TLV J3S-X free float steam trap with thermostatic air vent (X-element) is suitable for a wide range of applications up to 2.1 MPaG (300 psig), such as tracer lines, unit and process heaters, heating coils, and heat exchangers.

The J3S-X S1 and J3S-X S2 steam traps with thermostatic air venting (X-element) are designed especially for use in rubber vulcanizer applications up to 1.4 MPaG (200 psig). They feature a cover plug for retrofitting a lock release valve against steam locking, a drain plug for installing a blowdown valve, and an internal screen with (S2) or without (S1) wire mesh. The traps discharge condensate continuously and automatically, at a temperature slightly lower than saturation temperature.

Safety Considerations

DANGER

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.

WARNING

• Install properly and DO NOT use this product outside the recommended operating pressure, temperature and other specification ranges. Improper use may result in damage or malfunctions.
• DO NOT use this product in excess of the maximum operating pressure differential. Such use could make discharge impossible.
• DO NOT subject this product to condensate loads that exceed its discharge capacity.
• Take measures to prevent people from coming into direct contact with product outlets.
• 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.

INFO

• Maximum allowable pressure (PMA) and maximum allowable temperature (TMA) are PRESSURE SHELL DESIGN CONDITIONS, NOT OPERATING CONDITIONS. ** "Valve No." is displayed for products with options. This item is omitted from the nameplate when there are no options.

Proper Installation

WARNING

Installation, inspection, maintenance, repairs, disassembly, adjustment and valve opening/closing should be carried out only by trained maintenance personnel.

• Take measures to prevent people from coming into direct contact with product outlets.
• Do not use excessive force when connecting threaded pipes.
• Install for use under conditions in which no freeze-up will occur.
• Install for use under conditions in which no water hammer will occur.

1. Before installation, be sure to remove all protective seals.
2. Before installing the trap, blow out the inlet piping to remove all dirt and oil.
3. Install the steam trap within the allowable inclination. Also make sure that the arrow mark on the body corresponds with the direction of flow.
4. Install the trap in the lowest part of the pipeline or equipment so the condensate flows naturally into the trap by gravity. The inlet pipe should be as short and have as few bends as possible.
5. Support the pipes properly within 800 mm (2.5 ft) on either side of the trap.
6. Install a bypass valve to discharge condensate, and inlet and outlet valves to isolate the trap in the event of trap failure or when performing maintenance.
7. Install a check valve at the trap outlet whenever more than one trap is connected to the condensate collection pipeline.
8. The use of unions is recommended to facilitate connection and disconnection of screwed models.

Allowable Inclination:

Piping Arrangement

Check to make sure that the pipes connected to the trap have been installed properly:

1. Is the pipe diameter suitable?
2. Has the trap been installed within the allowable inclination and with the arrow on the body pointing in the direction of flow?
3. Has sufficient space been secured for maintenance?
4. Have maintenance valves been installed at inlet and outlet? If the outlet is subject to back pressure, has a check valve been installed?
5. Is the inlet pipe as short as possible, with as few bends as possible, and installed so that the condensate will flow naturally down into the trap?

Inspection and Maintenance

Operational inspections should be performed at least twice per year, or as called for by trap operating conditions. Steam trap failure may result in a temperature drop in the equipment, poor product quality or losses due to steam leakage.

DANGER

NEVER apply direct heat to the float. The float may explode due to increased internal pressure, causing accidents leading to serious injury or property and equipment damage.

Parts Inspection Procedure

Part	Procedure
Body, Cover	Check inside for damage, dirt, grease, oil film, rust or scale
Gaskets	Check for warping or damage
X-element	Check for damage
Screen	Check for clogging, corrosion or damage
Float	Check for deformation, damage, oil film or water inside
Air Vent Valve Seat, Orifice	Check for rust, scale, oil film, wear or damage

Troubleshooting

If the expected performance is unachievable after installation of the steam trap, check the following points to take appropriate corrective measures.

Problem	Cause	Remedy
No condensate is discharged (blocked) or discharge is poor	Float is damaged or filled with condensate	Replace the float
	Orifice, screen or piping is clogged with rust or scale	Clean
	Steam-locking has occurred	Blowdown through the bypass or close the trap inlet valve and allow the trap to cool
	X-element is damaged	Replace the X-element
	The trap operating pressure exceeds the maximum specified pressure, or there is insufficient pressure differential	Compare specifications and actual operating conditions
Steam is discharged or leaks from the trap outlet (blowing)	Rust and scale have accumulated around the orifice or under the float	Clean
	Orifice is damaged	Replace the orifice
	Float is deformed or coated with scale	Clean or replace the float
	Trap is installed above the maximum allowable inclination angle	Correct the installation
	Vibration of trap occurs	Lengthen inlet piping, then fasten it securely
	The X-element is damaged, or clogged with rust or scale	Clean or replace the X-element

Lock Release Valve (Option: J3S-LR/J5S-LR/J6S-LR)

WARNING

Use heat-resistant gloves when operating the lock release valve and keep all body parts well clear of the product. Failure to do so could result in burns, other injury or damage from the blowing of small amounts of steam and condensate.

Note: Use of the lock release valve puts pressure on the X-element, and may reduce condensate discharge capacity. For more details, contact TLV.

Use on equipment where steam locking/air binding, which slows the discharge of condensate and reduces equipment efficiency, tends to occur (cylindrical dryers, air fin heater, etc.).

1. When the product is shipped from the factory, the element retainer is raised in the maximum, valve-closed position.
2. Before operating the lock release valve, examine the trap outlet and confirm that the trap is functioning properly.
3. Operate the lock release valve using a flat-head screwdriver.

J3S-X S1 / J3S-X S2

The S series feature a built-in screen:

• J3S-X S1: without wire mesh
• J3S-X S2: with wire mesh

A special H-type X-element is used for the S series (a B-type X-element is equipped on the Standard J3S-X). This X-element is for venting air not only at batch run startup, but also during operation, preventing temperature drops. In addition, it ensures secure sealing.

A drain plug at the bottom of the body is equipped as standard. By removing the plug and installing an automatic or manual valve, condensate blowdown can be carried out when the steam-using equipment experiences a temperature drop.
