TLV JH5SL-X, JH5SL-B, and JH5SH-B are inline repairable stainless steel free float steam traps with thermostatic air venting. They are suitable for a wide range of applications with small-to-medium capacities and pressures up to 6.5 MPaG (JH5SH-B), such as heat exchangers, process heaters, and coils. The traps discharge condensate continuously and automatically, at a temperature slightly lower than saturation temperature.

Features

1. Self-modulating free float provides continuous, smooth, low-velocity condensate discharge as process loads vary.
2. Precision-ground float, constant water seal and three-point seating design ensure a steam-tight seal, even under no-load conditions.
3. JH5SL-X: Thermostatic capsule (X-element) with "fail open" feature vents air automatically at close-to-steam temperature.
4. JH5SL-B/JH5SH-B: Thermostatic bimetal air vent valve vents air automatically for rapid startup.
5. Built-in screen with large surface area ensures extended trouble-free operation.
6. Easy, inline access to internal parts simplifies cleaning and reduces maintenance costs.

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 such hazards as damage to the product or malfunctions, which may lead to serious accidents.
• DO NOT use this product in excess of the maximum operating pressure differential. Such use could make discharge impossible.
• 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.
• Be sure to use only the recommended components when repairing the product, and NEVER attempt to modify the product in any way.
• Use only under conditions in which no freeze-up will occur.
• Use under conditions in which no water hammer will occur.

Notes:

1. Line numbers within the graph are orifice numbers.
2. Differential pressure is the difference between the inlet and outlet pressure of the trap.
3. Recommended safety factor: at least 1.5.

Proper Installation

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.

Allowable Inclination

Piping Arrangement

Requirement	Correct	Incorrect
Install a catchpot with the proper diameter.	Diameter is sufficient.	Diameter is too small.
Make sure the flow of condensate is not obstructed.	Flow is clear.	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.	Connected above base.	Rust and scale flow into the trap with the condensate.
When installing on the blind end, make sure nothing obstructs the flow of condensate.	Flow is clear.	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 temperature drop in the equipment, poor product quality or losses due to steam leakage.

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.

• 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.

Troubleshooting

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 are clogged with rust or scale	Clean
	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 locking has occurred	Blowdown through the bypass or close the trap inlet valve and allow the trap to cool
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 with new 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 the gaskets
	Leakage from eroded cavities of body or cover	Replace the trap
	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
