3325 / 3328 – Relay Valves, Normally Open
The 3325 and 3328 are normally open relay valves, used to sequence air flow based on pressure levels. This allows the designer to interlock control functions, or allow for time delays in reversing without damage to sensitive pneumatic or propulsion equipment. The 3325 has a single pilot-to-shift input, whereas the 3328 has two pilot inputs to permit pressure return of the spool.
3326 / 3327 – Relay Valves, Normally Closed
The 3326 and 3327 are normally closed relay valves, used to sequence air flow based on pressure levels. This allows the designer to interlock control functions, or allow for time delays in reversing without damage to sensitive pneumatic or propulsion equipment. The 3326 has a single pilot-to-shift input, whereas the 3327 has two pilot inputs to permit pressure return of the spool.
3329 Pilot Operated Pressure Compensating Relay Valve
The 3329 provides a large volume of air to clutches, brakes or cylinders with a small pilot control with a high degree of accuracy, providing 5/8″ full air flow. The pilot line can be controlled from multiple stations.
3403 / 3405 – Four-Way Air Pilot Directional Control Valve
The 3403 and 3405 are valves created to allow for station transfer on multi-station pneumatic systems. The 3403 / 3405 allow for pneumatic controls to leverage the functionality of various valves to switch the flow and transfer control to a different station.
The 3403 / 3405 valves are constructed entirely of bronze & stainless steel, and are available in 1/4″ NPT and a 1/2″ NPT respectively. The photo shown is of a 3403.
3514 / 3515 – Two Position Three-Way Control Valve
The 3514 and 3515 controls are small, compact mechanical control heads with valves incorporated to allow for station transfer on multi-station pneumatic systems. The 3514 / 3515 has a handle to actuate and switch the flow and transfer control to a different station.
The 3514 / 3515 valves are constructed entirely of bronze & stainless steel, and are available in 1/8″ NPT and a 1/4″ NPT respectively. The photo shown is of a 3514.
3517 – Palm Valve
The 3517 is a small mechanical control head with a palm-sized button for switching the flow and transfer control in a pneumatic system to a different station.
The 3517 is compact, and is constructed entirely of bronze & stainless steel, and is only available in a 1/8″ NPT.
3604 / 3609 – Single Handle Four-Way Directional Pneumatic Control Head
The 3604 and 3609 controls are medium sized mechanical control heads with valves incorporated to allow for station transfer on multi-station pneumatic systems. The 3604 / 3609 has a handle to actuate and switch the flow and transfer control to a different station.
The 3604 / 3609 valves are constructed entirely of bronze & stainless steel, and are available in 1/8″ NPT and a 1/4″ NPT respectively. The photo shown is of a 3609.
4105 Single Direction Pneumatic Throttle Actuators & Positioners
The 4105 is a bronze and stainless steel throttle actuator, equipped with a rolling diaphragm for increased accuracy. The 4105 is meant for light duty applications, and is equipped with a maximum speed stop and idling stop.
The 4105 comes in variable pressure ranges, and has a maximum input pressure of 200 PSI (13.8 BAR) with a 1/4″ NPT
4107 – Single Direction Pneumatic Throttle Actuators & Positioners
The 4107 is a bronze and stainless steel throttle actuator, equipped with a manual override control to allow engine speed setting without air pressure. The 4105 comes equipped with an output rod that is adjustable with double lock nuts, typically meant for medium duty applications.
The 4107 comes in variable pressure ranges, and has a maximum input pressure of 200 PSI (13.8 BAR) with a 1/4″ NPT.
4108 – Single Direction Pneumatic Throttle Actuators & Positioners
The 4108 is a bronze and stainless steel throttle actuator, built with a large bore to provide force for controlling difficult throttle or governor levers. The 4108 comes equipped with an output rod that is adjustable to obtain a precise stroke, and is typically meant for heavy duty applications.
The 4108 comes in variable pressure ranges, and has a maximum input pressure of 200 PSI (13.8 BAR) with a 1/4″ NPT.
4204 – Double Acting Self-Centering Pneumatic Actuator
The 4204 is used for actuating hydraulic or mechanically actuated reverse reduction gear boxes. The 4204 are spring-centred, requiring only 2 control lines for engaging either forward or reverse clutch.
The 4204 is available in either a 2 direction position actuator at 10 to 80 PSI (.7 to 5.5 BAR), or a 3 position self-centering cylinder at 35 to 65 PSI (2.4 to 4.5 BAR)
4207 – Double Acting Self-Centering Pneumatic Actuator
The 4207 is used for actuating hydraulic or mechanically actuated reverse reduction gear boxes. The 4207 are spring-centred, requiring only 2 control lines for engaging either forward or reverse clutch.
The 4207 is available in either a 2 direction position actuator at 10 to 80 PSI (.7 to 5.5 BAR), or a 3 position self-centering cylinder at 25 to 55 PSI (1.7 to 3.8 BAR).
