Asco 8262 series Installation & Maintenance Instructions

Installation & Maintenance Instructions
NORMALLY OPEN OR NORMALLY CLOSED OPERATION
BRASS OR STAINLESS STEEL CONSTRUCTION - 1/8 , 1/4 , OR 3/8 PIPE THREADS
IMPORTANT: See separate solenoid installation and maintenance
instructions for information on: Wiring, Solenoid Temperature,
Causes of Improper Operation, and Coil or Solenoid Replacement.

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.
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 energized.
Normally Closed: Valve is closed when solenoid is de-energized;
open when energized.
IMPORTANT: No minimum operating pressure required.
Manual Operation (Valves with Suffi x 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
90º 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 the solenoid is energized. To disengage,rotate stem
counterclockwise until it hits a stop, approximately 90º 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 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 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 "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
fl uid after disassembly and reassembly.

Temperature Limitations

For maximum valve ambient and fl uid temperatures, refer to the
following tables. Use catalog number, coil prefi x, suffi x,and watt rating
on nameplate to identify the maximum ambient and fl uid temperatures.
