FIELD: mining; physics.
SUBSTANCE: device includes seat and ferromagnetic valve, the seat being equipped with a permanent magnet system, while the valve has ferromagnetic inserts with Curie magnetic transition point equal to oil temperature at the sampling site.
EFFECT: improved device efficiency due to actuating valve device at given oil sampling site and creating additional press force.
