TLV SH5NL is an inline repairable free float steam trap with a thermostatic air vent. It is suitable for applications with pressures up to 10 MPaG (1500 psig), temperatures up to 425 °C (800 °F), and under superheat conditions. The traps discharge condensate continuously and automatically at a temperature slightly lower than saturation temperature.

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.

Specifications

Refer to the product nameplate for detailed specifications.

Proper Installation

1. Before installation, be sure to remove all protective seals.
2. Install the trap within the allowable inclination, as shown below. Also make sure that the arrow mark on the body corresponds with the direction of flow.
3. Before installing the trap, blow out the inlet piping to remove all dirt and oil.
4. Install the trap in the lowest part of the pipeline or equipment so the condensate flows naturally downward 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 0.8 meters (2.5 ft.) on either side of the trap.

Allowable Inclination

The face of the screen holder perpendicular to the ground, and the inlet and outlet horizontal to the ground.

Piping Arrangement

Check to make sure that the pipes connected to the trap have been installed properly.

• Is the pipe diameter suitable?
• Has the trap been installed within the allowable inclination and with the arrow on the body pointing in the direction of flow?
• Has sufficient space been secured for maintenance?
• Have maintenance valves been installed at inlet and outlet? If the outlet is subject to back pressure, has a check valve been installed?

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.

Parts Inspection Procedure

Part	Inspection
Body, Cover	Check inside for damage, dirt, grease, oil film, rust or scale
Gaskets	Check for warping or damage
Air Vent Strip	Check for damage
Screen	Check for clogging, corrosion or damage
Float	Check for deformation, damage, oil film or water inside
Orifice	Check for rust, scale, oil film, wear or damage

Exploded View

Operational Check

A visual inspection can be carried out to aid in determining the necessity for immediate maintenance or repair.

• Normal: Condensate is discharged continuously with flash steam and the sound of flow can be heard.
• 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.
