Claims

[Scope of utility model registration request]

The valve body 1 is provided with an inlet port 12 and an outlet port 13, and the flow path resistance of a flow path 14 that communicates each of these ports 12 and 13 inside the valve body 1 is controlled by a flow path located within the flow path 14. The valve body 1 is configured to be variable by the moving operation of the valve body 9.
A mounting surface 2 is provided on one end surface, and a mounting surface 25 is provided on one end surface of the sensor plate 3 to which the pressure sensor 24 is mounted, and the sensor plate 3 is mounted on the mounting surface 25 at a plurality of mutually different mounting positions. It is configured so that it can be attached to the valve body 1 in close contact with the mounting surface 2, and a first sensor port 22 is provided on the mounting surface 2 to communicate with the pressure detection port 20 through the inside of the valve body 1. a second sensor port 27 that passes through the inside of the sensor plate 3 on the surface 25 and communicates with the pressure sensitive part of the pressure sensor 24;
29, 30, and the first sensor port 22 and the second sensor port 27, 29, 30 are configured to communicate with each other at each attachment position of the sensor plate 3 to the valve body 1. Control valve with pressure sensor.
