CleanFLOW Valves

Seats
CleanFLOW^TM ball valves feature high-performance TFM seat material as standard. TFM is chemically modified PTFE that fills the gap between conventional PTFE and melt-processable PFA. Compared to conventional PTFE, TFM, has the following enhanced properties: Much lower deformation under pressure (cold flow) at room and elevated temperatures. Lower permeability. May be used at higher pressures. Our seat specification reads as follows:

Seats - PTFE - TFM, (FDA, USP23 Class VI), Non-slotted, designed to meet ASME/BPE SD 3.6.1, SG4.1.1.8, SG4.1.1.6.

Body Seals
CleanFLOW^TM encapsulated PTFE seal design eliminates possible entrapment area between valve body and ends, also facilitates inline welding without disassembly. Optional body seal material is available when required.

Cv Factors For
CleanFLOW^TM Ball Valves

Size	Port	Cv	Size	Port	Cv
1/2	.37	8	2	1.87	434
3/4	.62	29	2-1/2	2.37	723
1	.87	66	3	2.87	1124
1-1/2	1.37	192	4	3.83	2100

Cv is defined as the number of U.S. gallons per minute that water will flow thorough a valve at 1 p.s.i drop.

*Pressure Rating

CleanFLOW valves may be used at higher pressures and temperatures using either NRG or PEEK seats. Please consult factory for exact specifications.

Vacuum Rating
CleanFLOW valves provide excellent performance under vacuum conditions and have been helium leak tested to 1 x 10-9.
