Electrically operated pressure regulating valve - includes slide valve with pressure applied to control chamber determined by operation of electro-valve

摘要

The pressure control valve includes a slide valve (5) whose displacement is controlled by the pressure prevailing in the control chamber (7). The pressure is controlled by a tubular valve closure (11) which, in its upper position, puts the chamber in contact with the fluid outlet orifice (4). The fluid is admitted to the valve by an orifice (2), and displacement of the slide allows control of the pressure in the orifice (3) which supplies a user. The control is supplied from the orifice by a conduit (20). ADVANTAGE - Electrically controlled valve for determining fluid pressure supplied to user.
