P-161
2-W Pressure Reducing Pilot
Valve Diameter 1"- 14"
 
Application 
The P-161, 2-W pilot, operates when hydraulic pressure is applied below the spring loaded membrane which is connected to the pilot's seal trim.
The P-161 is Normally Open (N.O.) pilot. Once pipeline pressure is built downstream of the main valve, it will be conveyed to the pilot's membrane through the sensor port. When the pressure surpasses the set point (pre adjusted thorugh the pilot's adjusting screw) the membrane moves upwards and water passage closes, closing the main valve. When the downstream pressure reduces below the pilot's set point, the membrane moves downwards and opening the water passage.

Kv rate: 0.25 (l/sec)
Sensitivity: 0.1 bar
Max. temperature: 90C

P-162
2-W Pressure Reducing Pilot
Valve Diameter 1"- 14"
 
Application
The P-162, 2-W pilot, operates when hydraulic pressure is applied below the spring loaded membrane which is connected to the pilot's seal trim.
The P-162 is Normally Open (N.O.) pilot. Once pipeline pressure is built downstream of the main valve, it will be conveyed to the pilot's membrane through the sensor port. When the pressure surpasses the set point (pre adjusted thorugh the pilot's adjusting screw) the membrane moves upwards and water passage closes, closing the main valve. When the downstream pressure reduces below the pilot's set point, the membrane moves downwards and opening the water passage and allowing the main valve to open.

P-181
2-W Pressure Sustaining/Relief Pilot
Valve Diameter 1"- 14"
 
Application
The P-181, 2-W pilot, operates when hydraulic pressure is applied below the spring loaded membrane which is connected to the pilot's seal trim.
The P-181 is Normally Closed (N.C.) pilot. When no pressure is applied below the spring loaded membrane, the pilot commands the main valve to close. When the pressure surpasses the set point, the membrane moves upwards and water passage opens, opening the main valve. When the downstream pressure reduces below the pilot's set point, the membrane moves downwards, closing the water passage.
During the pilot's operation water circulates constantly through the pilot, it provides an immediate response to any changes in pipeline pressure.

P-182
2-W Pressure Sustaining/Relief Pilot
Valve Diameter 1"- 14"
 
Application
The P-182, 2-W pilot, operates when hydraulic pressure is applied below the spring loaded membrane which is connected to the pilot's seal trim.
The P-182 is Normally Closed (N.C.) pilot. When no pressure is applied below the spring loaded membrane, the pilot commands the main valve to close. When the pressure surpasses the set point, the membrane moves upwards and water passage opens, opening the main valve. When the downstream pressure reduces below the pilot's set point, the membrane moves downwards, closing the water passage.
During the pilot's operation water circulates constantly through the pilot, it provides an immediate response to any changes in pipeline pressure.

P-683
3-W Pressure Sustaining/Reducing Pilot
Valve Diameter 1"- 14"
 
Application
The P-683 operates only if pipeline coniditons changes, when hydraulic pressure is applied below the spring loaded membrane, which is connected to the pilot's seal trim, alternating the pilot's water passage.
When the pilot reaches the desired set point, the seal trim locks all water passages, there is no water flow in the pilot and the pilot remains in this position until a change is the downstream pressure.
The P-683 can be used either as a Normally Open (N.O.) or Normally Close (N.C.)
 
N.O. Configuration
When the pressure head in the pilot's sensor port is lower than the set point, the membrane moves downwards, closing pressure supply to the control chamber and opening a water passage. Once pressure head is built, the membrane moves upwards opening the pressure supply to the control chamber and closing the pilot's vent, allowing the main valve to close.

  P-10
2-W Flow Level Pilot
Valve Diameter 1"- 6D"
 
Application
The P-10 is a flow pilot that is interconnected by a lever arm. When water level reaches its maximum level, the float rises, closing the water passage of the pilot and commands the main valve to close.
When water level drops, the float opens the water passage and main valve will open.
Every change in water level is conveyed to the pilot directly through the lever arm.
The pilot's water passage will open proportionally to the water level.
The P-10 is usually used to command level control valves in small and medium water reservoirs.
There is no need for energy other than line pressure; it offers an economic control solution.

  P-100
2-W Differential Pilot
Valve Diameter 1"- 14"
 
Application
The P-100 is a Normally Open (N.O.) and a differential pilot. The P-100 operates when hydraulic pressure is applied below and above the spring loaded membrane which is connected to the pilot's seal trim. Upper and lower chambers of the pilot are connected to upstream and downstream sides of a calibrated orifice plate, used as a flow sensor. Differential pressure across the orifice changes with flow, and conveyed to the pilot through its sensing ports. When low pressure difference is presented across the orifice plate, the valve opens. When pressure difference increases, the valve tends to close, maintaining the requested flow.
