4023 3-Way Pressure Sensing Valve

SKU 4023

AMOT Model 4023 3-Way Pressure Sensing Valve can be used as a 2 or 3-Way capacity, pressure sensing valve. This valve is ideal for applications that require compressor suction and discharge pressure sensing at high pressure levels. Dual purpose construction provides a wide latitude of applications and permits easy field adjustment or changeover from trip on falling to trip on rising pressure by changing the port piping and re-adjusting the setting. Trip settings are adjustable in eight ranges from 1.2 bar (18 psi) falling to 524 bar (7600 psi) rising pressure.

Operation

 

The 4023 valve is suitable for use on air, hydraulic, or gas control systems with control system pressure up to 8.6 bar (125 psi). The 3-Way valve has a pressure-actuated, spring return operator. Without pressure applied to the sensed pressure port, Port 3 is open to Port 2. With pressure applied to the sensed pressure port, Port 3 closes before Port 1 opens to Port 2.
 
A small dead spot on the center of the stroke prevents valve port overlap. The valve is normally set at the factory so that Port 1 just opens to Port 2 on a pressure rise to the specified tripping pressure setting. The valve is converted to 2-Way action by plugging Port 1 or Port 3.
