Q1: Why is a locking mechanism important for an oil measuring hole? A1: A locking gauge hatch prevents unauthorized personnel from opening the tank, which is essential for preventing product theft, unauthorized sampling, or accidental contamination.
Q2: Does the locking feature affect the airtight seal of the hatch?
A2: Not at all. The locking mechanism is designed to work in tandem with the pressure-tight gauge hatch cover, ensuring the tank remains fully sealed when locked.
Q3: Is the ZCGLY-II suitable for use on chemical tanks?
A3: Yes, we offer the ZCGLY-II in Stainless Steel (SS304/SS316) models with chemical-resistant gaskets to handle aggressive media.
Q4: Can this hatch be used for manual dipping and level sensing?
A4: Absolutely. Once the lock is removed, the rotating cover provides a clear, unobstructed path for manual dipping tapes and sampling containers.
Q5: What flange standards do you support for installation?
A5: Our gauge hatches are manufactured to meet global standards including ANSI, DIN, JIS, and GB, ensuring seamless integration with your existing tank flanges.
