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.
The 3325 / 3328 valves are available in a variety of light to heavy duty spring configurations. Constructed of bronze and stainless steel, these units have 1/4" NPT ports and are rated to maximum supply pressure of 200 PSI (13.8 BAR). Photo shown is of a 3325.

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.
The 3326 / 3327 valves are available in a variety of light to heavy duty spring configurations. Constructed of bronze and stainless steel, these units have 1/4" NPT ports and are rated to maximum supply pressure of 200 PSI (13.8 BAR). Photo shown is of a 3327.

3329 Pilot Operated Pressure Compensating Relay Valve
The 3329 relay valve allows for precise control over clutches, brakes or cylinders using a small pilot signal. The valve moves a large volume of air with a high degree of accuracy and minimal hysterisis. The pilot line can be controlled from multiple stations.
The 3329 is constructed using bronze and stainless steel and is water tight, allowing for use in harsh environments. The 3329 is typically used with pneumatic control heads to ensure controlled flow into systems that require precise pressure control.

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.
