will not be needed, but it will be ready for service if it is required.
