Alstom PIB701 + MV7306P16 DEH Servo Control Set

Product Description

The PIB701 is a dedicated servo conditioning & interface board for Alstom Alspa 6000 steam turbine DEH system; MV7306P16 is the complete VP327-series servo valve assembly. This pair forms the closed-loop actuator control loop for turbine governing valve, receiving command from DEH controller, outputting drive signal to servo valve, and collecting LVDT position feedback for valve position closed-loop regulation. It is designed for phosphate ester fire-resistant EH hydraulic oil in thermal power units.

FAQ

Q: What is the relationship between PIB701 and MV7306P16?
A: PIB701 is the electronic interface board inside the DEH cabinet, responsible for signal conversion and feedback acquisition; MV7306P16 is the hydraulic servo valve assembly on the actuator, they work together as one complete governing control channel.

Q: What is the difference between MV7306P16 / P21 / P23?
A: All belong to VP327 series assemblies, the difference is rated flow, manifold interface and internal spool specification, not pin-to-pin interchangeable.

Q: Can PIB701 replace PIB102A or PIB201A?
A: No. PIB701, PIB102A are dedicated servo interface boards with different signal circuit and firmware; PIB201A is general I/O bus board, cannot substitute each other.
