The TLV JH7RH-P is a reliable and durable low alloy cast steel free float steam trap for use on medium-size process equipment, suitable for both superheated and extremely high-pressure applications. Instead of a bimetal air vent, it is manufactured with a cover threaded plug for higher pressure and temperature applications. The inline repairable design features a self-modulating free float that provides continuous, smooth, low-velocity condensate discharge as process loads vary, along with a precision-ground float, constant water seal, and three-point seating design that ensures a steam-tight seal even under no-load conditions.

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.

WARNING

To avoid malfunctions, product damage, accidents or serious injury, install properly and DO NOT use this product outside the specifications' range. DO NOT use traps under conditions that exceed maximum differential pressure, as condensate backup will occur!

Proper Installation

• Installation, inspection, maintenance, repairs, disassembly, adjustment and valve opening/closing should be carried out only by trained maintenance personnel.
• Install for use under conditions in which no freeze-up will occur.
• Install for use under conditions in which no water hammer will occur.

1. Before installation, be sure to remove all protective seals.
2. Before installing the trap, blow out the inlet piping to remove all dirt and oil.
3. When hoisting the product, hang the rope around the inlet/outlet as close to the body as possible.
4. Install the steam trap within the allowable inclination, as shown below. Also make sure that the arrow mark on the body corresponds with the direction of flow.

Allowable Inclination

Piping Arrangement

Check to make sure that the pipes connected to the trap have been installed properly.

1. Is the pipe diameter suitable?
2. Has the trap been installed within the allowable inclination and with the arrow on the body pointing in the direction of flow?
3. Has sufficient space been secured for maintenance?
4. Have maintenance valves been installed at inlet and outlet? If the outlet is subject to back pressure, has a check valve been installed?
5. Is the inlet pipe as short as possible, with as few bends as possible, and installed so that the condensate will flow naturally down into the trap?

Inspection and Maintenance

Operational inspections should be performed at least twice per year, or as called for by trap operating conditions.

Parts Inspection Procedure
Body, Cover(s)	Check inside for damage, dirt, grease, oil film, rust or scale
Gaskets	Check for warping or damage
Screen	Check for clogging, corrosion or damage
Float	Check for deformation, damage, oil film or water inside
Valve Seat	Check for rust, scale, oil film, wear or damage

Instructions for Plug / Holder Disassembly and Reassembly

The seal on the threaded plugs/holders found on TLV products is formed by a flat metal gasket.

1. Remove the plug/holder using a tool of the specified size.
2. The gasket should not be reused. Be sure to replace it with a new gasket.
3. Clean the gasket surfaces of the plug/holder and the product body.
4. Coat both the gasket surface of the plug/holder and the threads of the plug/holder with anti-seize.
5. Hold the plug/holder upside down to make sure that the anti-seize makes the gasket stick.
6. Screw the plug/holder by hand into the product body while making sure that the gasket remains tightly affixed.

Operational Check

A visual inspection can be carried out to aid in determining the necessity for immediate maintenance or repair.

Condition	Description
Normal	Condensate is discharged continuously with flash steam and the sound of flow can be heard.
Blocked	No condensate is discharged. The trap is quiet and makes no noise, and the surface temperature of the trap is low.
Blowing	Live steam continually flows from the outlet and there is a continuous metallic sound.
Steam Leakage	Live steam is discharged through the trap outlet together with the condensate and there is a high-pitched sound.

Flash steam (White jet with water droplets):

Live steam leakage (Clear, slightly bluish jet):

Troubleshooting

Problem	Cause	Remedy
No condensate is discharged (blocked) or discharge is poor	Float is damaged or filled with condensate	Replace the float
	Orifice, screen or piping are clogged with rust or scale	Clean
	Steam-locking has occurred	Blowdown through the bypass or close the trap inlet valve and allow the trap to cool
	Flow exceeds rated capacity of the trap	Check specifications and reselect trap suitable for actual flow
	Air binding has occurred	Perform a bypass blowdown or consider switching to a product with a built-in air vent or air vent valve
	The trap operating pressure exceeds the maximum specified pressure, or there is insufficient pressure differential	Compare specifications and actual operating conditions
