Why Live Load Valves? Warm Cycling Vibration Packing Set Adjustments Critical Dynamic Applications

Slide 11

Chesterton Valve Live Loading System

Slide 12

5800 More Efficient Axial to Radial Stress Transfer 30% Lower Stem Friction than Standard Die-shaped Rings Specifically Designed For and Tested in Control Valves Parameters 800°F for oxidizing 1200  F Max. Temperature (steam) 5000°F Max in non oxidizing 3000 psi Max. Weight For all administrations aside from solid oxidizers

Slide 13

5800T WedgeSeal™ Parameters 600  F Max. Temperature (steam) 2500 psi Max. Weight For all administrations aside from solid oxidizers Features High Thermal Stability Better than Fluoro-elastomer V-Rings Consistent Sealability through warm cycles Provides bring down grating roughly 20-30% beneath 5800E

Valve Packing Installation Review

Slide 15

If conceivable, secondary lounge the valve to utmost passage of outside material into valve and to help in valve stem assessment. Evacuate and clean the pressing organ nuts Raise pressing organ and, if fundamental, tie organ clear of the stuffing box. Tidy any synthetic develop or stores on organ and stem. Utilize mind not to score the stem or stuffing box amid pressing expulsion. Expel old pressing from valve utilizing a pressing extractor or, if stuffed with GTPI, a mechanic recorder. Safeguard all pressing is evacuated. Clean stem and stuffing box of all buildup.

Slide 16

The valve stem and stuffing box divider ought to be smooth and free of any arrangement of pits, cuts, scratches or scratches in a line that could go about as a way of spillage paying little heed to their profundity. On the off chance that the stem or stuffing box is too much set tell the correct staff. Stem unpleasantness or potentially high spots will decimate the pressing. Scale can allow spillage through itself and subsequently around the pressing. Stem measurement resistances ±.003. Stuffing box width resistances - .003 +.015 Stuffing box complete 32-125 RMS. Typicality, squareness, and parallelism inside .005, not more than .015 on any single surface. The valve stem and stuffing box ought to be free of exorbitant wear, scale and erosion. Don't repack if this criteria is not met.

Slide 17

On an open segment of the valve stem, confirm the stem complete is 10-32 RMS. This test is to assess the general machined surface of the stem, it is not an assessment of irregular minor setting. A basic strategy to make this assessment is by dragging a fingernail first over a standard complete square and after that over the lay or edges of the stem wrap up. On the off chance that the stem does not meet this criteria, don't repack the valve with unadulterated graphite style packings. With legitimate endorsement the stem might be expelled from the valve and cleaned to meet this criteria. On the off chance that the stem can't be modified to meet this criteria, repack the valve with Chesterton 1601 or affirmed identical.

Slide 20

Installation of Rings Insure that the stuffing box is perfect and free of flotsam and jetsam. Wear defensive gloves to safeguard there is no sullying of pressing rings. Softly coat set valve stems (Manual valves) with Chesterton 772 Premium Nickel Anti-Seize Compound. Introduce carbon sleeves if fundamental after necessities Install a One-CI slice ring to the base of the stuffing box. Situate the ring by utilizing a Chesterton Valve Tamping Tool. Introduce redress amount of 5300/5800 pass on shaped rings. Rings are normally provided with a solitary skive cut whose joints should be stunned 180° separated. In the event that rings are provided with a twofold cut (two parts) or for the 5800 stun joints 90° separated. Twofold cut rings are here and there required due to valve plan or solidness of rings. Care ought to be taken not to blend parts. Rings that are single cut should precisely be curved open and introduced around stem as opposed to spreading them separated. Tenderly preseat every ring utilizing a Chesterton Valve Tamping Tool. Introduce a One-CI cut ring on top. Make sure to seat ring legitimately. The last One-CI cut ring ought to be flush or underneath the highest point of the stuffing box, never above.
