Care should be taken to select the most suitable steel valve for your service(s). Exact specification of each valve should be made to avoid ambiguity when requesting quotations or ordering the product.
Size
Nominal size of the pipeline into which the valve will be placed must be determined. Comprehensive data on flow characteristic and pipe properties are contained in the Engineering Data Catalog
Valve Material
The following facts should be considered in determining the correct valve material.
1.       The media to be controlled
2.       The temperature of the media
3.       The possible extraordinary stresses affecting the valve
4.       Safety standards and/or piping codes
Type of Valve
A few minutes spent in reading some simple valve facts will prove helpful.
Pressure/Temperature Rating
Please pay careful attention that the PRESSURE/TEMPERATURE RATINGS ith the requirements of the service
Valve End Connections
Considerations as to pipeline integrity, future maintenance, corrosion factors, field assembly, weight and safety should be given in determining the method of connecting the valve in the pipeline
Ordering Information
