See Figure 2 for an example of a devloe to relieve body pressure in case the valve accidentally pope. The maximum acceptable leakage rates are defined for pressure relief valves with set pressures from kPa gauge 15 psig to 41, kPa gauge psig.
If greater seat tightness is required, the purchaser shall specify it in the purchase order. The test medium for determining the seat tightness—air, steam, or water—shall be the same as that used for determining the set pressure of the valve.
For dual-service valves, the test medium—air, steam, or water—shall be the same as the primary relieving medium.
To ensure safety, the procedures outlined in this standard shall be performed by persons experienced in the use and functions of pressure relief valves. Other Browser: Other 0. Direct Navigation IP: Not Logged In Member?: NO Cart:
