Introduction

In order to fully utilise Garlock valves to their optimum performance it is obligatory to observe this operating
manual. The intention is to support the user during installation, operation and maintenance.
If the following; "Attention", "Danger" and "Note" information is not observed this may result
in poor operation, harm & possible warranty invalidation by Garlock.
Garlock is available for any questions;
addresses see paragraph 9 < Further information >.
Attention
Garlock valves are not subject to Directive 2014/34/EU ("Atex 100 a"), as they have no potential
source of ignition.
For the areas where static discharging is likely, due to non-conductive media, we recommend
the use of the "Antistatic version" SAFETY-SEAL .
Note

Proper use

Garlock valves are exclusively intended, upon installation on or between the flanges of piping system, to lock,
conduct or regulate the flow of media within the permitted pressure and temperature limits.
The planning documents and technical data sheets of Garlock valves describe the permitted pressure and
temperature ranges in relation to the lining material.
These valves must be installed on or between flanges according to EN 1092-1 (DIN 2501) or EN 1759-1, with
sealing strips according to shape C, D or shape E, or flanges according to ANSI B 16.5 Class 150, which are
processed plane-parallel and must be flush. Other flanges may only be installed upon release by Garlock.
When using the gasket, paragraph 2.2 < Safety information for the operator > must be observed.
If a valve is used in continuous operation for regulation, the limits of application according to
the planning documents and technical data sheets of Garlock Armaturen must be observed.
Cavitation must always be avoided.

Safety information

2.1 General safety information
The same safety requirements that apply to the piping system also apply to the valves that are installed in it. The
safety instructions in these operating instructions are those for gaskets that have to be observed in addition.
2.2 Safety instructions for the operator
The following is not the responsibility of Garlock. Therefore the operator must ensure when operating the valve
that
– the valve is only used properly as intended and described in paragraph 1.
– the piping system has been laid professionally and is checked regularly.
– the valve is professionally connected to the piping.
– in the piping system, the common flow speeds in permanent operation are not exceeded. Abnormal
operational conditions such as vibrations, cavitation, erosion (e.g. by wet steam) and a proportion of solid
matter in the medium – especially of the wearing kind – have been discussed with Garlock.
– at operating temperatures that result in hot or cold valve parts (incl. add-ons) and therefore might cause
dangers, the operator provides protective measures against touching.
– manual levers, gearing or drives later installed on the valve are tuned to the valve and is adjusted to the two
final positions of the valve – especially to closing position.
– only expert personnel operate and service the valve.
