TLV JH7RL-X inline repairable JH-X series steam traps with thermostatic air vent (X-element) are suitable for a wide range of applications with small-to-large capacities and pressures up to 3.2 MPaG (450 psig), such as all kinds of heat exchangers, process heaters and coils. The traps discharge condensate continuously and automatically, at a temperature slightly lower than saturation temperature. (1 MPa = 10.197 kg/cm², 1 bar = 0.1 MPa)

1. Safety Considerations

WARNING

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.

DANGER

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.

• Installation, inspection, maintenance, repairs, disassembly, adjustment and valve opening/closing should be carried out only by trained maintenance personnel.
• DO NOT use this product in excess of the maximum operating pressure differential. Such use could make discharge impossible.
• Use hoisting equipment for heavy objects (weighing approximately 20 kg (44 lb) or more).
• Use the eyebolts for removing the cover only; DO NOT use the eyebolts for hoisting the product.
• 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.

3. Specifications

INFO

Maximum allowable pressure (PMA) and maximum allowable temperature (TMA) are PRESSURE SHELL DESIGN CONDITIONS, NOT OPERATING CONDITIONS.

To avoid malfunctions, product damage, accidents or serious injury, install properly and DO NOT use this product outside the specification range. Local regulations may restrict the use of this product to below the conditions quoted.

4. Proper Installation

• 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. 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, as shown below. 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.

5. Piping Arrangement

Requirement	Correct Execution	Incorrect Execution
Install a catchpot with the proper diameter.	Diameter is properly sized to handle condensate load.	Diameter is too small.
Make sure the flow of condensate is not obstructed.	Unobstructed piping path directly to the trap.	Diameter is too small and inlet protrudes into pipe.
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 directly into the trap with the condensate.
Blind end installations.	Make sure nothing obstructs the flow of condensate into the trap.	Condensate collects in the pipe without reaching the trap.

6. 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.

Parts	Inspection Procedure
Body, Cover(s)	Check inside for damage, dirt, grease, oil film, rust or scale
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

7. Maintenance Parts and Repair Parts

Maintenance parts and repair parts are available from TLV in kits. Maintenance Kits (M) generally include items like Cover Gasket, Orifice Gasket, and Plug Gasket. Repair Kits (R) typically include the Orifice, Float, and specialized replacement elements in addition to the gaskets.

8. 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.

Condition	Indicator
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.

9. Troubleshooting

If the expected performance is unachievable after installation of the steam trap, check the following points for 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 are clogged with rust or scale	Clean
	X-element is damaged	Replace the X-element
	Operating pressure exceeds max specified pressure, or insufficient differential pressure	Compare specifications and actual operating conditions
	Steam locking has occurred	Blowdown through bypass or close inlet valve to cool
Steam is discharged or leaks from outlet (blowing/leakage)	Rust and scale accumulated around orifice or under float	Clean
	Orifice is damaged	Replace with new orifice
	Float is deformed or coated with scale	Clean or replace the float
	Trap installed above maximum allowable inclination angle	Correct the installation
	Vibration of trap occurs	Lengthen inlet piping, fasten securely
	X-element is damaged, or clogged with rust/scale	Clean or replace the X-element
Steam leaks from other locations	Gaskets deteriorated or damaged	Replace with new gaskets
	Improper tightening torques	Tighten to proper torque
	Valve body or cover is corroded	Replace the trap
Float is frequently damaged	Water hammer occurs	Check piping to correct water hammer causes
