Frequently Asked Questions
-
Q: What is the primary function of this air cap?
A: It automatically releases trapped air from ship pipelines, preventing air locks and ensuring efficient system operation. -
Q: Can this valve be used for seawater applications?
A: Yes, the bronze version is specifically designed for seawater and other corrosive fluids, offering excellent corrosion resistance. -
Q: What pressure ratings are available?
A: Standard options are PN10 and PN16. Custom pressure ratings can be provided upon request. -
Q: Is the valve suitable for high-temperature fluids?
A: Bronze version can withstand up to 120°C; cast iron version up to 80°C. Always check the medium temperature before selection. -
Q: How is the air release mechanism activated?
