The TLV J6S-X is a reliable and durable stainless steel free float steam trap with three-point seating and thermostatic air venting. Designed for use on medium-size process equipment, tracer lines, unit and process heaters, heating coils, and heat exchangers, it provides tight shut-off and continuous condensate discharge. The trap discharges condensate continuously and automatically at a temperature slightly lower than saturation temperature, accommodating applications up to 2.1 MPaG (300 psig).

Key features include:

• Self-modulating free float provides continuous, smooth, low velocity condensate discharge as process loads vary.
• Precision-ground float, constant water seal, and three-point seating design ensure a steam-tight seal, even under no-load conditions.
• Only one moving part, the free float, prevents concentrated wear and provides a long maintenance-free service life.
• Thermostatic capsule (X-element) with "fail open" feature vents air automatically until close-to-steam temperature.
• Built-in screen with large surface area ensures extended trouble-free operation.
• Easy, inline access to internal parts simplifies cleaning and reduces maintenance costs.

Installation and Piping

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, 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.
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

Requirement	Correct	Incorrect	Reason
Install a catchpot with the proper diameter.			Diameter is too small.
Make sure the flow of condensate is not obstructed.			Diameter is too small and inlet protrudes into pipe.
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.
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.

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.

WARNING

• Before attempting to open the trap, close the inlet and outlet isolation valves and wait until the trap has cooled completely. Failure to do so may result in burns.
• Be sure to use the proper components and NEVER attempt to modify the product.

Instructions for Plug / Holder Disassembly and Reassembly

The seal on the threaded plugs/holders found on TLV products is formed by a flat metal gasket. There are various installation orientations for the gaskets, such as horizontal, diagonal and downward, and the gasket may be pinched in the thread recesses during assembly.

1. Remove the plug/holder using a tool of the specified size.
2. The gasket should not be reused. Be sure to replace it with a new gasket.
3. Clean the gasket surfaces of the plug/holder and the product body using a rag and/or cleaning agents, then check to make sure the surfaces are not scratched or deformed.
4. Coat both the gasket surface of the plug/holder and the threads of the plug/holder with anti-seize, then press the gasket onto the center of the gasket surface of the plug/holder, making sure the anti-seize affixes the gasket tightly to the plug/holder. Check to make sure the gasket is not caught in the recesses of the threads.
5. Hold the plug/holder upside down to make sure that the anti-seize makes the gasket stick to the plug/holder even when the plug/holder is held upside down.
6. Screw the plug/holder by hand into the product body while making sure that the gasket remains tightly affixed to the center of the gasket surface of the plug/holder. Make sure the entire gasket is making contact with the gasket surface of the product body. It is important at this point to make sure the gasket is not pinched in the thread recesses of the plug/holder.
7. Tighten the plug/holder to the proper torque.
8. Next, begin the supply of steam and check to make sure there is no leakage from the part just tightened. If there is leakage, immediately close the inlet valve and, if there is a bypass valve, take the necessary steps to release any residual pressure. After the surface of the product cools to room temperature, repeat the procedure beginning from step 1.

Operational Check

A visual inspection can be carried out to aid in determining the necessity for immediate maintenance or repair, if the trap is open to atmosphere. If the trap does not discharge to atmosphere, use diagnostic equipment such as TLV TrapMan or TLV Pocket TrapMan.

• 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.)

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 between the trap inlet and outlet	Compare specifications and actual operating conditions
Steam is discharged or leaks from the trap outlet (blowing) (steam leakage)	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
Steam leaks from a place other than the trap outlet	Deterioration of or damage to gaskets	Replace with new gaskets
	Improper tightening torque for cover was used	Tighten to the proper torque
Float is frequently damaged	Water hammer occurs	Examine the piping for problems that can cause water hammer

Lock Release Valve (Option: 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.

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 as follows (tools required: flat-head screwdriver):
   • To Open: Insert the screwdriver into the slot on the top of the element retainer and slowly turn clockwise. (Do not turn the element retainer past the point at which it stops.)
   • To Close: Insert the screwdriver into the slot on the top of the element retainer and close by turning counterclockwise. Raise the element retainer until the spring pin contacts the bottom of the gland case. (Do not turn the element retainer past the point at which it stops.)
4. If steam should leak from the gland retainer nut or gland case, it can be stopped by further tightening the gland retainer nut. (Do not over tighten, otherwise element retainer may seize and become unworkable.)
