Installation & Maintenance Instructions for

Marwin 4700 Series Three Piece Ball Valves

Warning: Marwin Valve Ball Valves must only be used, installed and repaired in accordance with these Installation &

Maintenance Instructions. Observe all applicable public and company codes and regulations. In the event of leakage or

other malfunction, call a qualiﬁed service person; continued operation may cause system failure or a general hazard.

Please read these instructions carefully!

Your Marwin Valve product will provide you with long,

trouble-free service if it is correctly installed and main-

tained. Spending a few minutes now reading these in-

structions can save hours of trouble and downtime later.

When making repairs, use only genuine Marwin Valve

parts, available for immediate shipment from the factory.

Scope

This manual is intended as a guide to assist customers in

the storage, installation, and maintenance of

Marwin 1/2" - 4" 4700 and 1/2" - 2" CV4700 Series

ball valves. Subsequent additions or special instructions

will be provided for special valves, critical service or cus-

tomer requirements.

Applicability

This manual is applicable to the 4700 Series Marwin three

piece ball valves.

Caution

To help prevent injury to personnel or damage to equip-

ment, please read this section completely before per-

forming any operations.

1. Valve pressure ratings are based on many vari-

ables, including valve series and size, as well as

body, seat and bolt material. Verify that application

does not exceed the pressure or temperature rat-

ing on the nameplate.

2. ALWAYS depressurize the line with the valve in the

OPEN position before disassembly. Cycle valve in

depressurized line before removing valve.

3. Wear protective equipment and take appropriate

precautions to safeguard against injury caused by

the discharge of trapped ﬂuids.

4. Use only Marwin recommended spare parts for

maintenance.

5. To ensure safety and maintain warranty, never

modify valve in any way without prior approval from

Marwin.

Storage

A petroleum-based oil (silicone free) is used as lubrica-

tion on all internal surfaces. This may be removed with a

solvent if found objectionable. All valves are adequately

packed in a strong cardboard case in such a way as to

avoid any possible damage during transport and storage.

Caution: if ball valves are not destined for immediate

use, the following precautions should be taken:

1. If possible, leave the ball valves in their packing

cases during the period of storage.

2. Ball valves must remain in open position during this time.

3. In order to prevent damage, protective plastic

covers on valve ends should not be removed until

immediately prior to installation.

4. It is advisable to store the valves in waterproof

conditions. Ball valves should be protected to safe-

guard against humidity, moisture, dust, dirt sand,

mud, salt spray and seawater.

5. All valves complete with actuators are to be stored

in dry conditions.

6. Valves to be stored for a long period of time should

be checked by the quality control personnel every

six months; every three months when valves are

automated.

Maintenance During Storage Period

 Internal surface should be inspected to check for

dust or other foreign objects.

 Rust or dust must be removed by cleaning with

proper solvent.

 After cleaning, ball valves must be lubricated with

an adequate lubricant.
