Eva Wong –
How does the valve handle low water pressure?
Imran Hanafiah –
Thank you for your question, Eva. Our Mares Single Connection Tank Valve (Catalina Cylinders) is designed to function effectively with a wide range of water pressure levels. However, if the water pressure drops to an extremely low level, it may affect the valve’s performance. Generally, the valve works within a pressure range of 100-300 kPa. At pressures below 100 kPa, the valve may not open or close fully. But this is still within a safe range for most recreational diving applications. For any further questions or clarification, please don’t hesitate to ask.
