FIELD: machine building.
SUBSTANCE: group of inventions relates to the field of automation and is intended for use in industrial and housing applications for monitoring of pressure of fluid medium downstream a valve. The pressure regulation valve comprises the balanced insert valve. The balanced insert valve has a lock with the central passage. The central passage has a valve seat and a valve stem, interacting for valve opening and closing. One end of the central passage is plugged with the end plug, with blind passage for partial intake of the valve stem. The fluid medium pressure downstream the valve is transmitted into the blind passage through the hollow part of the valve stem that results in balancing of the valve stem in a lock. There is a design version for implementation of the balanced insert valve and the method of conversion of unbalanced valve into balanced valve.
EFFECT: group of inventions is aimed at increase of life expectancy, reliability and precision of valve operation.
