PROBLEM TO BE SOLVED: To provide a pressure control valve that can set the pressure control value easily without deteriorating the sealing performance.SOLUTION: A pressure control valve 10 includes: a piston 24 that is disposed in a pressure control chamber 21; a valve 241 that can move in the axial direction together with the piston 24; a valve chamber 22 where an end of the valve 241 is disposed; a valve seat 26 made of resin which the valve 241 is brought into contact with or is separated from; a coil spring 25 that energizes the piston 24 in a direction where the valve 241 is separated from the valve seat 26; and a body member 7 that houses the valve 241 and the valve seat 26. The valve 241 has a hollow cylindrical shape extending in the axial direction, and communicates between the valve chamber 22 and the pressure control chamber 21 when separated from the valve seat 26. The valve seat 26 is movable in the axial direction, and includes an adjusting screw 28 that adjusts the contact position with the valve 241 from the outside by moving the valve seat 26.SELECTED DRAWING: Figure 1 |
