Valves, Actuators & Pump Control


Complete valve testing from AT Technical Services

February 2015 Valves, Actuators & Pump Control

Although plant designers tend to treat them as ‘necessary evils’, it is obvious that control valves play a key role in process quality and reliability. Extreme care must be taken to avoid costly premature failures, possibly resulting in substantial loss and even plant shut-down. Periodical service and testing allows plants to operate for longer intervals.

AT Technical Services’ control valve test units are designed and equipped for:

• High pressure testing.

• Seat leakage classification according to the ANSI/FCI 70-2.

• Stroking of the valve and its controls.

• Total performance testing.

The company’s horizontal control valve test unit is complete with a strong clamping system for quick and easy positioning and clamping of all common Globe, Camflex and Waver type valves in the horizontal position (valve stem vertical). The U-shaped HC10 clamp generates a clamping force of 10 tons and the clamp ensures excellent accessibility for assembly and stroking. The stronger HC combines the above with high pressure liquid and gas testing. The standard HC is complete with sealing adaptors for DIN/ANSI RF flanges, but it also accommodates the use of ‘inner seal’ adaptors for control valves with socket weld ends.

The unit is equipped with a variety of test systems for common control valve test procedure. Optional features include:

• Windows operated computer registrations system.

• Vacuum quick filling system, electronically controlled.

• Hand controlled test and operation systems for actuators.

• Automatic dynamic scans.

• Digital seat leakage measuring systems for gas and liquid.

• Torque test and measuring system 0-500 000 Nm.

• Valve support trolley, mechanically or hydraulically operated.
