1 Introduction

1.1 Purpose

This Installation, Operation and Maintenance Manual (IOM) explains how to install and maintain the

B320 bevel gear operator. Information on installation, disassembly, lubrication, and spare parts is

provided.

1.2 User Safety

Safety notices in this manual detail precautions the user must take to reduce the risk of personal

injury and damage to the equipment. The user must read and be familiar with these instructions

before attempting installation, operation, or maintenance. Failure to observe these precautions could

result in serious bodily injury, damage to the equipment, void of the warranty, or operational difﬁculty.

Safety notices are presented in this manual in three forms:

cWARNING: Refers to personal safety. Alerts the user to potential danger. Failure to follow warning

notices could result in personal injury or death.

aCAUTION: Directs the user’s attention to general precautions that, if not followed, could result in

personal injury and/or equipment damage.

NOTE: Highlights information critical to the user’s understanding of the gear operator’s installation

and operation.

Limitorque B320 Series FCD LMENIM3201-02 – 01/15

Designed to make operation of multi-turn valves easier The B320 gear operator makes it easier to both

manually operate multi-turn valves and convert to a motorized service.

Built for reliable valve control — whether manual or motorized The B320 offers torque ranges up to

8,000 ft-lb (10,856 N m) and thrust capacities to 325,000 lb (1,445 kN) for any application

demanding superior strength and accuracy.

Easily adaptable for other applications The B320 is designed to be conﬁgured to each customer’s needs:

• Optional handwheel available for manual actuation

• Add a spur gear attachment for greater mechanical advantage

• Couple with an electric actuator from Limitorque for an economical, motorized, multi-turn package

2.1 Initial Inspection and Storage Instructions

cWARNING: Read this Installation, Operation and Maintenance Manual carefully and completely

before attempting to store the gear operator.

2.3 Inspection and Recording

Upon receipt of the gear operator, inspect the condition of the equipment and record nameplate

information.

1. Carefully remove gear operator from shipping carton or skid. Thoroughly examine the equipment

for any physical damage that may have occurred during shipment. If damaged, immediately

report the damage to the transport company.

2. A nameplate is attached to each gear operator with the following information:

• Operator Size

• Limitorque Order Number

• Ratio

• Serial Number

Record this information for future reference, for ordering parts or obtaining further information.

2.4 Storage Procedure

NOTE: The following is the recommended storage procedure to retain maximum product integrity

during storage. Failure to comply with recommended procedure will void the warranty.

Storage (Less Than One Year)

Operators should be stored in a clean, dry, protected warehouse and should be stored on wooden

skids to protect the machined mounting ﬂange. If the operators must be stored outside, they must be

covered in polyethylene protection with silica gel crystals to absorb moisture. Input shafts should be

rotated every three months to mix lubricant.

4 Installation Instructions

4.1 Safety Precautions

cWARNING: Read this Installation, Operation and Maintenance Manual carefully and completely

before attempting to install, operate, or troubleshoot the Limitorque operator.

cWARNING: Potential HIGH PRESSURE vessel — be aware of high-pressure hazards associated

with the attached valve or other actuated device when installing or performing maintenance

on the operator. Do not remove the operator mounting bolts from the valve or actuated device

unless the valve or device stem is secured or there is no pressure in the line.

cWARNING: For maintenance and/or disassembly of the operator while installed on the valve,

ensure that the operator is not under thrust or torque load. If the valve must be left in service, the

valve stem must be locked in such a way as to prevent any movement of the valve stem.

cWARNING: Do not manually operate the operator with devices other than the installed hand-

wheel. Using force beyond the ratings of the operator and/or using additive force devices such as

cheater bars, wheel wrenches, pipe wrenches, or other devices on the operator handwheel may

cause serious personal injury and/or damage to the operator and valve.

cWARNING: Do not exceed any design limitations or make modiﬁcations to this equipment

without ﬁrst consulting Limitorque.

cWARNING: Use of the product must be suspended any time it fails to operate properly.

aCAUTION: If a motor actuator is driving the manual operator, do not operate the valve under

motor operation without ﬁrst checking and setting the limit switch setting and checking for

correct motor rotation.

aCAUTION: Do not use replacement parts that are not genuine Flowserve Limitorque parts, as

serious personal injury and/or damage to the operator and valve may result.
