Manual Operators are provided to operate the valve manually when electrical power is off.
There are basically two types of manual operators:
  1. Momentary
  2. Maintained

Series 8320 and 8321 can be fitted with either type.
To determine which type is available for your valves, check the Construction Reference Number in their Series Specification Tables against the Manual Operator Table. Schematics of the manual operators and how they are fitted to the valves are shown.
Add suffix "MO" or "MS" to the catalog number.

 

Metering Devices are used for obtaining an exact flow from a solenoid valve for dispensing, or for moving an air operator in a given time period.
Valves which can be fitted with metering devices are Series 8262 (¹/8" N.P.T. size only), 8260, 8401, 8402 and 8342. Add suffix "M" to catalog numbers.

 

Special Cleaning and Testing Procedures: If special cleaning and testing procedures are required, they should be specified on the order as indicated below.
Note: These procedures cannot be done after the valve is built.

ASCO Special Cleaning and Testing Procedures
Fluid Description of Cleaning or Testing Procedure Order by Specifying
Freon All valve parts inspected for oil, grease, metal dust and other foreign
matter and degreased, if necessary. Assembled in clean, dry area and
helium mass spectrometer tested for external leakage. Pipe connections
sealed with plugs.

The construction materials for standard valves are shown in the Specifications Table for the series of valve. See the ASCO Valve Material Selection Guide for a variety of liquids and gases other than air, inert gas, water and light oil. A solenoid valve must use certain construction materials for proper electrical function.
Certain fluids may also require that we change the solenoid shading coil. The standard valves use a copper shading coil. Aluminum and silver are also available and, due to their different magnetic properties, additional electrical changes may be necessary.
This table shows the elastomers available for the various valve Series numbers. Construction references are shown in the Specification Table for each valve series.
