P74JA
Differential Pressure Controller
The P74JA Series differential pressure controller is commonly used on water systems to control a pressure differential between supply and return lines. The controller’s SPDT floating action contacts position a modulating valve operated by a motor-driven actuator. In a typical application the valve is located in a bypass line around the system pump. When the system pressure differential increases above the controller’s set point, the valve opens further. More water is diverted through the bypass valve, resulting in a reduction in system pressure differential. A reduction in the pressure differential causes the valve to begin closing and results in an increase in system pressure differential.

FGB.B
Balanced Plug Globe Valve Body

The 2FGB.B Series 2-way Balanced Plug globe valves are engineered specifically for temperature control applications requiring an equal percentage flow characteristic and a high degree of control precision. Common applications include hot water, chilled water and low pressure steam coils and heat exchangers in air handling units, chillers, boilers and cooling towers.

The 2FGB.B Series valves are available with PN16 flanged connections in 2-way configurations. The service port A of all valves is fully closed to port AB with the stem up and fully open with the stem down (push-down-to-open). All 2FGB.B Series valves are operated by MVF Series electric actuators which are ordered separately. The actuators are designed specially for mounting directly to 2FGB.B Series valves without the need of time-consuming field calibration.

 

Working Pressure:            16 bar
Pipe Connection:               PN16 Flange
Flow Characteristics:         equal percentage
Leakage:                           0.03% of Kv “A”, 2% of Kv “B”
Fluid Limitations :              -10…150oC Water(max. 50% Glycol)
                                        
150oC at 2 bar (Steam)
