Breather Valves

Caliber breather valves are meant for enclosed bulk storage tanks in the petroleum and other industries. These valves are used as a safety measure to prevent the tanks rupturing or collapsing during filling in and draining out and also to take care of thermal expansion of fluids and consequent pressure build ups. These valves are constructed out of conventional materials and based on the fluids being stored, the valves can be offered in other materials like AISI 304/316, etc. Basically this valve is a combination of pressure relief valve and vacuum breaker put together in a simple and convenient pack. These valves are offered in space saving simple designs, in both flanged and screwed constructions and come in sizes from 50 mm to 150 mm NB. Breather valves can also be furnished with flame arresters and desiccators as per the requirements of the customers.
