TLV JH5RL-X / JH5RL-B / JH5RH-B Cast Steel Free Float Steam Trap

TLV JH5RL-X, JH5RL-B, and JH5RH-B cast steel free float steam traps with thermostatic air venting. Suitable for process equipment up to 80 barg and 425 °C.

TLV JH5RL-X / JH5RL-B / JH5RH-B Cast Steel Free Float Steam Trap

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.

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.
