2.3 Pressure/temperature limits -
DP17, DP17G, DP17R, DP17Y and DP27G
The product must not be used in this region.
A-D-E Screwed and flanged BS 4504 PN25, ANSI 300, and BS 10 Table H.
A-B-C Flanged ANSI 150.
F-F The DP17G and DP27G are limited to 120 °C.
Note: DP17, DP17G and DP27G have a variable rate conical pressure adjustable spring
fitted providing a downstream pressure range of 0.2 - 17 bar g.
DP17Y has a pressure spring with a range of 0.2 - 3 bar g.
DP17R Maximum downstream reduced pressure 15 bar g. The control pressure
signal to the pilot diaphragm must be approximately 0.7 bar above the required
reduced downstream pressure.
