TLV J3S-X-RV is a reliable and durable stainless steel bypass blowdown steam trap (free float steam trap with X-element). It is designed to eliminate steam locking on cylinder dryers, presses, and other steam-using equipment prone to steam-locking, while providing continuous, smooth, low velocity condensate discharge as process loads vary.

The trap integrates a regulation valve into the cover, which can be adjusted from 0% to 100% aperture to combat steam locking due to equipment conditions or to perform bypass blowdown to reduce start-up times.

Features

• Integrated Regulation Valve: Aperture of the regulation valve incorporated into the cover can be adjusted to combat steam locking. The valve aperture indicator shows how far open the valve is from 0 to 100%.
• Bypass Blowdown: Regulation valve can be used for bypass blowdown to reduce start-up times.
• Self-Modulating Free Float: Provides continuous, smooth, low velocity condensate discharge.
• Reliable Sealing: Precision-ground float, constant water seal, and three-point seating design ensure a steam-tight seal even under no-load conditions.
• Thermostatic Air Venting: Thermostatic capsule (X-element) with "fail open" feature vents air automatically until close-to-steam temperature.

Discharge Capacities

Steam Trap Discharge Capacity

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.

Bypass Capacity (Regulation Valve)

• Water discharge capacities are based on continuous discharge of water at room temperature (Aperture: 100%) and are applicable for temperatures below 100°C.
• Discharge capacities for steam and water are the values for the regulation valve, not for the X-element. X-element values are not included.

Operating Instructions

Safety 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. Use gloves when operating the regulation valve and keep all body parts well clear of the product.

When using to eliminate steam locking, the steam discharge quantity can be adjusted by using the graph to find out what valve aperture corresponds to your desired steam discharge quantity and differential pressure, then using the valve aperture indication plate to set the valve aperture to the value taken from the graph.

When using the bypass blowdown function, the valve should normally be set to the full open position during use and then returned to the full close position when bypass blowdown is complete.

To adjust the aperture of the regulation valve, turn only the valve operation point at the very top of the valve using the handle (option), a flat-head screwdriver, or open-ended wrench. DO NOT turn the locknut, gland case, or gland retainer nut. Fluid may be discharged under pressure, leading to burns or other injury or damage.
