The Model 10BP regulator ships from the factory, set at approximately midrange. When you install the regulator, use the Knob Assembly to set the required relief pressure, approximately. Full range setting requires about 13 to 16 turns, depending on the range of the unit. Turn the Knob Assembly slowly in a clockwise direction to increase the setpoint or back pressure. Turn the knob in a counterclockwise direction to decrease the setting.
The Model 10BP Regulator uses the force balance principle to open the Relief Valve and vent system pressure when the set point is exceeded.
Downstream pressure is transmitted through the Aspirator Tube to the bottom of the Diaphragm Assembly. When you adjust the range screw for a specific set point, the Range Spring compresses and exerts a force on the top of the Diaphragm Assembly. As long as the pressure acting on the bottom of the Diaphragm Assembly produces a force less than the spring force acting on the top of the Diaphragm Assembly, the Relief Valve remains closed. When system pressure increases, the force on the bottom of the Diaphragm Assembly increases until it reaches the set point. When system pressure increases beyond the set point, the assembly moves upward, lifting the Relief Valve from its seat and vents the downstream air.
If downstream pressure decreases below the set point, the assembly moves downward closing the Relief Valve.
