• Always disconnect from power before working on the system!
• Please note that systems must first be depressurized before lines and
valves are disconnected!
• Take necessary precautions to prevent unintentional activation or
unauthorized interventions!
• If electrical power supply or pneumatic pressure sources have been
interrupted, make sure that system processes are restarted according to
defined specifications. Monitor the restart of system processes!
• We refuse all liability resulting from a failure to adhere to these instructions as
well as unauthorized operations on the device. Such actions likewise
invalidate the warranty on the devices and accessories.

Guaranteeprovisions
This document contains no warranty statements. Please refer to our general
terms of sales and business. The prerequisite for the guarantee is the use of the
device in accordance with the prescribed operating conditions.
After delivery of goods, please immediately check the contents for damage and
compare the goods actually delivered with those items specified in the delivery
note. Please contact our Customer Service department regarding any
discovered inconsistencies:

CAUTION!
The guarantee only warrants that the valve, Type 2000/2002, is
free of defects. No liability is accepted for loss or damage of
any type resulting from failure or malfunction of the device.
The externally piloted angle-seat valve (Type 2000/2002) / globe valve (Type
2002) consists of a pneumatically operated piston actuator and a 2/2-way
valve body (angle-seat valve Type 2000/2002) / 3/2-way valve body (globe
valve Type 2002). The actuator casing is manufactured of polyamide (PA) or,
alternatively, polyphenylene sulfide (PPS) for special applications. The time-
proven, self-adjusting packing gland ensures high seal integrity. The flow
optimizing valve body made of gunmetal (bronze) or stainless steel enables high
flow-rates.

NOTE
Accidental switching of the pressure inlet lines for the service
port lines during connection of globe valve Type 2002 can
actuate valve operations other than those intended for the
selected control function.
Valves directing the flow over the seat should not be used for
liquid media; there is a danger of waterhammer!
