PTFE CHECK VALVES

PTFE CHECK VALVES

NACOMS PTFE CHECK VALVES

NACOMS PTFE CHECK VALVES are designed for use where a valve inert to corrosive fluids of varying viscosities  is required . Further they are designed with all wetted surfaces fabricated from virgin PTFE to meet tough requirements in the chemical microelectronic and petroleum industries.

1/8" thru 1/2" diameter SIZES

Nacom's PTFE CHECK VALVES are available in sizes starting at 1/8" dia and going up to 1/2" dia . End connections include FNPT, Compression Tube, and Flared

ALL PTFE WETTED SURFACES

NACOM'S standard PTFE CHECK VALVES have all wetted PTFE Surfaces.

Body - PTFE

Cap- PTFE

Poppet  - PTFE

Diffuser - PTFE 

Spring - PTFE

Nut- Polypropylene *


*Can be substituted with PVDF or PTFE

MIX MATCH PORTS

NACOMS PTFE CHECK VALVES are usually equipped with matching inlet and outlet ports as a standard feature .

Example : NA CV 1300 is a 1/4" fnpt PTFE Check Valve with 1/4" FNPT inlet & outlet ports.


Mix Match  is where the inlet port and outlet port are different. Example 1/4" FNPT inlet with a 1/4" MNPT outlet 

Part number is NA CV 1300/01   

HIGHER CRACKING PRESSURES

NACOMS PTFE CHECK VALVES Have a cracking pressure of 1 psi . To acheive higher cracking pressures we suggest using a oring embedded ptfe poppet. (usually viton or kalrez) and replacing the PTFE Spring with a TFE coated stainless steel spring.  This only applies to valves requiring hire cracking pressures
