Introduction

Thank you for purchasing the TLV S-COS/S-COSR pressure reducing valve for steam.

This product has been thoroughly inspected before being shipped from the factory. When

the product is delivered, before doing anything else, check the specifications and external

appearance to make sure nothing is out of the ordinary. Also be sure to read this manual

carefully before use and follow the instructions to be sure of using the product properly.

Steam-using equipment can achieve its intended efficiency only if the steam being used is

very dry. Using steam in which matter such as condensate, scale, types of grease or air is

entrained can result not only in problems with the steam-using equipment and in lowered

productivity, but can also lead to shortened service life for and malfunction of the pressure

reducing valves. The TLV S-COS, with a built-in separator and steam trap, eliminates these

problems and makes possible the supply of very dry steam at a constant pressure. Both

the TLV S-COS and S-COSR provide a more stable secondary pressure than conventional

pressure reducing valves. They are designed for long service life, with all major componets

made of stainless steel for superior durability.

If detailed instructions for special order specifications or options not contained in this manual

are required, please contact TLV for full details.

This instruction manual is intended for use with the model(s) listed on the front cover.

It is needed not only for installation, but also for subsequent maintenance, disassembly/

reassembly and troubleshooting. Please keep it in a safe place for future reference.

Safety Considerations

• Read this section carefully before use and be sure to follow the instructions.

• Installation, inspection, maintenance, repairs, disassembly, adjustment and valve opening/

closing should be carried out only by trained maintenance personnel.

• The precautions listed in this manual are designed to ensure safety and prevent equipment

damage and personal injury. For situations that may occur as a result of erroneous handling,

three different types of cautionary items are used to indicate the degree of urgency and the

scale of potential damage and danger: DANGER, WARNING and CAUTION.

• The three types of cautionary items above are very important for safety: be sure to observe

all of them as they relate to installation, use, maintenance and repair. Furthermore, TLV

accepts no responsibility for any accidents or damage occurring as a result of failure to

observe these precautions.

Cautionary items and definitions

Warning

Indicates that there is a potential threat of death or serious injury

Caution

Indicates that there is a possibility of injury or equipment/product damage

Safety considerations for the product

Warning

NEVER apply direct heat to the float. The float may explode due to increased internal pressure,

causing accidents leading to serious injury or damage to property and equipment.

Caution

Install properly and DO NOT use this product outside the recommended operating

pressure, temperature and other specification ranges. Improper use may result in such

hazards as damage to the product or malfunctions that may lead to serious accidents. Local

regulations may restrict the use of this product to below the conditions quoted.

Caution

DO NOT use the product in excess of the maximum operating pressure differential. Such

use could make discharge through the steam trap impossible (blocked).

Caution

Take measures to prevent people from coming into direct contact with product outlets.

Failure to do so may result in burns or other injury from the discharge of fluids.

Caution

When disassembling or removing the product, wait until the internal pressure equals

atmospheric pressure and the surface of the product has cooled to room temperature.

Disassembling or removing the product when it is hot or under pressure may lead to discharge of

fluids, causing burns, other injuries or damage.

Caution

Be sure to use only the recommended components when repairing the product, and NEVER

attempt to modify the product in any way. Failure to observe these precautions may result in

damage to the product and burns or other injury due to malfunction or the discharge of fluids.

Caution

Do not use excessive force when connecting threaded pipes to the product. Over-tightening

may cause breakage leading to fluid discharge, which may cause burns or other injury.

Caution

Use only under conditions in which no freeze-up will occur. Freezing may damage the

product, leading to fluid discharge, which may cause burns or other injury.

Caution

Use only under conditions in which no water hammer will occur. The impact of water hammer

may damage the product, leading to fluid discharge, which may cause burns or other injury.
