MOMENTUM
Momentum is a funny thing... The more you use it, the more you generate it.
NACOM has had a ton of momentum behind our ideas. We strive to make our ideas turn into reality. When others tell you NO, WE MAKE IT HAPPEN
STANDARD OR CUSTOMIZED
NACOM manufactures many products with standard configurations. However there are times when you need a special configuration or making one valve become a multivalve manifold. Standard or Custom configurations or designs is what we do.

NUT TYPES
NACOM'S COMPRESSION FITTINGS can be ordered with the following nut types on compression tube fittings.
The "HA" type is our standard nut type that we put on our PTFE fittings. This nut uses a PTFE Ferrule with a Kynar Gripper set up . As the nut tightens the Kynar gripper's "teeth" grab the tubing and tighten its grip on the tubing and does not allow tubing to pull out .
All standard HA style nuts have a teflon ferrule with a kynar gripper included.
HA style nuts are fabricated with Solef PVDF resin when they are injection molded.
HA - HA indicates this type of nut is injection molded PVDF with PTFE Ferrule, and Kynar gripper
TA- TA indicates this type of nut is a machined PTFE Nut with a anodized aluminum band support. TA style nuts use a single sleeve PTFE Snap in ferrule. no gripper
TS- TS indicates this type of nut is a machined PTFE Nut with a stainless steel band support. TS style nuts use a single sleeve PTFE Snap in ferrule. no gripper
TA and TS NUTS ARE A SPECIAL ORDER

TEFLON PRESSURE REGULATOR
Nacom's PTFE PRESSURE REGULATOR with all wetted parts of virgin teflonfor surpassed corrosion resistant and ultra pure properties in fluid and gas handling applications.
Nacom's TEFLON PRESSURE REGULATOR does an excellent job of reducing upstream pressures to a predetermined downstream pressure.
Fluid entering the Regulator flows through the orifice where it is throttled by the poppet and continues through to the outlet port. This pressure regulated fluid also passes through a bleed and acts as a sensing diaphragm to balance the force of the adjustment spring. The poppet tracks the movement of the diaphragm providing the proper throttle position at the orifice to maintain desired downstream pressure. The leak tight seal assures bubble tight closure in the no flow position.

REBUILDABLE VALVE
NACOM's ACR Valves are 100% tested for actuator open and close performance and fluid flow through the valve, then a pressurized leak detection test. Our valves are guaranteed to meet product specifications. When the ACR Valve is installed and plumbed correctly the valve will operate without any issues. When the fluid running through the valve is not filtered prior to entering the valve , loose debris such as broken chips may cause the valve to start leaking due to seat damage to the valve or valve in manifold. Should this occur simply remove 4 screws from baseplate on lower portion of valve. Pull pneumatic housing off, replace Teflon bellows if needed and replace outlet port. tighten back up and your good to go. NO MORE HAVING TO BUY A NEW VALVE
