The TLV JH3S-X is a reliable and durable stainless steel inline repairable free float steam trap with thermostatic air venting (X-element). It is suitable for a wide range of applications with small-to-large capacities and pressures up to 32 barg (3.2 MPaG), such as all kinds of heat exchangers, process heaters, and coils. The trap discharges condensate continuously and automatically at a temperature slightly lower than saturation temperature, utilizing a self-modulating free float that provides smooth, low-velocity discharge as process loads vary.

A precision-ground float, constant water seal, and three-point seating design ensure a steam-tight seal even under no-load conditions. The thermostatic capsule (X-element) features a "fail open" design that vents air automatically at close-to-steam temperature, ensuring rapid startup and extended trouble-free operation. Easy inline access to internal parts simplifies cleaning and reduces maintenance costs.

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.

WARNING

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. Disassembling or removing the product when it is hot or under pressure may lead to discharge of fluids, causing burns, other injuries or damage.

Note: Maximum Allowable Pressure (PMA) is 32 barg. Maximum Allowable Temperature (TMA) is 350 °C. These are pressure shell design conditions, not operating conditions.

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 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.

Allowable Inclination

Inspection and Maintenance

Operational inspections should be performed at least twice per year, or as called for by trap operating conditions.

Operational Check

• 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.
