The hole terminates at a flat surface of the valve body, which surface is perpendicular to the operating direction of the actuator of the plunger. The plunger consists of a pad element having a flat face engaging the surface of the valve body, while the opposite face may be flat or spherical, and is engaged by a complementary surface on the end of the actuator.
