Valtek GS
General Service Control Valve - Valtek GS
The Valtek GS product line is low cost, compact and light-weight. Yet, it is rug-
ged and can be used safely and confidently in a wide range of general service
applications plant-wide. Its modular design provides trim and material options to
suit most service situations. Simplicity of design reduces maintenance and parts
inventory costs. It is ideally suited for flow and pressure control of liquid and gas
media in oil and gas, power, chemical and petrochemical processing and related in-
dustries. The Valtek GS control valve package provides flow rates, control accuracy
and reliability at levels comparable to special engineered service control valves, but
at a significantly lower cost. The Valtek GS is manufactured to ISO 9001 standards.
The following instructions are designed to assist in unpacking, installing and per-
forming maintenance as required on Flowserve Valtek GS control valves. This in-
struction manual does not include specific product design data. Such data can be
found on the valve's serial plate or specification documents; additionally, dimen-
sional information can be found in the Valtek GS technical bulletin. Procure needed
documents as necessary before you begin any work on the valve.
User Instructions cannot deal with all possible situations and installation options.
It is required that only trained and qualified technicians are authorized to adjust,
repair or work on control valves, actuators, positioners and other accessories.
Review this bulletin prior to installing, operating or performing any maintenance on
the valve. Additional Installation, Operation, and Maintenance Instructions (IOMs)
cover other features (such as special trim, actuators, handwheels, packing and
positioners).
To avoid possible injury to personnel or damage to valve parts, WARNING and
NOTICE indicators must be strictly followed. Modifying this product, substituting
non-factory parts or using maintenance procedures other than outlined could
drastically affect performance and be hazardous to personnel and equipment and
may void existing warranties. This manual should be used in conjunction with
applicable local and national laws. Failure to comply with User Instructions will
render the manufacturer's guarantee and liability null and void. Unless otherwise
agreed, the manufacturer's general terms and conditions of sale shall apply.
Read the user instructions carefully before use.
