The TLV JH5RL-X, JH5RL-B, and JH5RH-B are reliable and durable cast steel free float steam traps designed for use on small to medium-size process equipment. The JH5RL-B and JH5RH-B models are also suitable for both superheated and high-pressure process equipment. They feature a self-modulating free float that provides continuous, smooth, low-velocity condensate discharge as process loads vary.

Key features include a precision-ground float, constant water seal, and three-point seating design that ensure a steam-tight seal, even under no-load conditions. With only one moving part—the free float—concentrated wear is prevented, providing a long maintenance-free service life. The JH5RL-X utilizes a thermostatic capsule (X-element) with a "fail open" feature that vents air automatically at close-to-steam temperature. The JH5RL-B and JH5RH-B utilize a thermostatic bimetal air vent valve for rapid startup. All models feature a built-in screen with a large surface area and allow easy, inline access to internal parts to simplify cleaning and reduce maintenance costs.

Discharge Capacity

JH5RL-B / JH5RH-B

INFO

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. Capacities are based on continuous discharge of condensate 6 °C below saturated steam temperature.
4. Recommended safety factor: at least 1.5.

Proper Installation

WARNING

Installation, inspection, maintenance, repairs, disassembly, adjustment and valve opening/closing should be carried out only by trained maintenance personnel. Use the eyebolts for removing the cover only; DO NOT use the eyebolts for hoisting the product.

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. When hoisting the product, hang the rope around the inlet/outlet as close to the body as possible.
4. Install the steam trap within the allowable inclination. Also make sure that the arrow mark on the body corresponds with the direction of flow.
5. 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.
6. Support the pipes properly within 800 mm (2.5 ft) on either side of the trap.
7. 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.
8. Install a check valve at the trap outlet whenever more than one trap is connected to the condensate collection pipeline.
9. The use of unions is recommended to facilitate connection and disconnection of screwed models.

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.

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

Gaskets	Check for warping or damage
X-element	Check for damage
Screen(s)	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

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
