General Information
Liquid Controls valves are designed for a wide range of applications and flow rates and have minimum head loss. Careful engineering and construction ensure smooth, accurate, and controlled operation.
The V-Series mechanically actuated piston valves are available in 3” and 4” sizes, and are designed for mounting on the meter outlet to provide tight shut-off with
smooth and easy operation regardless of system line pressure. The valves may be manually operated or connected via a mechanical linkage to a preset counter on the meter for singe-stage closure (for low flow applications) or two-stage closure with dwell period to eliminate hydraulic shock. The valves are indexible in 90º increments for up, down, or side facing outlet.

V-15 & V-30 Valves
General
V-15 valves are designed for use on M-15 and M-25 positive displacement flowmeters; V-30 valves are for use on M-30, M-40, and M-60 positive displacement flowmeters.
V-15 & V-30 valve operation is smooth and easy regardless of the line pressure since the vector forces are directed at right angles to the valve opening mechanism and are never in opposition to it.
Depending on the preset, the valve may be operated as |
Figure 1: V-15 & V-30 Valves |
|
|
either a two-stage valve with dwell period shut-off or as |
|
a single-stage valve with abrupt shut-off. Single stage |
|
valves are recommended when the application flow rates |
|
are low. |
|
How V-15 & V-30 Valves Work |
|
|
Inside the valve housing, a cylindrical bore connects the |
|
|
valve inlet and outlet. Contained within the bore is a |
|
|
piston assembly. Measured liquid exiting the meter outlet |
|
|
is blocked from entering the valve inlet by the piston and |
|
|
seal. |
|
|
As the meter operator shifts the handle to the open |
|
|
position, a mechanical linkage connecting the valve to |
|
|
the preset counter trip ring causes a latch to engage and |
|
|
hold the valve open allowing liquid to flow. |
|
|
In the open position, the valve handle assembly |
|
|
compresses the piston spring and pulls the piston shaft |
|
|
and the piston away from the valve outlet. As the piston |
|
|
is pulled away, it disconnects from the inlet seal, allowing |
|
|
liquid to flow. |
|
|
In most metering applications, closing the valve is a two- |
|
|
stage process. At a predetermined dwell period, the |
|
|
preset counter, while counting down to “0”, releases a |
|
|
latch mechanism, allowing the valve to close to |
|
|
approximately 10% of full flow. This initial closing causes |
|
|
the piston inside the valve to slide toward the outlet, |
|
|
restricting product flow. |
|
|
As liquid is blocked by the piston, some product passes |
|
|
through the valve. The dwell period prevents hydraulic |
|
|
shock while permitting the preset counter to register the |
|
|
remaining flow. |
|
|
As the preset counter reaches “0”, the preset counter |
|
|
trip ring disengages from the dwell position to the fully |
|
|
closed position. This action releases the valve handle |
|
|
and relaxes the piston spring, permitting the piston to |
|
|
contact the outlet ring seal and complete its closure, |

|
stopping product flow. |

Accessories
Flanges
Flanges are offered in 3 and 4 inch BSPT and NPT sizes and weld types. Material of construction is aluminum. Teflon, Viton, and Buna seals and gaskets are available.
Linkage and Valve Handles
Valve handle and linkage assemblies (Figure 3) are accessories used when normal manual ON and OFF valve operation is desired. Different handle and linkage configurations can be ordered separately for field
installations. Figure 3: Linkage Assemblies
There are two valve handle options. When using a mechanical preset, the 40984 curved handle (provided as part of the linkage assembly) is used with both the V- 15 and V-30 valves. For applications without a preset, the A3750 faucet valve handle kit is used.
Unlike the V-7 Valves, the V-15 and V-30 linkage assemblies come complete with the 40984 handle. The available Linkage Assemblies for V-15 and V-30 valves are listed in the table below.

Installation
New Installations
When ordered with a new metering system, the V-15 or |
V-15 Valve |
V-30 Series Valve is supplied mounted to the outlet side |
|
of the meter as shown in Figure 4. A liquid line must be |
|
connected to the flange on the outlet side of the valve or |
|
to the accompanying check valve. The flange connection |
|
on the V-15 valve is 3” BSPT or NPT. The flange |
|
connection on the V-30 valve is 4” BSPT or NPT. Weld- |
|
type flanges are available as an option. |

Retrofit Installations
! WARNING
Relieve Internal Pressure
All internal pressure must be relieved to zero pressure before disassembly or inspection of the meter or any of the meter accessories.
Serious injury or death from fire or explosion could result from maintenance of an improperly depressurized and evacuated system.
Depending on the existing configuration, adding a V-15 or V-30 Valve may require modification of the outlet piping.
After the internal pressure is relieved from the system, drain all the fluid from the flowmeter and accessories. The outlet line can then be disconnected from the flowmeter.
Installing the Valve
The V-15 or V-30 valve is installed on the outlet side of the flowmeter. The valve may be installed in one of four orientations as shown in Figure 5. Determine the orientation desired and then attach the flowmeter using the four bolts and washers provided. Tighten the bolts in a crossing pattern.
Installing the Linkage Assembly
The handle and linkage assembly is provided with the V- 15 and V-30 Valves. The handle and linkage may need to be repositioned depending on the valve orientation. Refer to Figure 5 to determine the handle and linkage positions based on the valve orientation.
The valve handle mounts on either side of the valve shaft. Mount the valve handle to the valve shaft and tighten. With the handle securely mounted to the valve shaft, the linkage assembly can be connected to the preset ring located under the mechanical register.
The linkage assembly connects to the preset ring via the ball joint extension (Figure 6a). The ball joint extension is mounted using the screw and nut provided.

Retrofit Installations (continued)
Mount the ball joint extension to the preset ring by threading the screw into one of the holes at the back of the register assembly. Thread the nut in place on the screw.
With the ball joint extension secure on the preset ring, attach the linkage assembly (Figure 6b). The linkage assembly may require adjustment in order to mount to the ball joint extension. If this is the case, either loosen the handle and reposition on the valve shaft, or loosen the nuts at the handle pivot (Figure 6c).
Once the handle and linkage assembly is secure, proceed with setting the dwell and zero shut-off as described on Pages 9-10.

Disassembling the Valve
The V-15 & V-30 Valves are under pressure from the compression spring. The safest method for opening the valve for service or maintenance is to place the valve on a flat surface with the valve outlet facing down.
1.Loosen the four bolts (Items 610 & 611) located on the valve cap (Item 124). The compression spring will exert a force on the cap and push it up.
2.When the four bolts are almost completely removed, check to see if the compression spring is still exerting a force on the cap. If not, remove the four bolts and washers completely. If there is still force on the cap, remove two screws from opposite sides of the cap. While bracing the cap with one hand, remove the other two bolts and carefully release the cap until the compression spring exerts no force.
3.Note the orientation of the cap and valve handle. Remove the cap (Item 124). The internal components are attached to the cap and will come out of the valve housing with the cap.
4.To disassemble the cap assembly, it will be necessary to remove the four cotter pins which hold the cup (Item 133) to the links on each side of the cup. This is only necessary when replacing the compression spring or the cup.
5.To replace the dashpot washer, remove the retaining ring on the end of the guide shaft.

Disassembling the Valve (continued)
6. Reposition the valve assembly so that the outlet side is facing up.
7. Remove the two screws (Item 615) that hold the guide (Item 138) and seal in place and remove the guide and seal.
The valve shaft (Item 368) is not removable, but it is not necessary to remove it in order to inspect or replace the O-Rings and bearings of the valve shaft.
8. Remove the retaining ring (Item 564) from one side of the valve shaft.
Figure 9: V-15 Valve Guide
9.Remove the shaft seal (Item 270), the bearing (Item
140)the O-Ring (Item 455), the inner bearing (Item
260)and the O-Ring (Item 450).
10. Inspect and replace these components as needed.
11. Repeat steps 8-10 for the other side of the valve shaft.
Figure 10: V-15 Valve Cap
Reassembling the Valve
For reassembly, refer to Figures 7 & 10 or the parts breakdown on Pages 17 & 19.
1.Place the seal (Item 354) into the valve housing.
2.Place the guide (Item 138) into the valve outlet.
3.Secure the seal and guide using the two screws (Items 615). Tighten the screws.
4.Turn the valve so that the outlet faces down.
5.Reassemble the valve by placing the dashpot washer and retaining ring on the end of the guide shaft.
6.Place the complete cap assembly on the valve housing remembering to orient the valve handle in the same position as it was prior to disassembling.
7.Insert the four screws and washers into the valve
cap and tighten by alternately tightening each screw a few turns so that the cup (Item 133) slides evenly over the guide (Item 138).
8.When the cap rests against the valve housing evenly, tighten all four screws in a crossing pattern.
9.If the valve shaft components were removed for inspection or replacement, reassemble the valve shaft components following the drawing above.
10.Insert the O-Ring (Item 450), the Inner bearing (Item 260), the next O-Ring (Item 455), the next bearing (Item 140), the shaft case seal (Item 270) and secure with the retaining ring (Item 564).
This completes reassembly. The valve may be placed back in service. Refer to Pages 6 & 7 for installation instructions.
