SIGHT GLASSES - SLSG SERIES
Australian Pipeline Valve - Installation, Operation and Maintenance Manual2
INTRODUCTION
The majority of this information is common knowledge to experienced valve users. When properly
installed in applications for which they were designed, Flowturn valves will give long reliable service.
This instruction is only a guide for installation and operation on standard service and covers general
maintenance and minor repairs. A professional APV approved valve engineering facility should be utilised
for reconditioning or major repairs.
Note
We do recommend however that this entire document be read prior to proceeding
with any installation or repair. Australian Pipeline Valve and it’s parent company
take no responsibility for damage or injury to people, property or equipment. It is
the sole responsibility of the user to ensure only specially trained valve repair
experts perform repairs under the supervision of a qualified supervisor.
RESPONSIBILITY FOR SIGHT GLASS APPLICATION
The User is responsible for ordering the correct valves. The user is responsible for ensuring APV-Flowturn
Valves are selected and installed in conformance with the current pressure rating and design temperature
requirements. Prior to installation, the valves and nameplates should be checked for proper identification
to ensure the valve is of the proper type, material and is of a suitable pressure class and temperature
rating to satisfy the requirements of the service application.
Do not use sight glasses in applications where either the pressure or temperature is
higher than the allowable working values. Also sight glasses should not be used in
service media if not compatible with the sight glass material of construction, as this
will cause chemical attacks, leakage, valve failure.
RECEIVING INSPECTION AND HANDLING
Valves should be inspected upon receipt to ensure:
- Conformance with all purchase order requirements.
- Correct type, pressure class, size, body and trim materials and end connections.
- Any damage caused during shipping and handling to end connections, hand wheel or stem.
The User is advised that specifying an incorrect valve for the application may result
in injuries or property damage. Selecting the correct valve type, rating, material
and connections, in conformance with the required performance requirements is
important for proper application and is the sole responsibility of the user.
