3-Way Pilot Valves - AMOT

1 3-Way Pilot ValvesKey features and benefitsl Suitable for use on many types of fluid: l Clean air l Natural gas l LP gases l Petroleum base lubricants l Hydraulic oils l Many other fluidsl Balanced force design, pressure can be applied to any port - simplifies system designl Can be panel or bracket mounted - simple, flexible and low cost installationl Uses the AMOT patented Tad Pole seal - provides lower friction and longer cycle life than conventional O-ringsTypical applications Developed for use in manual and automatic control systems:l Hydraulic fluid controll Actuator controll Pneumatic panel systemsl Safety control systems Models 4057 and 4457 Aluminum and stainless steel versions 4057D Valve (Aluminum)Type 4457A Valve (Stainless Steel)Overview AMOT Models 4057 and 4457 3-Way Valves have been developed for use in manual and automatic hydraulic or pneumatic control systems. They offer versatility in operating requirements and allowable pressure limits. For a 1/4 size control valve, they offer exceptional flow capacity.

The standard spool has a small center dead spot position and no valve port overlap. With the spool fully to the left (rest position), Port 2 is open to Port 3 and Port 1 is closed. With the spool moved to the right (actuated position), OperationPort 2 is open to Port 1 and Port 3 is closed. The Valves are available with a variety of manual and pressure operators and with manual, pressure or spring returns.
