+5 Points: FL or EZH
For a Fisher Product : What document provides product diagrams and component part numbers?
Instruction Manual
What are the two rules of thumb you should consider when sizing a regulator?
1. Lightest Spring
2. Smallest Orifice
What type of regulator is the EZR?
+ 10 points if you can name 1 OTHER regulator series of this type
+ 20 points if you can name 2 OTHER regulator series of this type
Unloading style Pilot-Operated regulator
Note: Boot style is only valid if the above is included
+ 10 points : LR125
+ 20 points : ACE95
In a WORKING MONITOR system:
Which regulator takes 65% of the pressure cut (Worker or Monitor)?
Worker
Name one Self-Operated regulator and one Pilot-Operated regulator that could be used with Industrial process fluids.
*Note : Must be standard configuration options!
Self Op: MR95, T205 (also accept 67C, 67D)
Pilot Op: 1098-EGR (also accept MR105, LR125)
How should the T205 be mounted for best performance in Tank Blanketing applications?
A) Spring case pointing up
B) Spring case pointing down
C) With the spring case removed
+ 10 points : Justify your answer.
B) Spring case pointing down
+ 10 points :This orientation removes the added force caused by the weight of the spring, which can make a difference at very low set points.
Must list all 3!
What do the B, M and R stand for in the 627BMR?
B = ______________
M = ______________
R = ______________
B = Balanced Port
M = Enternal Registration (Monitor)
R= Internal Relief
Name at least two ways to achieve Low Gain on a Loading Style Pilot Operated Regulator?
Larger restrictor
Smaller Pilot orifice
Stiffer Spring
Smaller Pilot or Main valve diaphragm
Lower inlet pressure (low pressure differential), Use a Pilot Supply Regulator
Get your paper and Expo marker:
One diagram per group.
Draw a Downstream WIDE OPEN MONITOR SYSTEM
On your schematic, label:
- Setpoints: 10 psig & 15 psig
- Inlet pressure: 100 psig
A/E to verify
(Schematic is on your table for reference)
If there's a tear in the boot-style EZR, what will the downstream pressure do?
+ 10 points : Justify your answer.
Downstream pressure will Rise
+ 10 points : Inlet pressure will leak by the diaphragm/ plug and flow downstream.
Name of the certification standard for sour gas/ corrosive service for metal parts.
+ 5 points : What is the full name?
NACE
+ 5 points : National Association of Corrosion Engineers
What is the main purpose of the Shroud on the plug in the CS800?
To optimize flow
Will also accept:
To create boost
Which Fisher Pilot-Operated regulator is designed for Fixed-Factor billing (meter set) applications?
299H
Note: Other regulators can be used but this one is the most cost effective and best-suited.
A) Relieve Full Capacity
B) Build up the most
C) Start to Discharge
D) Email the Application Engineer
C) Start to Discharge
What is a common diaphragm/ plug material used for steam applications?
+ 10 points : Name the gasket material
Metal, or Metal-to-metal trim
+ 10 points : Graphoil for the gasket
Name three Fisher regulators that offer integral Slam Shut solutions.
Any of the following:
CS800/CSR Series (CS804)
299H (299HV)
EZH (EZH-OSX)
EZR (EZR-OSX)
EZL (EZL-OSX)
627 (627-OSX)
LSR (LS204, LS224, LS254, etc.)
The ___ series is our new regulator that bridges the capacity gap between self-operated and pilot-operated regulators.
+ 5 points : Does this regulator come with an integral Slamshut option?
LSR
+ 5 points : Yes! (LS204/ 224/ 254, etc)
Name the one pilot-operated regulator we offer that has a Spring-to-Open Main Valve.
EZHSO
(Schematic is on your table for reference)
In an Upstream Wide-Open Monitor system:
If the Monitor is installed with to
bleed pressure downstream of the
downstream worker,
the system will have the lockup of the:
A) Worker
B) Relief Valve
C) Monitor
D) Repairs Specialist
C) Monitor
(Schematic is on your table for reference)
In an EZH : if my control line breaks completely, will the regulator fail open or closed?
+ 10 points : Justify your answer
Fail Open
+ 10 points : Pilot will only sense atmospheric pressure.
Pilot will sense atmospheric pressure under the diaphragm, open, load pressure to open the main valve, but can't sense the rise in ds pressure, so it won't close the valve again.
