Back-pressure regulators control inlet pressure by balancing an adjustable spring force against the force of the inlet pressure. The spring force is adjusted by turning the stem/handle, which sets the desired inlet pressure. When the force rises above the force of the spring, the regulator opens until the spring force and inlet pressure are balanced again.
