Pressure Sensing Valve - Model 4023 Overview AMOT Model 4023 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. Trip settings are adjustable in eight ranges from 1.2 bar (18 psi) falling to 524 bar (7600 psi) rising pressure. The 4023 valve is suitable for use on air, hydraulic, or gas control systems with control systems pressure up to 8.6 bar (125) psi. Typical applications • Well head control • Actuator piloting valve • Suction/discharge pressure Key features and benefits • Setting to 524 bar (7600 psi) • 2 or 3-way action • Balanced 3-way valve - pressure can be applied to any port • 3-way valve suitable for LP gases, natural gas, oil, air etc • Bubble-tight seals with center dead spot (no port overlap) • Field adjustable - rising or falling • Adjustable setpoint • Gulfproof finish standard

Pressure Sensing Valve - Model 4023 Operation 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. A manual reset feature is...

[Risrig Pressure Only) Pressure Range Codes 5 & 6. Pressure Range Properly applied and installed 4023 valves require minimal maintenance. Unless leakage or other problems are noticed earlier, an inspection of the units at yearly intervals is adequate to detect and make provision for normal wear and preventive It is recommended that Model 4023 be checked monthly for proper functioning by simulating an unsafe condition.
