These instructions cannot claim to
cover all details of all possible product
variations, nor can they provide information for every

2 Intended Use

Rotary control valves are pressure
vessels designed and rated for specific
application conditions. Before installation, check the serial
number and / or the tag number to ensure that the valve
and actuator being installed are correct for the intended
application. Do not use the valve outside of its rated design
limits. Exceeding the design limits may cause hazardous
conditions including leakage of the process media resulting
in possible process loss, equipment or environmental
damage, or serious personal injury or death.
The specific product design data can be found on the valve's
serial plate, data sheet and the calculation sheet.

Valtek Valdisk High-Performance Butterfly Control Valves
The Valtek Valdisk handles a wide variety of applications, while
offering high flow capacity. It consists of the body, bonnet, trim,
transfer case and actuator.
The product offering may include optional ancillary equipment,

switches or boosters. Digital, I/P, or pneumatic positioners can
be mounted directly, with a mounting bracket or according to
NAMUR standards. Refer to the relevant manufacturer's user
instructions for information regarding other ancillary equipment.

3 Product Identification

Each Valtek Valdisk control valve comes with an attached serial
plate which includes key information specific to the control
valve.

The same serial number shown on the plate will appear on all
Valtek Valdisk data sheets, dimensional drawings, bills of
material, and spare parts lists. Other information located on the
serial plate is self-explanatory for the Valtek Valdisk control
valve.

4 Valtek Valdisk Modification

The Valtek Valdisk control valves are generally delivered as
tested and assembled units, with factory-mounted actuators.
Unauthorized modification of the Valtek Valdisk
control valve voids the product test certification
and product warranties, could drastically affect
product performance, and could be hazardous to
personnel and equipment.
Before Valtek Valdisk re-use, all
necessary tests must be repeated and
recorded in compliance with all test routines, guidelines,
and engineering standards.
