Installation/Operating Instructions
A sandwich regulator is used to provide regulated pressure to individual
valves in a manifolded valve arrangement. Three basic modes of regulation
are available as follows:
Common Port Regulation - Provides adjustable regulated air pressure to
the valve inlet. The regulator is always on the 14 end of the assembly.
Independent Port Regulation - Provides (2) separately adjustable regulated
air pressures, one to each of the valves exhaust passages, or when used
with the by pass plate option on either the 14 or 12 end, one outlet port
pressure is adjustable, the other is at supply pressure.
Selector Regulator - Provides two pressures to port #2 that can be selected
by shifting the main valve. This requires a special manifold.
NOTE: With independent port regulation the valves flow functions are
reversed as indicated by the diagrams to right. Wiring and plumbing
must be adjusted accordingly. (Common Port Regulation does not
affect the valve function.)
!
CAUTION: The reverse valve porting utilized with Independent
Port will reverse the function of 4-Way, 3-Position cylinder to
exhaust and 4-Way, 3-Position inlet to cylinder valves. Utilize
the opposite function valve for normal operation.
Air applied to the sandwich regulator must be filtered to realize maximum
component life.
Factory Pre-Lubrication - Sandwich regulators are pre-lubricated at assembly
with Texaco Marfak MP-2 grease.
!
CAUTION: Do not use synthetic, reconstituted, or oils with an
alcohol content or detergent additive.
!
CAUTION: It is recommended that double solenoid and double
remote air pilot operated 2-Position valves be mounted so that
the axis of the valve spool is in the horizontal plane.

systems only.

NOTE: Solenoid operated valves, when specified with external pilot, may
have operating pressures down to vacuum in the main valve.
External pilot pressure from the inlet and air pilot signals must be
greater than or equal to that in the main valve, but not outside the
ratings above. Valves with sandwich regulators are designed to
use unregulated pilot pressure from the inlet for valve operation.
Table 1 on page 2 shows proper assembly to assure this function.
Ambient Temperature Range:

Voltage Range:
Rated V10%, -15%
!
CAUTION: An interruption of 10 milliseconds or greater to the
power supplied to the solenoid of a solenoid operated valve
may cause the valve to shift. Provision must be made to prevent
power interruption of this duration to avoid unintended,
potentially hazardous, consequences.
NOTE: The regulators shown on the 14 and 12 end of Independent Port
and Selector Units may be replaced with a by pass plate to
provide unregulated pressure.
