SOLUTIONS FOR
PRESSURE RELIEF / RELIEF
VALVES
The AccuTEST of AccuTEST Systems was designed to test safety valves in-situ and
under full load. With a universal mounting frame, it can be used for all types of
valves. Fully automated, the system provides superior performance in regards to set-
up, operational ease, accuracy of results and reports.
Superior results are achieved through the AccuTEST System, which uses the most
advanced software in the industry. The sophisticated software eliminates the possibility of
human error during any step of operation, from automatic calibration of measurement
sensors to the final result.
Test files are permanently stored on your computer allowing a more complete data
management. You can immediately access and print any information at any time.
Advantage AccuTEST
• Calibration fully automated, test reports. Significantly reduces human error.
• Tests under full load, producing immediate results and benefits.
• Eliminates the need to over-pressurize or reduce pressure, place the plant off-line or remove the valve.
• Saves energy and reduces delays.
• Minimizes erosion in the valve seat.
• Identifies problems quickly and detects incorrect set pressures. Measures line pressure, calculates set pressure.
• High accuracy. Set Pressure Calculation within 0.5%
• Lightweight and portable for easy transport and set-up on site.
• Provides consistent and repeated tests within all ASME codes.

AccuTEST Auto Report
1. Optimization of Maintenance Policies through detection of Valves that have real
need for maintenance
2. Downtime regarding Safety Valves reduced due to previous filtering done on the
field
3. Possibility of extending the period of maintenance of the valve
4. Very high level of accuracy, more than any test bench
5. Calibration of Valve in real working conditions
6. Time of field calibration reduced, approx. 40min per valve
7. Increased reliability on the accuracy of calibration, maximum error 0.5%
8. Inability of calibration loss in the trajectory maintenance shop – plant and
during the assembly in the Line
9. Prevents loss of production and increase the profitability of the Plant

ACCUTEST SYSTEM
SPECIFICATIONS
AccuTEST System Specifications
•System used to test safety valves with exposed stem.
•System has been used in valves of almost all manufacturers
(Consolidated, Crosby, Farris, Foster, Fukui, Lonergan, Kunkleetc.).
•Integral data-base includes thousands of valve types and sizes from various
manufacturers.
•Data-Base can be updated by the user for unusual / special valves.
•User can choose units of measurement in English (lbf, psi, in) or metric (KBF,
kg / cm ** 2, cm).
•It uses a standard laptop and OS Windows 7.
•Pressure and load sensors provide a wide variety of valve sizes and test
conditions.
•The system sensors have an accuracy of + / - 0.1%.
•Typical test accuracy is + / - 0.5%.
•Standard mounting structure allows test forces up to 10,000 lbf(4,500 kgf).
•Customized Mounting Structures available for testing > 10.0000 lbf(4,500 kgf).•Option of Acoustic Detection eliminates operator error and improves accuracy.
•Battery Operated - battery life between charges is
> 24 hours. Uses 120 or 240 VAC to recharge.
•Stem Adaptors are from ¼ to 1 ½ inch (English) and 6 to 36 mm (Metric).
•Force Application is made by an automatic motor remotely controlled by
software or operator.
•Includes test tolerances for safety valves ASME Section I, III and VIII.
•Receives support from ASME Section I, in paragraphs PG. 73.4.2.2.2, Section
VIII, UG. 136 (d) (4) (b), 2013 NBIC code section 3 ( 4.5.2.) and from The
National Board of Boiler and Pressure Vessel Inspectors in paragraph RB -
8400.
•The sensors used in the system are calibrated and certified by
NIST (National Institute of Standards and Technology)
