SERIES 27
SERIES 27
Valves in this Series are available with single or double solenoid pilots or an air head for remote pressure control.Valve elements have endguided stainless steel stems. Flush flexible manual override buttons are standard on solenoid models. Solenoid models listed in this catalog use an internal pilot supply. They are, however, easily field-convertible for use with an external pilot supply. Models for external pilot supply may also be ordered from ROSS.
To provide special control functions, most models are also available with the following LOGICAIR ® adaptors.

3/2 Valve with Single Solenoid Pilot |
4/2 Valve with Double Solenoid Pilot |
| Timed Sequence Adaptor |
| Allows the actuation and/or de-actuation of a valve to be delayed up to 30 seconds for 2/2 valves, and up to 3 seconds for 3/2 and 4/2 valves. For longer delays see "Q" adaptor below. |
| "PB" Adaptor |
| Increses the actuating force on the valve piston. Useful with low pilot pressure. |
| Air Index Adaptor |
| Allows a single control valve to function as an impulse controlled, detented valve. Successive momentary signals from the same source actuate and de-actuate the valve. |
| "Q" Adaptor |
| The construction of Series 27 valves makes them readily adaptable to vacuum service. For details consult your ROSS distributor or ROSS Technical Services.
