PRESSURE VACUUM VENT VALVE (CCOE Approved)
In a notification dated 18.03.2008, of amendment to the Environment Protection Rules, 1986, Ministry of Environment & Forests – Govt. Of India - has made installation of a pressure vacuum vent valves on tanks of above 4 KL capacity storing products with total vapor pressure of more than 10 KPA mandatory. This, in effect, covers even the smallest M.S. underground tanks in retail outlets. Currently these tanks are provided with open vents protected by wiremesh screens.
TRISTAR PV Vent Valve has been designed to meet this need. Light & compact in design, it has two co-axial valves to relieve excess pressure and vacuum from these tanks. Generous vapor paths give more than adequate venting capacities. Twin ports are protected by two layers of stainless steel size 11 wire mesh & suitable weatherhood. Mounting on the vent pipe is by simply screwing on the pipe threads. The relief points are factory set for accuracy. Materials of construction of components have been carefully selected to ensure long & trouble free service.
Oil industry estimates that installation of PV Vent on u/g tanks can result in annual saving of a minimum of 0.1% of the throughput. This translates into substantial savings for even a small retail outlet. Most attractive part is that the valve pays for itself in a matter of months.
