摘要： A fluid control valve, which can control a fluid having a pressure in the order of 10 kg/cm2, has a response time in the order of several milliseconds can be made small in size, and a fluid supply/exhaust system that provides less gas counter flow in the event of a plurality of valves being used. A fluid control valve of the invention controls a fluid moving in a valve body by closing and opening a portion between a valve seat and a valve holder by use of a drive unit. The drive unit has a rod-shaped shaft for application of pressure through the valve seat and the valve holder, and a member “a” fixed around the rod-shaped shaft. The member “a” is made from a magnetic material, and has a space between it and the shaft. A coil provided in parallel to the shaft, moves the shaft via the member “a” up and down by electromagnetic induction, and makes use of a spring force to close and open a portion between the valve seat and the valve holder.

摘要： A control valve device develops opening/closing accuracy of a valve assembly. The valve head 310a is configured to open and close a transfer path formed in the valve housing 305 by transmitting the power to the valve assembly 310 from the power transmission member according to a pressure ratio between working fluid supplied to the first space Us and the second space Ls, respectively. The valve head has a Vickers hardness larger than a Vickers hardness of a valve seat of the transfer path to be in contact with the valve head, and a hardness difference therebetween is set to be about 200 Hv to about 300 Hv.
