Claims

[Scope of utility model registration request]

An inflow port and an outflow port are formed in the valve housing, and from the inflow port. A compensator valve and a throttle valve are sequentially provided in the connection path to the outlet, and the force of the spring in the spring chamber and the pressure of the connection path between the throttle valve and the compensator valve and the outlet act on the compensator valve to reduce the throttle valve. In the type that adjusts the flow rate by keeping the differential pressure before and after the spring constant, the pressure at the inlet is guided through a pilot circuit equipped with a pilot flow control valve in the spring chamber, and the pressure at the inlet is A flow rate adjustment valve connected to a pilot valve that controls the pressure in the chamber.
