TLV JLH15 is an extremely durable, inline-repairable, compact high-capacity cast steel float steam trap with thermostatic air venting, designed for large process or heating equipment. With the unique sensitivity of mechanical steam traps for condensate discharge, the trap reduces the time required to start up process equipment and improves heating efficiency.

Features

• Double-seated valve with heat-treat hardened valve seat and valve head provides continuous, smooth, low-velocity condensate discharge as process loads vary.
• Self-aligning valve mechanism with stainless steel internals minimizes wear.
• Thermostatic bimetal air vent valve vents air automatically for rapid startup.
• Easy, inline access to internal parts simplifies cleaning and reduces maintenance costs.
• High-quality stainless steel internals and hardened valve surfaces ensure reliability.
• Built-in screen eliminates the need for an external strainer.

Discharge Capacity

Notes:

1. Differential pressure is the difference between the inlet and outlet pressure of the trap.
2. Capacities are based on continuous discharge of condensate 6 °C below saturated steam temperature.
3. Recommended safety factor: at least 1.5.

Installation and Maintenance

Installation Guidelines

• The product should be inclined no more than 5° horizontally and front-to-back.
• Install the product so the arrow on the body is pointing in the direction of condensate flow.
• Ensure sufficient maintenance space: 400 mm or more above the cover, and 200 mm or more on the side.

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.
