Flowserve Valtek Spring Cylinder Rotary Actuators Manual de usuario descargar pdf

This bulletin contains instructions on maintaining the

clamping and non-clamping splined lever design.

Contact the factory or your Flowserve representative for

more information on the diaphragm seal assembly design.

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 parts, or

using maintenance procedures other than

outlined could void warranties, drastically

affect performance and be hazardous to

personnel and equipment.

Unpacking

1. While unpacking the actuator, check the packing

list against the materials received.

2. When lifting the actuator from the shipping container,

position lifting straps and hoist to avoid damage to

tubing and mounted accessories.

WARNING: When lifting an actuator with lifting

straps, be aware the center of gravity may be

above the lifting point. Therefore, support must

be given to prevent the actuator from rotating.

Failure to do so can cause serious injury to

personnel and damage to actuator or nearby

equipment.

3. Contact your shipper immediately for any shipping

damage.

4. Contact your Flowserve representative for any

problems.

GENERAL INFORMATION

The following instructions are designed to assist in

unpacking, installing and performing maintenance as

required on Valtek

Spring Cylinder Rotary Actuators.

Product users and maintenance personnel should

thoroughly review this bulletin prior to installing, oper-

ating or performing any maintenance on the actuator.

Separate maintenance instructions cover additional

components (such as Valdisk and ShearStream body

assemblies, fail-safe systems, limit switches, hand-levers,

position transmitters and handwheels.

This publication does not contain information on

Flowserve positioners. Refer to the appropriate main-

tenance bulletin for installing, calibrating, maintaining,

troubleshooting and operating Flowserve positioners.

IMPORTANT

Three designs of the Spring Cylinder Rotary Actuator

exist in service today. The original design contained a

diaphragm seal assembly in the actuator. This assembly

was later replaced with a sliding seal assembly. Life-

cycle testing under rigorous conditions shows sliding

seals will last many times longer than diaphragm stem

seals. Made of Delrin 100 and bronze, sliding seals are

durable and much easier to maintain. Since the sliding

seal design has replaced the diaphragm as Flowserve’s

standard, it is highly recommended that the diaphragm

stem seal be replaced with the sliding seal.

The third design uses a standard rotary actuator with

a sliding seal assembly in the actuator and a clamping

lever arm in the transfer case.

Maintenance personnel should become familiar with

the particular rotary actuator design needing service

and follow the appropriate maintenance instructions for

that design.
