Up to 3000 PSIG
SG600 Series
Always install Chain
(Ref: IOM #E-207)
The SG800 series valves are designed with chain lever actuation, which permits one pair of chains to operate both valves simultaneously. To calculate the length of chain required for these valves, use the elevation required times two, to result in the length required for one set of valves.
The SG600 and 700 series valves are designed with chain wheel actuation. This requires a loop of chain for each valve. Also, the upper valve wheel extends further away from the valve body than the lower valve to prevent interference between the two chains. When calculating the amount of chain required for these types of valves, use the elevation of drop required times 4 to result the total length required for one set of valves. Chains on wheel operated valves must NOT be linked together. If installed such as a bicycle chain, the result is that one valve is likely to close and one valve will not close. Sg600 and SG700 valves must operate independently.

3. Specifying Ball Checks on Water Gage Valves
Ball Check Valves (Reference: “Automatic Shutoff
Valves” in the Appendix of the ASME Boiler Code)
A-18 in the Appendix of Section 1 defines the
design requirements for this User OPTION.
Ball Checks are not mandatory.
Consider the application, before specifying
Water Gage Valves with the Ball Check
feature. We suggest them for limited
applications.
The orientation of a water gage glass is critical for end user satisfaction. On projects with multiple drums, consider orientations that are logical with respect to stairwells and obstacles, which could improve level reading and reduce the amount of time required at the drum, which is typically a high temperature environment for personnel.
When hazardous atmosphere applications occur, verify the elevation of the drum with respect to the area classification. Often times, the area classification can be relaxed from to hazardous to weatherproof, if the drum is greater than 35 feet above grade, but only the user can make that decision.

4. Types of Direct Reading Gages
Simpliport
(Bi-Color)
Prismatic
(Reflex)
Tubular Glass
Flat Glass
(Transparent)
There are four types of direct reading water gage glasses, as follows:
Tubular, Prismatic (also known as Reflex), Flat Glass (Transparent) and Bicolor (Ported) type.
We do not suggest tubular glass for permanent installations. Tubular glass offers the least protection for plant personnel, and should only be used for boil-out or chemical cleaning purposes.
Prismatic water gages often do not require any illumination accessories. These gages are easily viewed in areas with sufficient ambient lighting.
Flat Glass water gages should be installed with illumination accessories, in order to adequately read the level. These gages are designed with mica shields
which reduce an observers ability to read the level, when installed without back-lighting. Our illuminators are designed to illuminate the gage from behind the gage in an uphill manner, which illuminates the depth of the meniscus (water line), and enhances the line to a star-like brightness.
Bicolor water gages are the only option for applications in excess of 2000 PSI,, but can be used at any pressure, especially with the recent development of the Simpliport 180, which makes this option attractive for many low pressure applications, especially for the operations personnel.
Our Simpliport is a unique design, featuring a single retaining nut for each glass module, which reduces maintenance time , when compared to other manufactures with multiple fasteners. Also, our gages are constructed with welded body sections, which facilitates gage repairs, if neglect results in a steam cut surface, whereas, other manufactures would have to be discarded.

5. Water Gage Glass Guidelines
Verify compliance with ASME Section I requirements
Confirm serviceable condition of gage glass
Consider viewing orientation of the gage for operator convenience
Consider gage design alternatives based on:
Viewing distance required
Atmosphere (indoor/outdoor/hazardous)
Design pressure
Water quality
Illumination requirements
Potential for mirrors to save stair climbing

6. Simpliport Bi-Color Water Gage Glasses
Operate on the principle of light refraction
Light refracts through water different than steam
Displays “Green” to indicate the presence of water
and “Red” for steam.
Gage must be outfitted with an illuminator in order to be Code Compliant
The bicolor principle will operate properly, if the water gage is kept clean, the lights are in working order, an the boiler water is clear. Most users have excellent water treatment these days. However, if the user has brownish colored boiler water, the light refraction within a ported gage will not display
optically correct. This is rare, but consider flat glass instead if a customer reports to have very poor water quality.
If a user reports a red crescent in the water (green) area of the gage, it is due to contamination of the mica shields, and the water gage should be blown down. If the situation continues, then the gage should be rebuilt.

7. Simpliport Bi-Color Gages
Steam shows RED Water shows GREEN.
The red and green colors are strategically located in the illuminator for proper color orientation..

11. Advantages of Simpliport Design
Single Nut design to retain glass = less fasteners than others = less maintenance time
Welded body design permits repairs to individual body sections for a fraction of the cost of a replacement gage.
Lighter weight design compared to others.
Replacement parts remain available for previous models, and now include
the heavier mica shields for longer life
The single nut glass retaining design is unique from Clark-Reliance. Other manufactures gages may require complete replacement, if a seat area in a port is damaged. Our design facilitates repairs.

The Simpliport 180 system reduces maintenance time and power consumption. We suggest that you consult us with the actual dimensions and centers on original gages that were originally supplied with traditional incandescent or halogen lighting prior to retrofitting the Simpliport 180. Fit up may be a concern for older gages that were designed on minimum centers.

15. Simpliport Water Gage Maintenance Video and Instructions
See our Maintenance Video at
Ref: Instruction manual #R500.E241-A for P4000/P4100
Series Gages (mfr: 2008 to present) using PW-87B modules
For older model Simpliport Gages P3000/P3100 (mfr. from
1962 thru 2007) using PW-24BR modules, see video at
and instruction manual 539I
General Comments for all models:
Examine gasket surface, before installing new glass modules
Use Glass Bead process to clean packing nut threads
Always clean, inspect, and lubricate spring washers & threads in packing nuts, prior to assembly.
Use care when handling Simpliport replacement modules. Be certain the gasket seating surface in the gage body is completely clean prior to installing new parts.
Also, it is a good practice to check the fit of the cleaned packing nut threads onto the gage body, prior to installing the replacement glass components. This will ensure there is no restriction from residual dirt or corrosion on either of the threads.

16. Simpliport Water Gages
Suggest a Maintenance log for users to record ports that have been serviced. Replace remaining ports, after 30% have been replaced.
Red crescent shape in green area below level (meniscus line) generally indicate internal contamination.
Illuminator and Hood misalignment may affect image on older models without LED Illumination.
Users with many gages in their plant realize accurate tracking, by data logging all the repairs by exact location. This data helps the user decide when to rebuild a gage or if there is a suspect port, if repeat leakage occurs in the same particular port.
