TLV SJH5NB / SJH5VB Free Float Steam Trap with Thermostatic Air Vent

TLV SJH5NB / SJH5VB inline repairable free float steam traps featuring a thermostatic air vent (X-element). Suitable for capacities up to 32 barg in process equipment.

TLV SJH5NB / SJH5VB Free Float Steam Trap with Thermostatic Air Vent

TLV SJH5NB and SJH5VB inline repairable free float steam traps with a thermostatic air vent (X-element) are suitable for a wide range of applications with small-to-large capacities and pressures up to 32 barg, such as heat exchangers, tank heaters, dryers, and process equipment. 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. DO NOT use this product in excess of the maximum operating pressure differential. Such use could make discharge impossible (blocked).

Configuration

The traps are designed for specific installation orientations.

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 trap in the lowest part of the pipeline or equipment so the condensate flows naturally downward into the trap by gravity.
  4. Install the trap within the allowable inclination. Also make sure that the arrow mark on the body corresponds with the direction of flow.
  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 the condensate discharge pipe leads to a tank or recovery line, or whenever the condensate collection pipeline is connected with more than one trap.

Operational Check

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

ConditionDescription
NormalCondensate is discharged continuously with flash steam and the sound of flow can be heard.
BlockedNo condensate is discharged. The trap is quiet and makes no noise, and the surface temperature of the trap is low.
BlowingLive steam continually flows from the outlet and there is a continuous metallic sound.
Steam LeakageLive steam is discharged through the trap outlet together with the condensate and there is a high-pitched sound.
