Question 1

What is an automated valve package?

Accepted Answer

It is an engineering assembly integrating three fundamental components: the process valve, the actuator, and the control accessories. It is delivered tested and certified as a ready-to-install unit.

Question 2

What components does an automated package include?

Accepted Answer

A typical package includes: the valve (ball, gate, globe, or control), the actuator (pneumatic, hydraulic, or electric), the pilot solenoid valve (Versa), the positioner or position switch, the control panel with air preparation (filter-regulator), diagnostic instrumentation, and all mounting brackets and interconnecting tubing.

Question 3

What types of actuators are integrated in the packages?

Accepted Answer

We integrate Perar hydraulic actuators (scotch-yoke for high pressure and large diameter), quarter-turn pneumatic actuators (rack and pinion) and double-piston (scotch-yoke), and electric actuators for remote operation without pneumatic supply. Selection depends on required torque, closing speed, available energy, and functional safety requirements.

Question 4

What is a scotch-yoke actuator?

Accepted Answer

It is a mechanism that converts the linear motion of a piston into 90-degree rotary motion to operate quarter-turn valves. Its advantage is generating maximum torque at the fully open and fully closed positions, exactly where the valve needs it most. Perar actuators use this mechanism with hydraulic cylinders for torques up to 1,000,000 Nm.

Question 5

What testing and certification is performed on the packages?

Accepted Answer

Each package undergoes Factory Acceptance Tests (FAT) that include: hydrostatic body pressure test, seat tightness test, actuator torque verification, stroke time test, instrument calibration, and fail-safe mode verification. Everything is documented with traceable certificates per API 6D and IEC 61511.

Question 6

What is the advantage of buying an integrated package vs separate components?

Accepted Answer

The integrated package guarantees mechanical and functional compatibility between all components, reduces project timelines by eliminating field integration engineering, includes documented FAT testing, and offers a single technical point of responsibility. This translates to fewer installation errors, shorter commissioning time, and a unified warranty.
