Introduction
CFIA filters are a range of angle-way and straight-way filters which are carefully
designed to give favourable flow conditions.
The design makes the filter easy to install, and ensures quick filter inspection
and cleaning.
CFIA filters are used ahead of automatic controls, pumps,compressors etc.
for initial plant start-up and where permanent filtration of the refrigerant is required.
The filter reduces the risk of undesirable system breakdowns and reduces wear
and tear on plant components.
CFIA filters are equipped with a screen mesh of stainless steel, available in sizes
100, 150, 250 and 500 (microns*), (US 150, 100, 72, 38 mesh*).

Design Connections
Available with the following connections:
  • Butt-weld ANSI (B 36.10 Schedule 80),
        DN 15 - 40 (1/2 - 11/2 in.)
  • Butt-weld ANSI (B 36.10 Schedule 40),
        DN 50 - 200 (2 - 8 in.)
  • Socket Weld (ANSI B 16.11), DN 15 - DN 40 ( -1. in.)
Filter Insert
A filter grid and filter net of stainless steel ensure long element life.
The filter net offers a very high degree of cleanability.

Strainers, type CFA-AV,CFA-ST
Liquid Level Indicator
Application : These level indicators are used to display the level of
ammonia gas in the system.

Material of construction : Valves are made of steel with a ball for
protection incase of failure. The glass is fused to the metal at
high temperatures.

CREG are angle-way and straight-way regulating valves, which act as normal stop valves in closed position.
The valves are designed to meet the strict quality requirements on refrigerating installations and are carefully
designed to present favourable flow conditions and accurate linear characteristics.                                           

CREG are equipped with internal backseating enabling the spindle seal to be
replaced with the valve still under pressure.
Features
  • Applicable to all common non flammable    
        refrigerants including R 717 and non corrosive \       
        gases / liquids dependent to sealing  material
        compatibility
  • Designed to ensure perfect regulation
  • Internal backseating enables replacement of
        the spindle seal whilst the valve is active, i.e.
        under pressure
  • Easy to disassemble for inspection and
        possible repair
  • Max. operating pressure: CREG: 40 bar g  (580 psi    
        g) Full temperature range packing gland - 46 /    
        +150C

Ball valves
Regulating Valves, type CREG-AV, CREG-ST
Application
These valves are for Ammonia duty. The MSVA are pilot operated valves whilst the
MDSVA are direct operated solenoid valves.
They are used in many applications such as cold stores, freezers, chilling applications etc.

Construction
The valve is made up from various metals. Whilst stainless steel is used for
components like stems, plungers, the main body is made from  LCC

Safe  Working  Pressure : 300 psi
Solenoid Valves
Liquid Level Controller and Liquid Level Switch
Stop Needle Valves, type,-CSNVA-ST
Application
While primarily designed for Ammonia, this  control is also suitable
for R-22 and other non-corrosive liquids
that have a specific gravity of  0.5 or more.
The controller is ideal for the control of the operating level of liquid
in liquid refrigerant accumulators and separators.
Although this is normally done with a solenoid valve, the controller
can activate an
alarm or a pump or similar device.

Safe  Working  Pressure : 300 psi
SZ-FR-2000 Fruit Ripening Controller
T72 - 4" Dial Tempreture Indicator
Features :
  • Applicable to all common refrigerants including R717 and     
        R744 (CO2) and non corrosive gases/liquids.
  • Suitable for "heavy duty" industrial applications having a very    
        sturdy and safe design including high pressures and wide
        temperature range.
  • The SNV-ST  valves have backseating (metal to metal).
        Compact and light valve for easy handling and installation
  • No special flow direction required.
  • Provide high flow characteristics.
  • Each valve type is clearly marked with type and size.
  • Housing and bonnet material is low temperature steel         
        according to requirements of the Pressure Equipment
        Directive and other international classification authorities.
  • Valve safety is enhanced with the spindle being secured such
        that it cannot be unscrewed.
  • Max. operating pressure: 52 bar g ( 754 psig)
  • Full temperature range: - 46 +150C
Design :
Connections
    Available with the following connections:
    CD Cutting ring
    MPT Male NPT ANSI
    FPT Female NPT ANSI
    G
    W Welding connection

Housing
Made of special steel, approved for low temperature operations.
SZ7510 P - Tempreture Controller with power switch
Ball Valves - DN 15 to DN-125 (1/2" to 5")
Application
Petroleum, Petrochemical, Chemical, Refrigeration, airconditioning and engineering industries.
Valves are compatible with Ammonia, CFC, HCFC, Oil, Air, Chemicals, Gas, Acids, Alkalies etc.
amongst many other media.

Installation
The three piece design makes the Series C-44 valves the most easily maintainable valves in
its type.
By removing three body connetor bolts and loosening the fourth,
the body can be swung away using the fourth bolts as a fulcrum,  to carry out any
maintanance on the valve.
This feature allows the valve to be online and considerably reduces down time.

SWP : 40 bar                    Temp : -46/+125°C
Purge valves with counterweights
DN-8 & DN-15
Design characteristics
Purge valves with counterweights are valves with a normal primary closing
system and a secondary closing system operated by the counterweight
falling.The normal closing system is designed to provide a seal for a long
period.The secondary closing system is a quick but provisional closing,see
below the design working pressures.
