3 Honeywell Proprietary Honeywell.com  3 Document control number Valve Status Indicator Highly visible indication valve position indicator Valve position color contrast is easily visible and distinguishable to the user New visual indicator provides color contrast to identify valve position and flow –Red – indicates no flow, or valve closed position; Green – indicates flow, or valve open position –Red – indicates flow, or valve open position; Green – indicates no flow, or valve closed position –Black – indicates no flow, or valve closed position; Yellow – indicates flow, or valve open position Varying color schemes offer flexibility to meet needs in all production areas

4 Honeywell Proprietary Honeywell.com  4 Document control number Temperature Range Low temperature –Rated for low temperature service to -58ºC (-70ºF) –Low temp cylinders available in NEMA 4 or NEMA 4X type actuators –Low temp solenoids available in all currently available voltages 24VDC, 24VDC IS, 120VAC 50/60 Hz, 240VAC 50/60 Hz High temperature - Fire Safe Rated –Series 8000 is validated to API-6FA (6A/6D) or to API Both standards are based on BS The test involves exposing the valve to flame temperatures of 760º- 980ºC - API-6FA and 607 both require burn period of 30 minutes, which is among the most stringent of the various tests performed API 607 is “Fire Safe for Soft-Seated Quarter Turn Valves” API-6FA is designated “Specification for Fire Test for Valves”

5 Honeywell Proprietary Honeywell.com  5 Document control number Fire Safe Rating Maxon high-quality metal-to-metal sealing preserved in Fire Safe trim options –Fire Safe option available with NACE trim materials –Carbon steel and stainless steel body materials available for use with fire safe trim –Agency approvals maintained with Fire Safe trim (FM, CSA, BSI, AGA, SIL certification) –Available for General Purpose, Div. 2 or Div.1 areas –Body connections meet ASME codes for threaded or flanged valve bodies

6 Honeywell Proprietary Honeywell.com  6 Document control number Shut-off Sealing Mechanism Unique metal-to-metal shut off valve mechanism –Meets FCI 70-2 control valve standard for Class VI seat leakage –Uses a matched set of finely ground shut-off rings mated with a rising stem. –Provides a complete, tight seal that that does not rely on soft seals (that tends to wear out with repeated movement) Cycling the valve provides a self-cleaning, corrective action –Keeps the valve’s performance consistent over longer periods of time –Actually improves seal with repeated use –Valve’s performance is fully enhanced by using Partial Stroke technology –Valve wears in, not out! Metal seat rings are finely honed for a zero tolerance fit with the rising stem Rising stem moves up and down depending on open/close status of the valve Valve shown in open position

7 Honeywell Proprietary Honeywell.com  7 Document control number Seat Leakage Compliance

8 Honeywell Proprietary Honeywell.com  8 Document control number Series 8000 Feature Upgrades New features and enhancements to improve compatibility in the general combustion and O&G markets 8” Size 8000 Safety Shut-off Valve –150# and 300# ANSI as well as DIN flanges in carbon steel, low temperature carbon steel and stainless steel body assemblies –Offered with the same fluid and pressure specifications as the 6” version with internal trim options to handle general purpose or corrosive gases and oxygen compatibility –The 8” valve is fully NACE compliant, and conforms to Fire Safe code API 6FA 3/4” Size 8000 Safety Shut-off Valve –ANSI/ISO threaded, socket welded nipple, socket welded nipple, and socket welded nipple with #150 and 300# flange mountings –Available in carbon steel, low temperature carbon steel, and stainless steel

9 Honeywell Proprietary Honeywell.com  9 Document control number Series 8000 Feature Upgrades External Redundant Solenoids –Dual shut-off solenoids provide additional SIL2 certification levels to offer a higher level of protection against potential solenoid failure. –The redundant solenoid acts in series with the internal solenoid. If either solenoid trips, the valve will close/open (STO). External Redundant Solenoids with Manual Reset –Combination of both external redundant solenoids with manual reset option. –If either solenoid trips, the valve will close/open (STO) and must be reset manually at the site of the valve before operations can resume.

10 Honeywell Proprietary Honeywell.com  10 Document control number Series 8000 Feature Upgrades Material Certifications –Material certification paperwork for full compliance can now be ordered directly through the configurator. NDE (non-destructive engineering tests) –Visual inspection (VI) –Liquid Penetrate (PT) –Positive Material Identifications (PMI) –Magnetic Particle testing (MT) Additional tests that are available with as specials Ultrasonic (UT), Radiography (RT) PED (pressure equipment directive) –Certification for EMEA compliance (Mid 2014)

11 Honeywell Proprietary Honeywell.com  11 Document control number Series 8000 Feature Upgrades Non-Destructive Engineering (NDE) –Certified testing certificates are now available as a stock offering –On bonnet and valve castings as well as valve weld Each is priced per valve For larger lot pricing, call for quote on –Liquid Penetrate (PT), Positive Material Identifications (PMI), Magnetic Particle testing (MT) –By special request - Ultrasonic (UT), Radiography (RT)

13 Honeywell Proprietary Honeywell.com  13 Document control number MAXON PSCHECK Series 8000 Safety Shut-off Valve PSCheck

14 Honeywell Proprietary Honeywell.com  14 Document control number PSCheck and 8000 Valve 8000 Valve when used with PSCheck allows you to run longer between maintenance intervals –Can give insight into probability of failure on demand (PFD) –Can help prevent costly downtime, allows for predictive maintenance –Reduces possibility of undetected valve failures Maxon PSCheck is a patented diagnostic tool which gives insight into valve performance through scheduled partial stroke testing –Data from scheduled testing is collected and trended Detects any valve degradation over time Detects valve failure to open/close –Diagnostic function is completed without system shutdown –Tests run automatically without any user intervention (SIL requirement) –Testing can actually serve as a corrective measure Cleans sealing surfaces, fully leveraging the metal-to-metal seating’s WEAR IN, NOT OUT characteristic

15 Honeywell Proprietary Honeywell.com  15 Document control number PSCheck Features A wide variety of options to customize –1-2 valve, 3-5 valve and 6-9 valve systems Different panel sizes based on number of valves ordered –Order only the number of valves needed Three different panel configuration options: 1.Manual only (1-5 valves) uses push buttons to execute the test manually Test is run manually directly from the panel Shows valve health status via RED (failed test) or Green (passed test) LEDs on the panel Limited feature capabilities 2.HMI only (1-9 valves) uses a touch screen display interface to program custom functions Frequency of test, set failure limits, valve health reporting and trending Set admin lock-out access, full feature access 3.DCS (1-9 valves) no local feedback - direct link to DCS Uses standard communications protocols: Ethernet, Modbus 1761-NET, Modbus AIC+, foundation Fieldbus, HART, and RS 232

16 Honeywell Proprietary Honeywell.com  16 Document control number PSCheck Advantage Common Partial Stroke Testing technologies vary: –Use of a mechanical jammer to limit valve movement during a shut down procedure - confirms that the valve is moving Valve is usually off-line meaning it cannot shut down in an emergency Larger valves are harder to jam to prevent movement No direct feedback on performance No historical trending on valve’s health Must be done at site- valve may be located in a hazardous or hard to reach location –Additional PST hardware mounted directly on the valve Incurs additional cost as every valve requires PST module May require additional external solenoid valves Must keep up on maintenance on each PST module May be located in a hazardous or hard to reach location By having multiple PST modules, it is more difficult to achieve a SIL3 level because of the multiple components and sub-systems

17 Honeywell Proprietary Honeywell.com  17 Document control number PSCheck Advantage Installation and maintenance on the PSCheck System is substantially simplified Use of industry proven Series 8000 pneumatic safety shut off valves –Up to 9 valves per panel (panel sizes vary) –Can mix different valve sizes, MOC, trim options Wiring directly from a panel to the valve No additional hardware, software, or communication links required Lowers installation time, maintenance, total cost for system ownership
