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 necessay. Assembled in clean, dry area and helium mass spectrometer tested for external leakage. Pipe connections sealed with plugs.	Clean and test per ASCO AP-1-005 Procedure
Oxygen	All valve parts degreased and "Blacklight" inspected for cleanliness. Assembled and tested in clean area using oil-free air or nitrogen. Helium mass spectrometer tested for external leakage. Pipe connections sealed with plugs. Each valve tagged covering certification of tests and put in a sealed bag.	Clean and test per ASCO AP-1-004 Procedure Add suffix "N" to catalog number.
Sanitary distilled water and other clean systems	All valve parts inspected for oil, grease, metal, dust, and other foreign matter and degreased, if necessary. Valves assembled in clean area and tested with clean, dry air or nitrogen. Pipe connections sealed with plugs.	Clean and test per ASCO AP-1-008 Procedure

Notes: For valves requiring special cleaning and/or testing procedures such as for oxygen, freon and sanitary service, refer to Special Cleaning and Testing Procedures Table above. Pressure ratings must be reduced by 25% Not available for valves with low pressure (1.5 - 5 psi) operator. Unless otherwise indicated in the Series Specifications Tables, all soft seating valves are supplied with Buna "N" discs, diaphragms or gaskets.

     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.
