12 END CONNECTIONS/DRAINABILITY<br />
END CONNNECTIONS<br />
<strong>Pure</strong>-Flo Diaphragm Valve bodies are available in a<br />
variety of end connections:<br />
• Tri-Clover Tri-Clamp ®<br />
• Cherry Burrell “S”, “Q”<br />
and “I” line ®<br />
• 14, 16, 18, 20 O.D.<br />
Gauge Tubing<br />
• Schedule 5, 10, 40 Piping<br />
• ISO Ends<br />
• SMS 1146 Ends<br />
• DIN 11850 Ends<br />
• Others upon Request<br />
Standard cutback is 1/2" (1.27 cm) unless otherwise<br />
specified. Maximum cutbacks range up to 1.25" (3.17<br />
cm), dependent upon valve size, and are available<br />
upon request. In addition, tube end extensions of 1.5"<br />
are available to accommodate automatic welding. ISO<br />
ends standard cutback is longer in length and ranges<br />
from 25 mm–35 mm dependent on valve size.<br />
DRAINABILITY<br />
Drain marks are provided as standard on cast and<br />
forged bodies to facilitate installation and optimize<br />
drainability. One mark must be located in the vertical<br />
plane, cutting the centerline of the pipe. Refer to the<br />
General Engineering Data section, page 73, for drain<br />
angles.<br />
The slope of process piping must be designed to provide<br />
proper pitch in order to optimize drainability.<br />
Drainability in a process system is ultimately the<br />
responsibility of the system designer and/or end user.<br />
