For service at pressure higher than 1 psig, the valve packing must be readjusted to prevent leakage. Before installation, valve packing exposed to environmental conditions may lose initial packing load, therefore, packing adjustment may be needed. For adjustment instruction, please refer to packing adjustment as follows: Procedure for Packing Adjustments: 1. Relieve the pressure from the system. 2. Remove residue from the valve by operating and closing the valve. 3. Remove the handle after loosening Set Screw. 4. Turn the Packing Bolt clockwise in 1/16-turn (22.5 ) 5. Reassemble the valve in reverse order. 6. Check the valve s operation after adjusting Packing Bolt and repeat this procedure until leak-tight. [ T H E M E A S U R A B L E D I F F E R E N C E ]

Set pressure of each valve after initial relief is repeatable within o ± 3. psig (.2 bar) or ± 5 % (whichever is greater) of the initial set pressure at 6 to 8 F (15 to 26 C) o ± 6. psig (.4 bar) or ± 2 % (whichever is greater) of the initial set pressure below 6 F (15 C) and above 8 F (26 C). Resealing pressure is the upstream pressure at which there is no indication of flow. Resealing pressure is always lower than set pressure.

Then, make adjustment while checking the blowout pressure until the desired level is reached. Tighten the lock nut by the torque of 11.3N-m After final adjustment of the pressure, lock the cap and body with wire DIMENSIONS

Pressure relief valves open when pressurized vessel or system pressure reaches beyond the set pressure and closes when system pressure falls below the set pressure. For valves not actuated for a period of time, initial relief pressure may be higher than the set pressure.
