Operations and Maintenance - Tank Relief Valves

2550Rsn Floor Type
Hydrostatic Floor Relief Valve

Operation:
The valve opens as a result of hydrostatic pressure outside the wall of a tank exceeding the inside pressure. The opening action allows water to flow into the tank thus equalizing pressure both inside and outside of the tank.

Maintenance:
The valve requires no lubrication. There is no requirement for regular maintenance. Valve seats should be visually inspected for damage when the valve is accessible.

Installation:
Valves are to be mounted vertically only. Care should be taken to prevent damage to the seats when placing in form and pouring concrete. Cover and grate should be installed in the body, turned a quarter turn, and tested to be sure cover and grate can not lift off body.

Parts:
Cover and/or grate are available from Troy Valve, troy, PA.
