NORMaL OPERaTION aND MaINTENaNcE

These installation, operating and maintenance instructions

cannot contain all detailed information on all possible

versions for reasons of clarity and, in particular, cannot take

into consideration all imaginable cases for setup, operation

and maintenance. Therefore, only primarily instructions

are contained, which are required for the intended use in

industrial applications. If anything is not clear, particularly if

any detailed information on the specific product is missing,

clarify as required with the responsible FLOWSERVE repre-

sentative.

TROUBLESHOOTINg

When troubleshooting or during general maintenance,

always observe Section 1 “Safety precautions”.

DaNgER:

If a valve contaminated with dangerous sub-

stances has to be removed from the system or pipeline,

decontaminate it properly before performing further mainte-

nance work.

PODUcT DEScRIPTION

9.1 Housing

The body material is made of GGG40.3 (standard), other

body materials are also available from the manufacturer on

request. For valve bodies with plastic liners: See Table 2b

for coating materials.

The liner thickness is at least 5 mm for DN25 and higher

and 3.5 mm for DN15 and DN20.

10 BONNET

The bonnet is connected with a form fit to the valve body

providing, on the one hand, a potential compensation

between the housing and bonnet and on the other a defined

compression force for the body seal and bellows. The bon-

net is provided with a blowout safety system. This means

that the valve stem cannot be pulled or pressed upward out

of the bonnet.

11

PLUg aND SEaT

The seat and plug are screwed, i.e. replacement is possible

at any time when the Kvs value changes or for repair. The

plug is screwed to the bellows and secured against loose-

ning by a PTFE insert. For smaller Kvs values, a Hastelloy

insert can be provided in the plug as well as in the seat (see

Table 3).

The possible material combinations and available Kvs values

and curves are shown in Table 3.

12 BELLOWS

The bellows seal is manufactured from modified PTFE.

TF1620 for DN15, DN20 and DN25 and TFM1600 for sizes

DN40, DN50, DN80 and DN100. The bellows is designed

and tested on a standard basis for an operating pressure of

16 bars at 120 °C. The pressure/temperature limitations are

limited only by the lining material, not the bellows: Observe

the additional operating forces required by the bellows for

sizing your actuator.
