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 ]

RELIEF VALVES TECHNICAL DATA: Set Pressure Rating To obtain good pressure settings over the entire pressure range, the entire pressure range is sub divided into 8 pressure ratings. A pressure rating corresponds to a certain spring, which can be used for setting a maximum pressure, is referred below.

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. Testing Cleaning and Packaging Every valve is factory tested for functionality at the relevant cracking and resealing performance. Every valve is cleaned and packaged in accordance with Truelok standard specifications of cleaning and packaging procedures, P14 & P17.

Break and remove the pressure tag wire Unscrew the lock nut and remove the cap from the bonnet Remove the included spring and spring support Check that all parts are celan Insert the spring support from the top of the bonnet Mount proper spring for the desired pressure range Remove the label from the cap and affix a new one, Make sure the desired pressure falls within the range shown on the table Screw in the cap to the bonnet by the Number of times to turn the cap. Then tighten the lock nut and test the set pressure. To adjust the set pressure, remove the pressure from the system and loosen the lock nut. 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.
