TLV JL14-X and JLH14-X are extremely durable, inline-repairable, high-capacity float steam traps with thermostatic air venting, designed for large process or heating equipment. The series includes the cast iron JL14-X and cast steel JLH14-X, capable of handling maximum operating pressures of up to 32 barg and temperatures up to 240 °C (or 400 °C with the optional bimetal air vent unit).

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 capsule (X-element) with “fail open” feature vents air automatically until close-to-steam temperature.
• Easy, inline access to internal parts simplifies cleaning and reduces maintenance costs.
• High-quality stainless steel internals and hardened valve surfaces ensure reliability.

DANGER

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

Installation and Piping Checks

INFO

Sample Installation Requirements:

• Install a bypass valve and inlet and outlet isolation valves for use in the event of trap failure or when performing maintenance.
• Install a strainer (40 to 60 mesh) ahead of the product.
• The product should be inclined no more than 5° horizontally and front-to-back. Leave adequate clearance for a maintenance space (at least 300 mm) above the trap cover.
• Connect outlet piping. Be sure to size outlet piping large enough to accommodate any flash steam that may form to prevent any increase in back pressure and allow at least 1 m straight piping to avoid possible pipe erosion.
