The Series 110 Differential Control Valve is designed to accurately control the pressure difference between any two points. In some systems this means the valve remains closed until pressure differential commands its opening. It is a pilot-operated, modulating type valve which controls pressure accurately and consistently at the desired setting.
Meter Differential Pressure Control:
Installed on the discharge side of a meter, the valve senses high pressure at meter discharge (valve inlet) and low pressure at the meter suction. Valve modulates to hold differential pressure constant, thus assuring meter is provided with a constant pressure for accurate measurement. Filter Bypass Control. In a filtered liquid application where loss of flow cannot be tolerated, the model 110 allows flow should the filter become clogged.
Size Options (mm):
PUMP DIFFERENTIAL CONTROL:
Installed on the discharge side of a pump, the valve senses high pressure at pump discharge (valve inlet) and low pressure at the pump suction. Valve modulates to hold differential pressure constant, thus assuring pump is at optimum point on its curve.
FILTER BYPASS CONTROL:
In a filtered liquid application where loss of flow cannot be tolerated, the model 110 allows flow should the filter become clogged.
The Model 1356 Differential Pressure Pilot controls the amount of pressure in the upper chamber of the main valve
(hence, the degree of opening or closing of the main valve). The pilot senses high pressure under its diaphragm and low pressure above its diaphragm. As the differential increases above the setting of the spring (adjustable), the pilot opens, decreasing the pressure in the main valve diaphragm chamber, allowing the main valve to open a proportionate amount.
Sense line locations.
High pressure sensing is typically at the main valve inlet.
Low pressure can be sensed at the valve outlet or at a field installed remote location.
