KOFLOC 2204
The KOFLOC Variable Primary Pressure Flow Controller MODEL 2204 SERIES is a control valve for precise control of minute gas flow and maintaining constant flow under fluctuating primary pressure (inlet), provided the secondary (outlet) pressure remains constant. This characteristic makes it a must-have preliminary valve in many flow control mechanisms. Constructed using high precision parts, the design of the MODEL 2204 SERIES transforms the rotation of the regulating screw to into linear motion of the needle without subjecting it to gaps and vibrations produced by the screw, to ensure stable and even control of minute flow.
FEATURES
♦ Excellent flow stabilization
♦ Clean construction
♦ Independent from supply pressure fluctuations
APPLICATIONS
♦ Scientific instruments
♦ Environmental analysis
♦ Atomic absorption spectrometry
♦ Gas chromatography
♦ R&D
♦ General industrial use

The Model 6N Needle Valves have been designed to give higher strength and integrity to instrument needle valves. Budenberg have incorporated a dynamic multi-ring gland system in the needle valve, which when combined with the anti blow-out back seating stem, guarantees resistance to all operating processes and pressures.
Low operating torques and high cycle life feature strongly in this unique Budenberg design, giving a "Low Cost of Ownership".
Key Benefits are:
Guaranteed Sealing with the minimum effort.
Over designed high strength adaptor threads combine with soft' parent metal bottom seal to give closure thread protection and ensures environmental safety.
Gland and stem leakage is a thing of the past due to the dynamic multi-ring gland system, combined with the anti blow-out back seating system
Swaged self centering non-rotating Duplex stem ensures. point positive seat closure under all conditions.

ASCO/JOUCOMATIC has developed a wide range of valves for all fluids, whether neutral or aggressive, made out of brass, bronze, cast iron or 316L stainless steel.
Reliability is ensured by:
* A monobloc rod, with stainless steel from the reed to the piston
* Guidance by 2 extra-large PTFE bearings.
Pilot solutions: solenoid valves on valves or mounted on subbases and valve islands.

This type of valve is actuated by pressure acting on a piston or diaphragm. The fluid is usually neutral e.g. air, water, hydraulic oil. The pressure range varies and is specified accordingly in a data table.
"Normally Closed" (N/C) valves of this type remain closed under spring pressure, when de-activated.
"Normally Open" (N/O) valves of this type remain open under spring pressure, when de-activated.
When pressure is connected to port "Z" the valves open or close according to type.
A separate 3/2 pilot valve is used to supply pressure to port "Z", it is mounted either directly on the actuator or remotely.
In some cases a 4/2 or 5/2 pilot valve will be required. The main valve position can be N/C or N/O. The basic position is determined by connecting the pilot valve output lines accordingly. (The direction of flow is usually indicated by an arrow or shown schematically on the body).

Technical details of Type 63:
2/2-Way pressure controlled valve
Body: RG-5, Brass, Stainless Steel
Sealing: NBR, FKM, PTFE, EPDM
Connection: G3/8-G3
Pressure range: 0-40 bar
Pressure controlled valves have a simple and sturdy design and therefore they are suitable for nearly all media up to a viscosity of 600 mm²/s. Additionally, they are immune to particles in the media. These valves are also chemical and thermal resistant because of there design. Together with a small ATEX approved control valve these valves are also suitable in hazardous areas.
Application fileds for pressure controlled valves are, for example:
- Filling systems
- Brewing equipment
- Chemical systems
- Mixing systems
- Food processing industry
- Concrete and cement industry
- Vacuum equipment
- Water treatment
- Pneumatics
Extras for pressure controlled valves are, for example:
- visual settings display
- electric indication
- manual operation
- free of oil and grease
- vacuum design
- vacuum and pressure design
- double acting actuator
- free of nonferrous heavy metal
- flanges according to ANSI
- temperatures up to +300°C
- higher pressure ranges
