Steam traps Ball float
8
Sizes and pipe connections DN15, DN20, DN25, DN40 and DN50. Note: Flow direction, for horizontal orientated traps, when facing the body:
- DN15 to DN25 is left to right. - DN40 and DN50 is right to left. For vertically orientated traps the flow is downwards only. Standard flanges are EN 1092 PN40 with face-to-face dimensions in accordance with EN 26554 (Series 1). On request ASME B 16.5 Class 150 flanges are also available with face-to-face dimensions in accordance with EN 26554 (Series 1). ASME flanges are supplied with tapped (UNC) holes for flanged bolts.
