Claims

[Scope of utility model registration request]

A proportional control valve has a valve seat (■) in a part of the valve body (■) and allows a flow rate proportional to the size of the gap formed between the valve body (■) and the needle valve (■) to pass through. The bearing part ■, motor rotor ■, and propulsion screw ■ are integrally formed and housed in the valve body ■, and a seal mechanism is provided to prevent fluid flow between at least the needle valve ■ and the propulsion screw ■. Install the propelling screw ■ so that it is located below the seal mechanism 0, and lubricate the propelling screw ■ with lubricating oil:'! - a proportional control valve configured to be immersed in 1;
