Water Level Gauge Cock Supplier “IWAKO”
When searching for a Water Level Gauge Cock Supplier, the primary requirement is not only product availability, but correct configuration alignment with tank, pressure, and service conditions.
We supply IWAKO Water Level Gauge Cock assemblies complete with tube sight glass for industrial water systems. These assemblies are designed for direct visual level indication with controlled isolation capability.
Applicable systems include:
-
Water storage tanks
-
Boiler water systems
-
Cooling water tanks
-
Utility and process water vessels
The function of a water level gauge cock assembly is to control the connection between the vessel and the glass tube. It allows level verification, safe isolation, and maintenance without disturbing the entire process.
IWAKO Product Configurations
We supply two primary IWAKO configurations depending on system requirements:
1) Stainless Steel Gauge Cock with Tube Sight Glass
Handwheel Type – Stainless Steel Construction
Application Profile
-
Hot water systems
-
Pressurized tanks
-
Process water environments
-
Installations exposed to corrosive conditions
Engineering Characteristics
-
Stainless steel valve body
-
Upper and lower isolation valves
-
Controlled handwheel actuation
-
Glass tube level indication
Operational Logic
The handwheel mechanism allows gradual valve opening.
This reduces hydraulic shock and protects the glass tube from sudden pressure impact.
Stainless steel construction provides higher corrosion resistance and structural stability under pressure and temperature variation.
This configuration is selected where long-term operational reliability is required.
2) Brass Gauge Cock with Tube Sight Glass
Lever Type – Brass Construction
Application Profile
-
Clean water tanks
-
Utility water systems
-
Low to medium pressure service
-
Ambient temperature installations
Engineering Characteristics
-
Brass valve body
-
Quick open / quick close lever
-
Clear visual valve position
-
Complete sight glass assembly
Operational Logic
The lever-type actuation enables immediate level verification.
This configuration is appropriate where routine inspection is required and service conditions are not severe.
It provides practical performance in general water applications.
Optional Configuration for Tube Sight Glass Assemblies
For installations requiring additional mechanical protection, temperature control, or standardized connection compatibility, the IWAKO water level gauge cock assembly can be configured with the following optional components:
Cover Plate
Installed over the glass tube to provide mechanical shielding from external impact.
Used in areas with frequent maintenance activity or potential contact risk.
Jacketing
Applied when the level gauge section requires temperature stabilization or environmental protection.
Suitable for systems where process temperature variation may influence operational stability.
Protection Guards
Structural guards surrounding the glass tube to reduce direct impact exposure.
Recommended for industrial environments with mechanical movement nearby.
Scale
External graduated scale mounted along the glass tube to improve visual level reference.
Useful for defined operating limits or consistent operator verification.
Flange Connection (JIS / ANSI / DIN)
Flanged configurations are available to match site piping standards.
Correct standard selection ensures installation compatibility and reduces on-site modification.
Additional Gauge Cock Valves
Upper and lower isolation valves can be configured according to system requirements.
This ensures safe separation of the sight glass from the vessel during inspection or maintenance.
What to Confirm When Selecting a Water Level Gauge Cock?
For proper specification, the following information is required:
-
Service type (clean water / process water / hot water)
-
Operating pressure
-
Operating temperature
-
Required visible measuring length
-
Connection type (Threaded or Flange – JIS / ANSI / DIN)
-
Installation location (tank side / boiler / utility vessel)
Correct alignment between operating condition and material selection ensures stable performance and maintainability.
As a supplier of IWAKO water level gauge cock assemblies, we provide structured technical confirmation prior to quotation.
Submit your operating data and installation requirements.
We will confirm the appropriate stainless steel or brass configuration and provide a formal proposal based on your system conditions.
