Repairable
TLV LV13L is a balanced pressure thermostatic steam trap constructed with a brass body, featuring a reliable "fail open" design that prevents condensate from holding back in the steam space. This compact yet high-capacity trap is highly suitable for small processes, tracing lines, vessels, and heaters, accommodating operating pressures up to 13 barg (1.3 MPaG) and temperatures up to 200°C.
Features
- "Fail Open" Design: Will not hold back condensate in the steam space in the event of failure.
- Multi-diaphragm Construction: Ensures long service life and reliable cyclic operation.
- Fixed Subcooling: Operates with fixed subcooling (up to 6°C) throughout the entire pressure range.
- Outstanding Air Venting: Highly sensitive X-element rapidly discharges air and cold condensate at startup.
- Tight Shutoff: Hardened stainless steel "flat valve" and "cone ridge seat" ensure a tight seal.
- Built-in Screen: Features a large surface area for protection against debris.
- Easy Maintenance: Designed to be easy to maintain and clean.

Discharge Capacity
- Differential pressure is the difference between the inlet and outlet pressure of the trap.
- Recommended safety factor: at least 2.
Installation and Maintenance
TIP
The LV13L can be maintained without being removed from the pipeline, provided the surrounding pipes are securely supported. It is installed in pipelines with a horizontal inlet and vertical outlet (cover facing up).
- Before installing the steam trap, blow out the inlet piping to remove all dirt and oil.
- Install the trap in the lowest part of the pipeline or equipment so condensate flows naturally downward into the trap by gravity.
- Ensure a bypass valve is installed to discharge condensate, and inlet and outlet valves to isolate the trap for maintenance.
- When replacing parts with new ones, do not coat threaded portions of the valve seat with anti-seize; tighten to the proper torque (35 N·m for valve seat, 80 N·m for cover).
