DECON offer a comprehensive range of tube fittings that are designed and developed for advantages such as leak proof,
torque free sealing at tubing connections and reduction of costly hazardous leaks in instrumentation and process
tubing.
Some of the salient features of our tube fittings include the following:
Tube fittings have four part components including nut, back ferrule, front ferrule and body. When installed it offers
a five piece connection on fixing to tubing. The tube fittings function by moving along the tube axially instead of
with a rotary motion. As there is no torque transmission from the fitting to the tubing and no initial strain, there
is no weakening of the tubing.
The ferrule design and sequential action of the fitting eliminates the influence of the tube material, wall thickness
and hardness to ensure safe, reliable and leak proof connections. Tube fittings are easily installed and no special
tools required.
The 1-1/4 turn on the nut from the hand tight position assures consistent drive of the sealing members. This ensures
an effective seal against high pressure as well as ultra high vacuum conditions.
Available in tube sizes from 1/16 to 2 in. and 2 to 50 mm.
Easy to disconnect and retighten.
Wide variety of materials and configurations.

DECON Instrument Thread Fittings have been developed based on ASME B31.3 for instrumentation and process control in
size 1/8" to 2." DECON Thread & Weld fittings have wrench flat allowing standard Hex wrench assembly. This is one
of the DECON Pipe fitting benefits.
Attractive finishes to suit precision equipment.
Space-saving (therefore less-weight design).
Each fitting is cleaned to eliminate system contamination.
Fine NPT pipe thread construction equal or exceeds the requirement of ASME B1.20.1 to ensure maximum thread
engagment.
Service at greater pressure levels than the traditional class 3000pipe fitting to ASME B16.11.
Male pipe threads are capped to be protected from damages.
316 stainless steel is standard material, other materials are available upon request.

DECON weld Fittings are designed in accordance with ASME B16.11 and provide tube socket welding, pipe socket welding,
tube butt welding, and pipe butt welding connections.
All DECON weld tube socket ports have a tapered sizing angle at the end that holds tubing properly and provides
approx. 1.5mm(0.08") welding gap recommended by ASME B16.11. This feature allows consistent welding assembly as well
as pre-assembly of many tubing runs before welding.

DECON also offer multiport gauge valves using best quality raw materials. Some of the salient features of our gauge
valves encompass the following:
Our block gauge valve and bleed gauge valve is designed to provide safe, compact and economical gauge installation.
Our valves enable safe relieving of pressure without breaking threaded connections.
DECON manifolds have excellent flow regulation and leak tightness. The operation is smooth, easy, low-torque & long
life. Internal surfaces & threads are 100% free from burrs & other foreign particles .Many of the options available
with needle valves are available in manifold form. Complete Bonnet assembly will be similar to needle valves.
Manifold valves have stainless steel color coded identity tags affixed to the individual head units, Red for Isolate,
Green for Equalize and Yellow for Vent. Manifolds have plugs as standard on gauge valves only, for all others this
is optional. End connections are ½” NPT(F) & pressure rating is 6000 PSI as standard.
All direct mount manifolds are supplied with Teflon gaskets and high tensile carbon steel bolts. Grafoil gaskets and
stainless steel bolts are as optional.
All valves can be made available to conform to NACE MR-01-75 (latest revision) for sour service. Multiple mounting
hole options are available on request. Universal mounting bracket fits most manifolds, plus other options are
available.

Accurate flow measurement is of primary importance in achieving an efficient process system. DECON offers Forged or
Bar Stock Double Needle Valves designed to provide accurate, safe and dependable flow measurement. The design of
these valves reflects extensive engineering and manufacturing experience, resulting in attainment of the highest
standards for valve quality and reliability.
DECON Double Needle Valves have been engineered to provide versatility in meeting specific process requirements.
Several standard bonnet assemblies offer different stem, seal and material selections. Most valves are rated for
pressure service to 6,000 psi (414 bar) with certain models rated to 10,000 psi (690 bar).
One piece Forged or bar stock construction with two needle valves and full material traceability.
Back seating of stems in a fully open position prevents stem backout.
All valves are designed in accordance with ASME/ANSI B16.34 and ASME Section VIII, Div. 1.
Body construction: Forged or cold drawn bar.
Body materials: 316 SS, 316L SS, 304 SS, 321 SS and F91.

The main purpose of condensate pot is to catch and hold condensate and foreign material. This prevents damage to the
metering system and/or manifold. The condensate may be drained from the bottom valve connection. OS&Y gate or ball
valves to be used as the drain port.
Condensate chambers are used as a barrier between the main line and the secondary instruments in the measurement of
steam or other vapors which condense to a liquid state insuring compatibility with the secondary instruments. They
can also be used to cool down very high temperature liquids. Seal pots are installed where the line fluid is
corrosive or viscous to the extent where it cannot be permitted to contact the secondary instrument. (transmitter or
gauge) thereby acting as a liquid barrier between the line fluid and the condensate.

Wide choice of standard modular components helps you meet application requirements more exactly without the added
costs of a custom system.
High Pressure Lubricators provide true modularity that permits customizing a pump-to-point lubrication system from
off-shelf components. The modular variables consist of the following categories of components:
Pumps
Reservoir
Reservoir Heaters
Reservoir Oil Level Controls
Drives
Shaft Rotation Alarm
Motor and Motor Mounting Bases.
In addition to these High Pressure Lubricator components, DECON offers a complete line of auxiliary equipment. Also,
the pumping packages can be used with divider valves in a series progressive installation.
DECON High-Pressure Needle Valves have excellent flow regulation and leak tightness. The operation is smooth, easy,
low-torque & long life. Internal surfaces & threads are 100% free from burrs & other foreign particles. DECON offers
Valves with Non-Rotating Tip Stem (NRT) thereby providing tight, repeatable shutoff without the galling or
cross-scoring that occurs on V & ball-type stems. The NRT conical stem tip stops rotating when it contacts the seat
so that any further torque turns the stem and not the tip.
Pressure Rating:PTFE: 6,000 PSI & High Pressure up to 10,000 PSI; GRAPHITE: 10,000 PSI;
