Hydraulic unit that opens/closes the large valves of furnace top pressure recovery turbines at steel works with a high level of power and accuracy at high speed

A customer requires more torque for a top pressure recovery turbine to ensure stable operation of the large butterfly valve in the facility.
A customer is looking for not only high-speed and high accuracy but also sufficient reliability to ensure continuous operation.
A customer cannot afford to allocate any professionals to its operation and maintenance because human resources are often limited at steel works.

We can supply sophisticated hydraulic unit that meet the needs of customers in solving the above problems!

We have developed dedicated hydraulic devices for top pressure recovery turbines (TRTs), and manufactured dedicated large hydraulic unit that are in wide use by customers all over the world.
The governor valve is capable of completely closing a butterfly valve with a diameter size of 1800 mm as quickly as 0.5 seconds, but which also provides highly accurate positioning.
The combined use of a logic valve and a servo valve enables the two different controls of normal and urgent.
The number of pipes and joints are reduced by utilizing manifolds and a stacking system, and thereby contributing to better operability and maintainability.

Highly reliable operation is realized as part of the major components of a top pressure power generation facility.
No highly professional techniques are required for operation and maintenance.
The use of an accumulator results in less power consumption as well as the quantities of water and nitrogen needed in operation.

7 to 12 months will be necessary from accepting an order to shipment.

The delivery period may get shortened if the requested specifications are prepared and submitted to us as soon as possible.
