Prospector Series Poppet Valves
Air Pilot Operated Inline & Subbase Valves
Options Information
For optional features, note the valve model number that comes closest to the desired valve from the preceding order table. Change the model
number as shown in the following diagram to obtain the desired option. For example: the ordering table on VAL-12-21 shows D1022C-00-A1, a
3-port/2-position single air pilot operated valve with spring return. To use this valve with a twin operator, change the last two digits to A4, as shown
below.

M OMENTARY S IGNAL O PERATOR : Used when it is desirable
to control the valve with 2 alternately applied
momentary signals of 0.2 second minimum duration
(first signal shifts and hold the poppet; the second
allows the poppet to return to its normal position).
Available only on 3-port/2-position normally closed
valves and on 4-port/2 position (4-way) valves. Be sure
to change the 6th, 9th and 10th positions of the model
number.
§§ T WIN O PERATOR : Allows independent operation of each
valve element. Available only on 4-port/2-position
(4-way) valves.
* R EPAIR K IT : Available for A6 operator. Kit contains all
elastomers necessary to service one operator body. To
order, request: 53476-01.
To calculate the weight of a valve and optional operator take the weight given for the relevant valve from the ordering tables, subtract either 0.29 lbs (0.13 kg) for an
A1 operator and add the weight given above for the appropriate optional operator.
For example: For D1022C-00-A1 has a listed weight of 1.79 lbs (0.81 kg ). To convert this to a Momentary Signal Operator,
i.e. D1022C-00-A6
➔ 0.81 - 0.13 + 0.17 = 0.85 kg (1.87 lbs.)
Example model number is a 3-port/2-position (3-way) normally
closed valve with a single air operator, and spring return.
Vacuum Service
§
For on-off application of vacuum, use a
normally closed 2-port/2-position (2-way) valve.
When the valve is actuated, vacuum will be
applied to the outlet port.
For selecting alternately between vacuum and
pressure, use a normally open 3-port/2-position
(3-way) valve. Connect the vacuum to the exhaust
port and pressure to the inlet port. When the
valve is actuated, vacuum will be applied to the
outlet port.
For selecting alternately between vacuum and
vent, use a normally open 3-port/2-position (3-
way) valve. Connect the vacuum to the exhaust
port and vent the inlet port. When the valve is
actuated, vacuum will be applied to the outlet
port.
In addition, a 4-port/2-position (4-way) valve
can be connected the same way as 3-port/2-
position (3-way) valves for selecting alternately
between vacuum and pressure or vacuum and
vent. That is, connect the vacuum to the exhaust
port and pressure or vent to the inlet port. When
the valve is actuated, the cylinder ports (outlets)
will be alternately switched between vacuum and
pressure or vacuum and vent.
