The solenoid pilot utilized on the 1300 Series is the extremely fast and reliable, spring
biased MAC 100 Series three-way manifold valve which features a high flow balanced
poppet. The patented spring biased floating pole piece MACSOLENOID® of the 100 Series
practically eliminates the two most common causes of solenoid valve failures: coil burnout
on AC service and failure to shift. The versatility of the 100 Series permits either internal
or external pilot supply. The solenoid housing incorporates a 1/8" NPTF pilot exhaust
connection which can be either muffled or piped away and the extrenal pilot supply
connection.
MAIN VALVE主閥
The main valve contains a MAC all bonded, lightweight one-piece aluminium spool. All
spool seals are permanently bonded, precision ground and chemically surface hardened
to provide long, stick-free operation. These valves with their pressure balanced design are
not affected by restrictions or back pressure in the exhaust and can be plugged for use
as three-way valves. The one-piece silicon aluminium body used with any of these valves
incorporates an integral accumulator.
ACCUMULATOR累加器
A large accumulator housed in the main valve body supplies both pilots on double
solenoid valves as well as the air assisted spring return on single solenoid pilot or single
remote air pilot operated valves. Internally piloted, the accumulator is protected from inlet
pressure fluctuations in the main valve by a check valve. The check valve is designed to
bleed off the accumulator when the main supply pressure is removed. For external pilot
supply operations, the check valve is reversed, blocking the internal pilot supply to the
accumulator. The accumulator is then supplied through the external supply connection.
DIFFERENTIAL RETURN差別返回
Single solenoid pilot or single air pilot operated models contain a combination spring and
air assisted differential return. Supplied from the accumulator it balances the shifting forces
for consistent operation and positive spool return.
BASES
The 4-port aluminium base design simplifies piping and enables the use of a single muffler
or piped exhaust. They are provided with an integral electricial wiring space, sealed with
a convenient access cover. The access cover also houses the optional indicator lights,
available in voltages of 120/60, 110/50 or 240/60, 220/50 or 24 VDC in either
single or double lights.
