Guarantee provisions

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.

english

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.

GENERAL DESCRIPTION

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 time­proven, self-adjusting packing gland ensures high seal integrity. The flow
optimizing valve body made of gunmetal (bronze) or stainless steel enables high
flow-rates.
