V5055A-F Industrial Gas Valves

APPLICATION

The V5055 Gas Valves are used with the V4055, V4062, and V9055 Fluid Power Actuators to control gas flow to commercial and industrial burners.

While it is possible to combine any V5055 gas valve with any V4055, V4062, V9055 fluid actuator, a limited range of combinations apply to the applications most often used. See Table 1.

PRODUCT DATA

3. Find the capacity in cf/h. If the capacity is listed in Btu/h, convert to cfh by the following formula:

Capacity in cf/h = :Btu/h (from burner nameplate)

Btu/cu ft (from gas utility)

4. For gases with specific gravities other than 0.64, multiply the burner cfh by the proper conversion factor. See Table

Table 6. Gas Conversion Factors.

Type of Gas sp gr (average) Multiply cf/h by:

Manufactured 0.60 0.968

Mixed 0.70 1.046

Propane 1.53 1.546

Butane 1.98 1.759

5. Use the corrected burner capacity in cf/h when determining the gas valve size in Fig. 1.

6. Determine the maximum pressure drop across the valve and draw a horizontal line at this pressure in Fig. 1.

7. Draw a vertical line in Fig. 1 at the capacity (cf/h) previously determined. Use the corrected capacity for a gas with a specific gravity other than 0.64.

8. Use the valve size at the intersection of the horizontal and vertical lines. If the intersection is between valve sizes, use the next higher size to the right.

GAS VALVE SIZING

1. Check the burner nameplate for (a) the type of gas used, and (b) the gas flow capacity. The capacity will be listed in Btu/h (Btus per hour) or in cf/h (cubic foot per hour).

2. Call the gas utility for information on (a) the specific gravity (sp gr) and (b) Btu per cubic foot (Btu/cu ft) for type of gas used.

TO SIZE TWO IDENTICAL VALVES PIPED IN SERIES

1. Find the cf/h for the type of gas used.

2. Consider both valves as one unit. Determine the total

maximum pressure drop across the unit.

3. Find the pressure drop across the first valve by assuming it to be 45 percent of the total pressure drop.

4. Find the valve size from Fig. 1.

5. The second valve will be the same size as the first valve.

INSTALLATION

IMPORTANT:

The V5055 Valve is designed to provide control of gaseous fuel (natural and LP gas) flow in applications in which there is minimal exposure to water. V5055 Valves used in maritime, beverage, food processing, outdoor and other installations in which occasional exposure to water is experienced may be subject to valve stem and spring corrosion. The presence of corrosion decreases the operating life of the valve. V5055 Valves used in such installations should be inspected at least annually and should have the valve bonnets replaced if corrosion is noted.

A V4055 Valve Actuator with a NEMA 4 rating is also recommended for such installations. The water-tight design of the NEMA 4 rated V4055 Actuator prevents water from entering the V4055 valve stem and spring chamber through the actuator. Under certain conditions, some water may be retained by the external upper portion of the valve body. The retained water is effectively excluded from the valve stem and spring chamber by a functional seal that is incorporated into the NEMA 4 rated actuator.

When Installing This Product…

1. Read these instructions carefully. Failure to follow them could damage the product or cause a hazardous condition.

2. Check the ratings given in the instructions and on the product to make sure the product is suitable for your application.

3. Installer must be a trained, experienced, flame safeguard control technician.

4. After installation is complete, check out product operations as provided in these instructions.

V5055A-F INDUSTRIAL GAS VALVES

WARNING

Electrical Shock Hazard and Explosion Hazard. Can cause serious injury, death or property damage.

1. Turn off gas supply before starting installation.

2. Disconnect power supply for valve actuator before beginning installation to prevent electrical shock and equipment damage.

3. Be sure the valve is installed so the arrow on the valve points in the direction of gas flow. (Gas pressure helps to close the valve.)

Location

Install the valve in the gas supply line downstream from the pressure regulator. The valve and actuator may be mounted in any position that allows sufficient clearance for installation and for repair or replacement.

1. The valve position indicators should be easily visible with the valve and actuator in the final position.

2. The final position of the valve and actuator must allow for damper linkage, if used.

IMPORTANT:

Allow room for turning the valve body (actuator not attached) onto the gas piping. Swing dimensions, measured from the center of the pipe are:

3/4 through 1-1/2 in. valves: 4 in. (101.6 mm). 2 through 3 in. valves: 5 in. (127.0 mm). 4 in. valves: 7 in. (177.8 mm).

Mounting (Figs. 4 through 6)

WARNING

Explosion Hazard. Can cause serious injury, death or property damage.

If flow is not in the direction of the arrow on the valve body, the valve may not shut off.

1. Use new, properly reamed, pipe, free from chips.

2. Do not thread pipe too far (Fig. 4). Valve distortion or

malfunction may result from excess pipe in the valve.

3. Remove the protective caps from the ends of the valve.

Do not attach the valve actuator until the valve body installation is complete.

4. Apply good quality pipe dope resistant to action of LP gas, putting a moderate amount on the male threads only. Use dope sparingly; if pipe dope lodges on the valve seat, it will prevent proper closure.

5. Install valve with the gas flow in the direction indicated by the arrow on the casting.

6. Apply a parallel jaw wrench only to the flat next to the pipe being inserted (Fig. 5). A wrench applied to the valve body itself, or to the end farthest from the pipe being inserted, may distort the casting, causing a malfunction. Do not use the valve for a lever.

7. Be sure the gas flow is in the same direction as the arrow on the bottom of the valve body.

8. Use two threaded companion flanges, two gaskets (included with valve), and 16 bolts (with washers and nuts) for mounting a 4 in.-V5055 Valve. Mount a threaded flange and gasket on each end of the valve as shown in Fig. 6. Then screw the pipes into the threaded flanges. Apply dope sparingly, and use wrenches and vises properly as shown in Fig. 4 and 5.

9. Make sure the power supply is disconnected from the valve actuator. Then mount the actuator on the valve

body and complete the electrical and linkage connections following the instructions packed with the actuator.

OPERATION AND CHECKOUT

Operation

A V5055 Industrial Gas Valve is operated by a V4055, V4062, or V9055 Fluid Power Gas Valve Actuator. The valve opens when the actuator is energized, and closes when power is removed. When closed, the valve seals off against the rated close-off pressure with no power applied. For further information, refer to the Instructions for the actuator.

CAUTION

Equipment Damage Hazard. Operation without proper checkout can damage the equipment.

1. Do not put the system into service until you have satisfactorily completed the following Valve Leak Test, all applicable tests described in the Checkout section of the Instructions for the flame safeguard control, and any other tests required by the burner manufacturer.

2. All tests must be performed by a trained, experienced flame safeguard control technician.

3. Close all manual fuel shutoff valves as soon as trouble occurs.

After the installation is complete, cycle the valve several times with the manual fuel shutoff cock closed. Make sure the valve and actuator function properly. Also perform the Valve Leak Test that follows before putting the valve into service.

Valve Leak Test (Fig. 7)

This is a test for checking the closure tightness of a gas safety shutoff valve. It should be performed by qualified personnel during the initial startup of a burner system, or whenever the valve or valve bonnet is replaced (see Service Information section). It is recommended that this test also be included in the scheduled inspection and maintenance procedures. For a periodic inspection test, follow steps 1, 3, 4, 5, 8, 9, 10, 12, 13, 16, and 17.

6. Open the upstream manual gas cock (A).

7. Run the safety shutoff valve (C) to its fully open position

(through the safety system); then immediately de-energize the system to close the valve.

8. Immerse a 1/4 in. tube vertically 1/2 in. (12.7 mm) into a jar of water.

9. Slowly open the test petcock (F).

10. When the rate of bubbles coming through the water

stabilizes, count the number of bubbles appearing during a ten-second period. Each bubble appearing during a ten-second period represents a flow rate of approximately 0.001 cfh.

To meet U.S. requirements, leakage must not exceed the values listed in Table 5.

office of the appropriate approval agency.

After the test:

11. Close the upstream manual gas cock (A).

12. Close the test petcock (F), remove the test apparatus,

and replace the leak test tap plug (D).

13. Open the upstream manual gas cock (A) and energize the safety shutoff valve (C).

14. Test with soap bubbles to assure that there is no leak at the test tap (D).

15. De-energize the safety shutoff valve (C).

16. Open the downstream manual gas cock (E).

17. Restore the system to normal operation. If two safety

shutoff valves are utilized, each V5055 valve is to be checked for tightness of closure.

SERVICE INFORMATION

WARNING

Explosion and Electrical Shock Hazard. Can cause serious injury, death or property damage.

1. Before servicing, turn off the gas supply and disconnect all electrical power to the valve actuator.

2. Only qualified service technicians should attempt to service or repair flame safeguard controls and burner systems.

3. Do not disassemble the valve bonnet assembly; the valve seat is not replaceable.

4. Failure to properly position and seat the seals in the valve body may result in a hazardous gas leak.

V5055A-F INDUSTRIAL GAS VALVES

Scheduled Inspection and Maintenance

Setup and follow a schedule for periodic inspection and maintenance, including the burner, all other controls, and the valve(s) and actuator(s) for leaking oil. It is recommended that the Valve Leak Test in the Checkout section be included in this schedule. Refer to the Instructions for the primary safety control for more information.

Valve Checkout for Oil Leakage from Actuator

1. Turn off the gas supply at the manual shutoff valve located upstream from the valve(s) being serviced.

2. Shut off all electrical power to the valve actuator(s).

3. Mark and disconnect the wires from the actuator termi-

nals. Remove conduit and disengage the damper linkage assembly (if applicable).

4. Loosen the two set screws from the valve to lift off the actuator.

5. If the actuator is to be replaced and it did not leak hydraulic fluid, skip to Step 11.

NOTE: It is good practice to inspect the inside of the

valve whenever the actuator is replaced. To do so, remove the bonnet assembly, inspect the valve and bonnet. If all is well, proceed to Step 7.

6. If the actuator leaked hydraulic fluid onto the valve (the fluid is red), it must be cleaned off from the valve and bonnet assembly. a. Wipe off the outer valve body. b. Remove the valve bonnet bolts and lift off the bonnet.

10. After positioning the bonnet assembly, replace the screws removed earlier.

NOTE: When replacing the bonnet assembly on the 4”

valve, it must be drawn evenly into the valve body. Finger tighten the 8 screws. Draw the bonnet assembly into the valve by tightening, in order, screws 1, 5, 7, 3 (two turns each). Repeat until the assembly is seated. Tighten the remaining screws.

11. Remount the actuator on the bonnet assembly. Tighten the two set screws (50-60 inch pounds).

12. Replace the damper crank arm assembly.

13. Re-attach the wires removed from the actuator terminals

and turn on the electrical power.

14. With the gas still off, cycle the actuator to check for proper mechanical operation.

CAUTION

Be sure to perform a bonnet seal and seat leak check after installation.

Be sure to read and follow all instructions that come with the actuators, valves, seal and bonnet kits.

Valve Bonnet Replacement

The entire valve bonnet may be replaced without removing the valve body from the gas line. Do not disassemble the valve bonnet assembly; the valve seat is not replaceable.

NOTE: V5055/V5097C and E Valves have additional

internal springs that will push the bonnet up as the bolts are loosened.

c. Inspect the inside of the valve.

IMPORTANT

If fluid is present on the inside surfaces of the valve body or bonnet surfaces, the bonnet assembly or entire valve must be replaced. For part numbers, refer to “Replacement Parts:” on page 4.

d. If the inside surfaces are clear of hydraulic fluid,

clean the bonnet assembly and be sure to remove all hydraulic fluid from the inside and outside of the actuator mounting curb. This is the “cup-like” area around the valve stem. Avoid using a cleaning solution as it may damage the rubber seals used in the valve.

7. If the valve bonnet assembly is in good condition and is not replaced, replace the bonnet seal. Do not reuse the old bonnet seal. See “Replacement Parts:” on page 4 for the seal number.

8. Coat seals with grease provided and position in valve body/bonnet assembly.

9. Carefully seat the bonnet assembly on the valve body. Be sure the seals are in their proper position. On those valves with a spring below the disc, be sure the spring is centered in the indentation on the inside of the valve body.

For part numbers, refer to Replacement Parts in the Specifications section. Complete instructions for replacing the bonnet assembly are included with the replacement part.

Replacement of Seals (Fig. 8 or 9)

When removing the bonnet to inspect and clean the valve, install new seals (see Replacement Parts in Specifications section). Coat the new seals with the grease provided, and position them in the valve body as shown in Fig. 8 or 9.

Failure to properly position and seat the seals in the valve body may result in a hazardous gas leak.

After the new bonnet assembly is installed, or the bonnet is removed for any reason, check for gas leakage around the bonnet seal. Turn on the gas at the manual valve. Paint the seal area with a rich soap and water solution. Bubbles indicate a gas leak. If a leak is detected, check to see that the bonnet screws are tight. If necessary, turn off the gas again and remove the bonnet to be sure the seals are properly seated.
