1. Introduction
Scope of this ManualThis instruction manual provides installation, operation and maintenance information regarding the Schneider Electric VTX70 valve design. This manual focuses only on the valve. If provided with an actuator or any controls, review those manuals for those components.

IntroductionThis eccentric (segmental or partial ball) control valve is designed for high-flow, effective seat sealing and excellent controllability in service. This valve is available in size ranges from DN25 to DN350 (1 to 14 inch) nominal pipe size. There are three rated flow capacity values for each size, full Cv, 40 percent and 60 percent of the full Cv values to best suit the requirements of each application. This valve is available with Raised Face Flange ends or Wafer for Raised Face Flanges.

The valve predominantly used in modulating service and is typically operated by a pneumatic Rolling Spring and Diaphragm actuator or electric operator; however, it can have alternate actuation. Actuation provided by others must be selected and installed to help ensure the valve is not damaged.

These instructions are designed to assist in the installation, operation and maintenance as required for the valve. These instructions should be carefully reviewed by qualified valve users and maintenance personnel prior to use. The valve data sheet should be available or the system diagram to define any hazardous fluids that flow through this equipment. If additional information is required, contact your local Schneider Electric representative or Global Customer Support.

MI 023-163 – December 2020 1. Introduction

Key Parameters♦ Each valve has a data sheet that is intended to be kept in the records of the valve

through the life of the operating plant.

♦ The valve pressure and temperature rating, as defined by either ASME B16.34 (for ASME rated valves) or EN 12516-1 (for PN rated valves) are not to be exceeded.

♦ Soft-seat design option for tight shutoff ANSI/FCI 70-2 Class VI per the pressure curve.

♦ Flow direction: The flow is intended to touch the face of the ball first (as compared to into the steam area of the ball first). Flow direction is marked on the valve body.

♦ Valve Travel (or Stroke): Stated on the Valve Tag.

♦ Single-Acting (Spring Return) pneumatic actuators return the valve plug to the fail-safe position.

♦ If a Double-Acting pneumatic actuator is used, an air lock-up valve is typically provided to help ensure a “fail-in-place” position.

♦ Maximum Ball Rotation: The ball is designed to rotate 90°. This rotation is required to achieve the full valve rated flow capacity.

♦ This valve design is well suited to slurry flow or highly viscous fluids.

♦ Rolling Diaphragm Actuator for better position control.

♦ Single-Acting (Spring Return) actuators will return the valve plug to the fail-safe position.

MI 023-163 – December 2020 2. Installation

To install the valve into the pipeline:

1. Before installing the valve, thoroughly clean pipes internally to remove all debris.

2. Verify that the flange facing for gaskets is clean and in good condition.

3. Use slings to lift the valves. Valves must never be lifted by handwheels or stems.

4. Install the valve in the correct flow direction. Refer to the valve flow arrow cast in the body.

5. Install the valves with the appropriate flange gaskets per the system design. Install and partially torque the body to flange bolting per plant standards.

6. Verify that the valve is centered in the flanges to minimize the stress in the pipeline. Verify that the gaskets do not project into the flow path.

7. Figure 2 and Tables 5 and 6 show the standard bolt sizes and lengths for installing wafer end or flanged end valves.

8. After all bolts are installed, torque the installation bolts to full torque per the pipe system parameters.

9. The weight of the valve should normally be supported solely by the flange bolting.

10. Locate the installation dimensions of the valve body and standard pneumatic actuator in Tables 11 through 14.

NOTEIf the system design always requires that this flow path be available (flowing), a parallel pipeline to bypass this valve should be considered for when this valve must be maintained.

NOTICEPOTENTIAL EQUIPMENT DAMAGE

Exceeding the pressure or temperature limits for the valve can cause damage to the valve, degrading its performance. The valve could become nonfunctional after exceeding the pressure and temperature limits. Avoid exposure above the pressure and temperature limits.

Failure to follow these instructions can result in equipment damage.

Reassembling the Valve AssemblySee Figures 11, 12, and 13 for the exploded views and Tables 15, 16, and 17 for the parts lists.
1. Install the trunnion (item 1) into the valve body (item 5). It is easier to install from the non-seat side.

2. Insert the ball (eccentric segment) (item 2) into the body (item 5), setting it on the trunnion w/bushing (item 1). The key-way or hex side of the ball is installed opposite the trunnion.

NOTEFor the DN350 (14”) valve, the trunnion w/bushing (item 1) may have to be retracted while the ball (eccentric segment) (item 2) is inserted, and then placed back into the ball.

3. For DN25-DN50 (1”-2”): Install the stem guide w/bushing (item 6) on the stem (item 14). Insert it into the ball (eccentric segment) (item 2). For DN80-DN300 (3”-12”): Install the thrust ring (item 15), stem guide w/bushing (item 6), and stem keys (item 16) on the stem (item 14). Insert it into the ball (eccentric segment) (item 2). For DN350 (14”): Install the thrust ring (item 17) and thrust ring w/bushing (item 6) on the stem (item 14). Insert it into and through the ball and into the trunnion w/bushing (item 1). the splines on the stem and ball need to align.

4. Insert the shaft from the prior step into the top of the ball, taking care to align the key, ball, and shaft.

5. Install the packing spacer (item 7), stem packing rings (item 9), and packing follower (item 11).

6. Install the stem packing studs (item 10) if previously removed. Install the packing gland flange (item 12), and packing nuts (item 13). Do not tighten these nuts yet.

7. Rotate the ball (eccentric segment) (item 2) into the opening for the seat ring (items 3 and 4).

8. Torque the packing nuts (item 13) alternating between them, in 1/3 increments to the required torque value listed in Table 8.

9. Install the seat ring (item 3) seat retainer ring (item 4) and for the DN350 (14”), the outer seat seal (item 15), seat energizing springs (item 16), and outer sealing ring (item 18).

10. Tighten the seat retainer to with the seat tool (Figure 6).

11. For the DN350 (14”) valve, install the lower cover gasket (item 20) and lower cover (item 21) with the lower cover bolting (item 19). Torque the bolts per Table 9, alternating between the bolts.

12. Install the yoke and actuator.

13. Calibrate the actuator for proper rotation and travel. If these parts were not changed on disassembly, no action should be necessary. This is done with the adjustable shaft connector (item 10) in Figure 14 and Figure 15. Loosen the hex jam nuts (items 11) to adjust. Tighten the hex jam nuts to lock in place.

14. Calibrate the positioner (if not completed in the above step).

15. Test the system with the valve before putting the system into operation.

Actuator MaintenanceNOTE

The only component of the actuator to maintain is the rolling diaphragm (elastomeric material). Maintenance instructions are limited to replacing this part.

Disassembling the ActuatorSee Figure 14 and Figure 15 for exploded views and Figure 18 and Figure 19 for parts lists.

1. Verify that the actuator is depressurized.

2. Disconnect the air feed from the positioner or other control device to the actuator.

3. Remove the four short hex bolts, washers, and hex nuts (items 16, 17, and 18) and install four bolts that are 200 mm long, if the long bolts are not already provided on the actuator.

4. Remove all the short hex bolts, washers, and nuts (items 16, 17, and 18) from the diaphragm cover (item 1). The long bolts will hold the diaphragm cover in place.

5. Unscrew the four long bolts in roughly equal increments to remove the spring force.

6. Remove the hex nut or hex bolt (item 2) that holds the travel stop (item 3) in place.

7. Remove the travel stop (item 3).

8. Remove the rolling diaphragm and diaphragm plate (item 4 and 5) from the actuator.

9. No further disassembly is required.

Reassembling the ActuatorSee Figure 14 and Figure 15 for exploded views and Figure 18 and Figure 19 for parts lists.

1. Place a new rolling diaphragm (item 4) on the diaphragm plate (item 5). This simplifies installation of the diaphragm.

2. Install the rolling diaphragm (item 4) and diaphragm plate (item 5) into the actuator in the orientation as shown (visible when looking at the assembly, see Figure 14 or Figure 15), aligning the mounting holes with those of the spring cover (item 7).

3. Install the travel top (item 3) and hex nut or bolt (item 2). Tighten to a snug fit.

4. Install the diaphragm cover (item 1) and four equally spaced long bolts.

5. Screw the nuts (item 18) onto the long bolts in roughly equal distances to evenly compress the actuator spring (item 8). Tighten until the diaphragm cover (item 1) and spring cover (item 7) compress around the rolling diaphragm (item 4).

6. Install the remaining hex bolts, washers, and nuts (items 16, 17, 18) and tighten.

7. Remove the 4 long bolts and replace with short hex bolts (item 16).

8. Perform positioner calibration if the actuator is already on the valve. If it is being mounted later, perform the steps for the valve assembly.

WARNINGEQUIPMENT OPERATION HAZARD

These long hex bolts unload the spring force and must be released evenly to help ensure safe removal of the upper casing and springs.

Failure to follow these instructions can result in death or serious injury.
