Producdt Description:
The standout feature of the ZCGLY-II is its sophisticated horizontal rotary opening mechanism, which distinguishes it from standard vertical-lifting models. By allowing the gauge hatch cover to swing parallel to the tank flange, this gauge hatch eliminates the need for vertical clearance. This makes it the ideal gauge hatch solution for crowded tank tops, offshore platforms, or industrial installations with restrictive overhead piping where a traditional hinged lid would be obstructed.

Maintenance and Selection Guide for Rotating Gauge Hatches
Q1: What are the main benefits of the “Rotary Type” design?
A1: The rotary type design allows the gauge hatch cover to swing horizontally, which saves space on the tank top and prevents the lid from being caught by high winds during operation.
Q2: Is the ZCGLY-II suitable for highly volatile liquids?
A2: Yes. Its precision seal is designed to contain vapors effectively, making it ideal for storage tanks containing crude oil, gasoline, and other volatile chemicals.
Q3: Can I perform manual dipping and sampling through this hatch?
A3: Absolutely. Once rotated open, the hatch provides a clear and unobstructed path for dipping tapes, thermometers, and sampling containers.
Q4: What materials can I choose for my ZCGLY-II hatch?
A4: We offer Carbon Steel for standard oil applications and Stainless Steel (SS304 or SS316) for corrosive or hygienic chemical storage.
Q5: How do I ensure the hatch remains airtight over time?
A5: Regular inspection of the sealing gasket and ensuring the locking bolt is properly tightened after each use will maintain its vapor-tight performance.
