FEMA is present since 1959 on the Italian and foreign markets and achieved a high
specialization in designing and manufacturing valves for cryogenic systems.
In the latter years, FEMA introduced a wide range of safety valves in their own production,
based on the same manufacturing technique, to meet the ever increasing needs of the modern
plant engineering technique.
FEMA CAT01
Rev. 8
Page 3
GENERAL
The FEMA’s safety valves are spring-loaded valves designed to operate with liquid, gases, and
vapors, and are designed in accordance with the API 526 standard.
With regard to Directive 97/23/CE (PED)., the valves have been classified into category IV and
qualified by the Notified Organization “Società Consortile PASCAL N° 1115 “ Via A. Scarsellini, 13
– 20161 Milan (Italy) in accordance with the conformity evaluation procedure module B + D and
conform to the basic safety requirements specified in attachment 1 thereto.
With regard to Directive 94/9/CE (ATEX), the valves have been specified in Apparatuses Group II,
Cat. 2G.
For the valves of series 3000 and 3100 - 3400: full-rate opening: +10%, closing deviation: –10%;
for the valves of the series 2000, full-rate opening: +5%, closing deviation: -12%.
For a valve installed on a process plant, the operating pressure shall never exceed 85% of the
calibration pressure.
Nozzles are characterized by pressure and flow. The valve lift is controlled by a thrust ring.
The bodies are obtained from high-quality castings and controlled through the most appropriate
non-disruptive inspection methods. Carefully lapped surfaces assure valve sealing.
The springs are engineered in such a way as to get the best stress status over the operating range
in the elastic state.
Standard materials and components are used in manufacturing the valves, in order to assure
safety and make maintenance operation easier.
The static and dynamic behavior of the valves is evaluated theoretically and tested experimentally
in qualified laboratories under the surveillance of certified inspection organizations.
Thanks to the measures described above, the FEMA safety valves feature high discharge
coefficients.
The FEMA safety valves are engineered and classified according to the series listed below:

RISK FACTORS
The use of safety valves unavoidably implies risk factors, which are basically related to their operating
conditions.
The valve-related risks, and particularly those related to valve configuration, are carefully considered
when designing them, on the basis of the current regulations, without introducing significant
innovations. Specifically:
Configuration: Reference is made to the configurations specified in the API 520 and ASME
B16.34 and ASME B16.5 Standards. Also, their drawing is particularly simple,
so as to make it easier to operate, maintain, mount, and control the valves.
Manufacturing methods: the manufacturing methods are fully consolidated and don’t present
any risk or uncertainty factor. Their manufacturing technology is
used at Fema for many years, and nothing unknown is associated
therewith.
Tests:
Tests on materials and production, particularly during the mounting phase, as
specified by company procedures, assure quality of the products and compliance
with the applicable requirements.
Materials: The materials used conform to the ASME B 16.34 reference standards.
Operating product analysis: So far, no significant malfunctions have been reported on the
valves produced by Fema over 50 years of activity.
Installation-related risks
The safety valves installation modes are correctly described in the instruction manual and conform to
simple safety and operativeness criteria according to the provisions of the API 520, part 2nd standard.
Use-related risks
The use of the safety valves of the types manufactured by FEMA is conditional on knowing them, their
operating principles, and their mode of use in complex systems and apparatuses.
Consequently, the use of the valves shall be committed to expert and skilled personnel only.
Further potential risks resulting from:
valve abnormalities or malfunctions
their installation
their use
are described in the instruction manual.

DESCRIPTION
Figure 1 shows the basic configuration of the safety valves.
This figure identifies the individual zones with their specific structural and functional characteristics.
The function performed by the high-pressure zone, which is in direct contact with the underpressure part of the plant, is to contain the fluid until this one goes beyond the valve’s set value.
This zone comprises the following component parts:
Nozzle
Disc
Valve body inlet flange
Perfectly flat and carefully lapped metal surfaces assure the disc’s sealing.
Wherever necessary, the contact surface is hardened by a deposit of stellite, which is subsequently
also submitted to a lapping process to get a perfect sealing.
The low-pressure zone basically consists of fluid discharge ducts.
Finally, there is a control zone, separated by the low-pressure zone by containment devices or
sealing devices, where a contrast spring, an adjusting screw, etc. are accommodated.

MECHANICAL CHARACTERISTICS
EXTERNAL STRUCTURE
A BODY, a BONNET, and a CAP are the component parts and consist of high-quality castings.
BODY:
It’s the most important part of the structure and its function is to accommodate the component parts
of the discharge and closing mechanism.
It is submitted to an hydraulic test at the discharge rating pressure. Upon a customer's request, a
pneumatic pressure test and a radiographic test are also carried out.
The body thicknesses are in accordance with the ASME/ANSI standard B16.34.
The connection flanges are machined and engineered according to the ASME/ANSI B16.5 – UNIDIN standards.
BONNET:
It's the main part of the structure and is available in two construction options: open or closed.
Its function is to accommodate and protect the spring and the guide stem.
A calibration screw is screwed-in on its top section.
CAP:
It’s the terminal part of the structure and is available in the following options: standard, with simple
lifting lever, with packet lifting lever.
A threaded hole is located on its upper side to accommodate a gag, which is normally closed by a
screwed-in plug.
Its function is to protect the adjusting screw from tampering.
FEMA CAT01
Rev. 8
Page 14
BODY’S INTERNAL COMPONENT PARTS
NOZZLE:
It’s a full-nosepiece nozzle, made of ASTM A 479 Tp. 304 – 316 with forged and pressed material
for orifices D - P, or cast material for orifices Q, R, T.
The upper terminal part makes-up the disc seat and is of the mechanically-hardened flat type or
(on request) stellited.
The nozzle is optically tested with interference fringes after being submitted to lapping.
The nozzle is screwed in the lower body’s section and is constantly in contact with the process
fluid.
DISC:
It is a one-piece disc according to ASTM A 479 Tp. 304-316 and features a grinded and lapped
sealing surface; if requested, the seat might be stellited.
The disc is freely coupled to the disc-holder by a ball joint and a spring ring. Its function is to stop or
make the process fluid flow.

DISC-HOLDER:
It’s manufactured according to ASTM A 479 Tp 304-316 with a rolled material for orifices D - G,
and forged and pressed material for orifices J - P, or cast material for orifices Q, R, T.
In its upper side, it is coupled with the spring guiding stem by a ball joint.
FEMA CAT01
Rev. 8
Page 15
GUIDE:
Its length is not less than 2.5 times its inner diameter and is blocked in a flange, which is enclosed
between the body and the bonnet, and its function is to guide the disc-holder.
BLOWDOWN RING:
The blowdown ring is used in conjunction with compressible fluids (gases and vapors) and its
function is to regulate the valve's closing and to prevent its seat from pounding-in.
It is screwed in the nozzle with a fine-pitch threading and comprises a peripheral indentation, which
allows adjusting its position from outside the valve body.
It’s locked by a plug. See the instruction manual for its adjustment procedure.
FEMA CAT01
Rev. 8
Page 16
BONNET AND CAP INTERNAL COMPONENT PARTS
SPRING:
It’s usually made of carbon steel, tungsten steel, or stainless steel and is accommodated in the
bonnet and is secured by two centering spring washers, which are movable on a ball joint and are
guided by a stem.
The mechanical characteristics of the spring are such as to assure a greater elasticity with less
stresses.
The spring’s function is to offer a given resistance to the process fluid’s pressure.
The set pressure is usually calibrated at the ambient temperature; consequently it shall be modified
as a function of the actual temperature as shown in table 74-1 at page 74.
All springs are engineered on the basis of the provisions of the ANCC Standard Collection E, in full
compliance with the applicable safety and low-stress criteria thereof.
ADJUSTMENT SCREW
Its function is to pre-load the spring for calibrating purposes.
The locknut prevents adjusting screw slackening, if any.
BELLOWS
It’s manufactured according to ASTM A 479 Tp 316L or Monel, and its function is twofold:
Balancing:
Provides non-interference between the calibration made and the variable counterpressure.
This function is available for all valves equipped with orifices F - T.
Insulation:
The bellows prevents the GUIDE and all component parts internal to the bonnet from getting in
contact with corrosive fluids and incrustations, both of which are dangerous.
This function is available for all valves equipped with orifice D - T.

SOFT SEAL DISC
All valves can be equipped with a soft seal disc, compatible with the pressure, temperature, and
process fluid conditions.
The use of a seal seat made of a soft material is recommended in the following applications:
whenever the set pressure value is close to the operating pressure value and it is expected
that the valve frequently goes close to the set threshold without reaching it;
when operating in the presence of toxic or corrosive gases with particles suspended
therein;
whenever the valve is installed on pumps, compressors, etc. and is consequently subjected
to vibrations.
