TLV SJ3V-X Free Float Steam Trap for Vertical Piping

TLV SJ3V-X ductile cast iron free float steam trap for vertical installation. Features three-point seating, thermostatic air venting, and up to 22 barg operating pressure.

TLV SJ3V-X Free Float Steam Trap for Vertical Piping

TLV SJ3V-X is a reliable and durable free float steam trap with tight shut-off, designed for use on small to medium process equipment. This model features a ductile cast iron body and is specifically designed for vertical piping installation.

Features

  1. Self-modulating free float provides continuous, smooth, low velocity condensate discharge as process loads vary.
  2. Precision-ground float, constant water seal and three-point seating design ensure a steam-tight seal, even under no-load conditions.
  3. Thermostatic capsule (X-element) with “fail open” feature vents air automatically until close-to-steam temperature.
  4. Built-in screen with large surface area ensures extended trouble-free operation.
  5. Easy, inline access to internal parts simplifies cleaning and reduces maintenance costs.

Discharge Capacity

TLV SJ3V-X discharge capacity graph

  1. Line numbers within the graph refer to 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.

DANGER

DO NOT use this product under conditions that exceed maximum differential pressure, as condensate backup will occur!
