The TLV J5S-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 trap discharges condensate continuously and automatically, at a temperature slightly lower than saturation temperature.

Related Models

The source manual also covers related models J3S-X and J6S-X (up to 2.1 MPaG), as well as J3S-X S1 and J3S-X S2 which are designed for rubber vulcanizer applications up to 1.4 MPaG (200 psig).

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

Configuration

Key components include the Body, Cover, Float, Orifice Plug, Orifice, X-element, and Air Vent Valve Seat. (Refer to the product nameplate for detailed specifications. Maximum allowable pressure (PMA) and maximum allowable temperature (TMA) are pressure shell design conditions, not operating conditions.)

Proper Installation

TIP

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

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, as shown below. 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.

Allowable Inclination

Piping Arrangement

Requirement	Correct	Incorrect
Catchpot	Install a catchpot with the proper diameter.	Diameter is too small.
Condensate Flow	Make sure the flow of condensate is not obstructed.	Diameter is too small and inlet protrudes into pipe.
Inlet Pipe Connection	To prevent rust and scale from flowing into the trap, connect the inlet pipe 25-50 mm (1-2 in.) above the base of the T-pipe.	Rust and scale flow into the trap with the condensate.
Blind End Installation	When installing on the blind end, make sure nothing obstructs the flow of condensate.	Condensate collects in the pipe.

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.

Operational Check

Status	Description
Normal	Condensate is discharged continuously with flash steam and the sound of flow can be heard. If there is very little condensate, there is almost no sound of flow.
Blocked	No condensate is discharged. The trap is quiet and makes no noise, and the surface temperature of the trap is low.
Blowing	Live steam continually flows from the outlet and there is a continuous metallic sound.
Steam Leakage	Live steam is discharged through the trap outlet together with the condensate and there is a high-pitched sound.

(When conducting a visual inspection, flash steam is sometimes mistaken for steam leakage. For this reason, the use of a steam trap diagnostic instrument is highly recommended.)
