DESCRIPTION

Series 8262 and 8263 valves are 2-way direct-acting general service
solenoid valves. Valves bodies are of rugged brass or stainless steel.
Series 8262 or 8263 valves may be provided with a general purpose
or explosionproof solenoid enclosure. Series 8262 and 8263 valves
with suffi x "P" in the catalog number are designed for dry inert gas
and non-lubricated air service.
Notice: Brass valves are not certifi ed as lead-free under the Safe
Water Drinking Act SWDA 1417 and are not intended for use on
drinking water systems. They are intended for control of water
in industrial applications. Consult ASCO for valves rated for use
in potable water applications.

OPERATION

Normally Open: Valve is open when solenoid is de-energized;
closed when is energized.
Normally Closed: Valve is closed when solenoid is de-energized;
open when energized.
IMPORTANT: No minimum operating pressure required.

Manual Operation

Manual operator allows manual operation when desired or during an
electrical power outage. Depending upon basic valve construction,
three types of manual operators are available:
Push Type Manual Operator
To engage push type manual operator, push stem at base of valve
body upward as far as possible. Valve will now be in the same position
as when the solenoid is energized. To disengage manual operator,
release stem. Manual operator will return to original position.
Screw Type Manual Operator
To engage screw type manual operator, rotate stem at base of the
valve body clockwise until it hits a stop. Valve will now be in the
same position as when the solenoid is energized. To disengage,
rotate stem counterclockwise until it hits a stop.
CAUTION: For valve to operate electrically, manual
operator stem must be fully rotated counterclockwise.
Stem/Lever Type Manual Operator
To engage manual operator, turn stem/lever clockwise until it hits a
stop. Valve will now be in the same position as when the solenoid is
energized. To disengage manual operator, turn stem/lever counter-
clockwise until it hits a stop.
CAUTION: For valve to operate electrically, manual
operator stem/lever must be fully rotated counterclockwise.

Flow Metering Devices

Valves with suffi x "M" in catalog number are provided with a
metering device for fl ow control. Turn stem to right to reduce fl ow;
left to increase fl ow.

Check nameplate for correct catalog number, pressure, voltage,
frequency, and service. Never apply incompatible fl uids or exceed
pressure rating of the valve. Installation and valve maintenance to
be performed by qualifi ed personnel.
Note: Inlet port will either be marked "I" or "IN". Outlet port will
be marked "2" or "OUT".

Future Service Considerations

Provision should be made for performing seat leakage, external
leakage, and operational tests on the valve with a nonhazardous,non-
combustible fl uid after disassembly and reassembly.

Temperature Limitations

For maximum valve ambient and fl uid temperatures, refer to charts
below. Check catalog number, coil prefi x, suffi x, and watt rating on
nameplate to determine the maximum temperatures.

Catalog Nos.8262B200 and 8262 C200 AC construction only and
Catalog Nos. 8262B214 and 8262 D200 AC and DC construction
are limited to 140ºF fl uid temperature.
Valves with Suffi x V or W that are designed for AC service and
normally closed operation are for use with No. 2 and 4 fuel oil
service. These valves have the same maximum temperatures per
the above table except Suffi x W valves are limited to a maximum
fl uid temperature of 140ºF.
Listed below are valves with Suffi x V in the catalog number that
are acceptable for higher temperatures.
*The only exception is the 8262G and 8263G series (Class F coil)
at 50 Hertz rated 11.1 and 17.1 watts are limited to 210_F fl uid
temperature.

Positioning

This valve is designed to perform properly when mounted in any
position. However, for optimum life and performance, the solenoid
should be mounted vertically and upright to reduce the possibility
of foreign matter accumulating in the solenoid base sub-assembly
area. Valves with suffi x "P" in the catalog number must be mounted
with the solenoid vertical and upright.
