2 INITIAL INSTALLATION

2.1 Unpacking

2.1.1 Valve and Actuator are delivered separately. This

allows for more compact transport boxes and easier

installation. After unpacking the valve and actuator,

clearly mark the parts for proper assembly. The trim is

installed inside the valve body to avoid damage during

transport. To remove the trim assembly from the valve

please refer to section 3.1

2.1.2 Marking (ﬁgure 1)

Valve components have been marked with the serial

number in order to allow a proper disassembly and

assembly. The valve body is marked on top of the

cover plate (1.1), trim kit at the upper part of the

extension(1.2) and the bonnet on the side (1.3). All

relevant technical data is shown on a stainless steel

nameplate attached to the actuator. See also section 5

Identiﬁcation.

2.2 Preparation for vacuum box installation (ﬁgure 2)

2.2.1 After trim has been removed from the valve body (see

chapter 3.1) mount the installation ﬂange (2:1) on the

bonnet ﬂange thread of the valve.

CAUTION: Please ensure that the mounting ﬂange has

been tightened with the correct torque (see table 7.3).

2.2.2 Attach hoisting equipment of adequate lifting capacity

to the hoisting lug (3:1) and lower the valve body into

the vacuum box. See also table 7.2 for approximate

maximum weights of this subassembly.

CAUTION: take care when lowering the valve

subassembly into the vacuum box.

Mounting (ﬁgure 3)

Insert the mounting Tool (3.1) between the valve

cover plate (3.2) and the mounting ﬂange (3.3) before

reaching the ﬁnal position inside the box.

2.3 Welding

2.3.1 Pipe connections

Position the valve inside the vacuum box and secure it

with the mounting tool. The pipe connections for inlet

and outlet can now be welded.

NOTE: Ensure that the trim internals are removed and

that the mounting ﬂange is the correct size.

For the standard pipe sizes refer to table 7.2 BW (mm).

2.3.2 Welding cover plate (ﬁgure 4)

With the mounting tool (4.1) in position tack weld the

cover plate to the vacuum box to secure it‘s position.

Rotating the mounting tool will provide space for the

tack welding.

NOTE: ensure the valve can move freely and is not

under tension while welding it to the vacuum box.

Damage to trim and trim guiding may occur.

Remove the mounting tool (4:1)and weld the entire

circumference of the cover plate to the vacuum tank.

2.4 Pressure testing

After welding all the valves into the vacuum tank

perform a pressure test with all valves. For this all

valves must be ﬁtted with mounting ﬂanges. This

mounting ﬂange has a dual purpose: ﬁrstly it assists

in mounting the valves into the vacuum tank and

secondly to seal the valve at the bonnet connection in

order to pressurize the piping system without the trim

assemblies and actuators mounted.

CAUTION: Ensure all mounting ﬂanges are in place and

properly tightened. A loose mounting ﬂange cannot

sustain the pressure and will result in unwanted or

unsecure leakage.

2.5 Cleaning

With the mounting ﬂanges in place, clean and purge the

entire piping system with a cleaning media to remove

dirt and welding residues from the system.

2.6 Remove mounting ﬂanges (Figure 5)

After completing all tests, cleaning and mounting

procedures, remove all mounting ﬂanges (5.1) and

spacer plates (5.2) from the valves. Flowserve Essen

offers a refund system for returning the mounting

ﬂanges and mounting tools after use. For further details

please contact Flowserve Essen Order administration.
