The ZCGLY-II Gauging Hatch is a foundational safety and measurement accessory for atmospheric and low-pressure storage tanks. Unlike traditional flip-top models, the ZCGLY-II utilizes a precision-engineered horizontal rotating gauge hatch cover. This design is specifically optimized for tank tops with limited vertical clearance, allowing operators to easily swing the lid open for manual gauging, temperature sensing, and sampling tasks.
Producdt Description:
The ZCGLY-II Gauging Hatch (also commonly referred to as an oil measuring hole) is a critical safety and measurement accessory engineered for atmospheric and low-pressure storage tanks. Unlike standard vertical-opening hatches, the ZCGLY-II features a sophisticated horizontal rotating gauge hatch cover. This specialized design is the industry standard for tank tops where vertical space is restricted, providing a smooth, swing-away action that facilitates rapid access for manual gauging, temperature sensing, and product sampling.

Q1: What is the primary advantage of a rotating cover over a hinged cover?
A1: The rotating design of the ZCGLY-II gauge hatch cover is ideal for installations with limited vertical space and is less affected by wind during operation, providing a more stable access point.
Q2: Does the ZCGLY-II Gauging Hatch prevent vapor leakage?
A2: Yes. It features a precision-machined sealing face and high-quality gaskets that create an airtight barrier, effectively containing tank vapors and preventing VOC emissions.
Q3: Can this hatch be used for highly corrosive chemicals?
A3: Absolutely. While Carbon Steel is standard, we provide Stainless Steel (SS304/SS316) options specifically designed to withstand aggressive chemical environments.
Q4: Is the operation of the ZCGLY-II spark-proof?
A4: Our designs include options for non-sparking materials and linings to ensure safe manual operations in hazardous, explosive zones.
Q5: What sizes are standard for this model?
A5: We typically supply DN100 (4″) and DN150 (6″) sizes, but we can manufacture custom diameters to match your specific gauge hatch tank requirements.
