General Information; Unpacking; Installation - Flowserve Valtek VL-C User Instructions

General Information

The following instructions are designed to assist in installing, trouble-
shooting and servicing Valtek VL-C spring cylinder linear actuators sizes
100, 150 and 200. Separate installation, operation and maintenance
instructions cover 25 and 50 sizes as well as additional features (such
as handwheels, limit stops, fail-safe systems or limit switches). Product
users and maintenance personnel should thoroughly review this bulletin
prior to installing, operating or disassembling the actuator.
This publication does not contain information on Flowserve positioners.
Refer to the appropriate installation operation and maintenance
instructions for installing, maintaining, troubleshooting, calibrating and
operating Flowserve positioners.
To avoid possible injury to personnel or damage to valve parts,
WARNING and CAUTION notes must be strictly followed. Modifying this
product, substituting non-factory or inferior parts or using maintenance
procedures other than outlined could drastically affect performance,
void product warranties and be hazardous to personnel and equipment.
0 WARNING: Standard industry safety practices must be
followed when working on this or any process control
product. Specifically, personal protection and lifting devices
must be used as warranted.

Unpacking

While unpacking the actuator, check packing list against materials
received. Lists describing the actuator and accessories are included in
each shipping container.
1. Position the lifting straps and hoist to avoid damage to the tubing
and mounted accessories when lifting the actuator from the
shipping container.
0 WARNING: When lifting an actuator with lifting straps
through the yoke legs, be aware the center of gravity
may be above the lifting point. Therefore, support
must be given to prevent the actuator from rotating or
causing serious injury to personnel or damage to nearby
equipment.
2. Contact your shipper immediately in the event of shipping damage.
3. Contact your Flowserve representative with any problems.

Installation

Prior to installation, make sure adequate overhead clearance for the
actuator is provided to allow for proper removal from the valve body
and for proper maintenance. Refer to Table I.
Table I: Overhead Clearance for Maintenance
Actuator Size
100, 150, 200
NOTE: If an actuator is attached to a valve body assembly, see the
appropriate installation, operation, maintenance instructions.
1. Connect the air supply and instrument signal air lines to the two
marked connections on the positioner. Since both the cylinder
and positioner are suitable for 150 psi (10.3 bar) air supply, an air
regulator should not be used unless the supply exceeds 150 psi
(10.3 bar).
NOTE: In some cases, air supply must be limited to 100 psi
(6.9 bar) rather than 150 psi (10.3 bar); this will be indicated by a
sticker found near the upper air port on the cylinder.
0 WARNING: To avoid personal injury or equipment
damage, do not exceed recommended supply pressure.
2. Installation of an air filter on the supply line is recommended.
3. Use a soap solution to make sure all air connections are leak-free.
