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

watertight/explosionproof solenoid enclosure.

OPERATION

Normally Open: Valve is open when solenoid is de--- energized;

closed when energized.

Normally Closed: Valve is closed when solenoid is de---energized;

open when energized.

IMPORTANT: No minimum operating pressure required.

Manual Operation (Valves with Suffix MS)

Manual operator allows manual operation when desired or during

an electrical power outage.

To engage manual operator, rotate stem on the side of the body

clockwise until it hits a stop, approximately 90_ from its original

position. Do NOT rotate beyond stops. Do NOT apply excessive

force beyond stops. Valve will now be in the same position as when

thesolenoidis energized. To disengage,rotate stem counterclockwise

until it hits a stop, approximately 90_ from its original position. Do

NOT rotate beyond stops. Do NOT apply excessive force beyond

stops.

MS option is not available on normally closed valves that have a

pressure rating greater than 750 PSI. MS option is not available on

normally open valves.

CAUTION: Do NOT rotate beyond 90

stops. Do NOT apply

excessive force beyond stops. Rotating beyond the 90

stops could

result in equipment damage.

CAUTION: For valve to operate electrically, manual operator

stem must be fully rotated counterclockwise.

INSTALLATION

Check nameplate for correct catalog number, pressure, voltage,

frequency, and service. Never apply incompatible fluids or exceed

pressure rating of the valve. Installation and valve maintenance to

be performed by qualified personnel.

Note: Inlet port will either be marked “1” or “IN”. Outlet port will

be marked “2” or “OUT”. (see Figure 1)

Future Service Considerations.

Provision should be made for performing seat leakage, external

leakage, and operational tests on the valve with a

nonhazardous,noncombustible fluid after disassembly and

reassembly.

Temperature Limitations

For maximum valve ambient and fluid temperatures, refer to the

following tables. Use catalog number, coil prefix, suffix, and watt

rating on nameplate to identify the maximum ambient and fluid

temperatures.

NOTE: The following Temperature Limitations Tables do not

apply to Magnetic Latch Valves: Catalog Numbers 8262A610 to

8262A627; 8263A615 to 8263A618, and 8263A624 to 8263A627.

Positioning Valve Disassembly (see Figures 2, 3 & 4) These valves are 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. Mounting Two (2) M5 threaded holes are provided in the valve body for mounting.
