The TLV BE8H-16 is a bellows sealed globe valve with a flanged connection, designed for industrial systems handling steam, water, and other non-hazardous fluids. Its durable stem is protected by both a bellows seal and a secondary gland, ensuring exceptional leak-tightness and safety under demanding conditions.

The non-rotating stem and non-rising handwheel with position indication increase the valve's lifespan and make operation straightforward. Built with a stainless steel plug and seat ring, the BE8H series delivers reliable fluid shut-off across various piping systems.

Features

• Two-port durable bellows sealed shut-off globe valve for steam, water and other fluids.
• Durable stem with bellows seal and gland.
• Non-rotating stem and non-rising handwheel with position indication.
• Plug and seat ring made of stainless steel.
• Free of asbestos, PCB and CFC.

WARNING

Do not use for toxic, flammable or otherwise hazardous fluids.

Configuration

The valve consists of a body, seat ring, bonnet, stem, handwheel, gland, plug, and a flexible bellows.

Installation

TIP

The valve can be installed in any position, however it is recommended to install it with the handwheel upwards.

• Steam pipelines should be fitted in such a way as to avoid condensate collection; in order to avoid water hammer, a steam trap should be installed.
• Take note of the medium flow direction, marked with an arrow on the body. Flow direction is established by the following rules:
  • PN16 – PN25 (BE8H-16 / BE8H-25): Under the disc for DN15 – DN150. On the disc for DN200.
  • PN40 (BE8H-40): Under the disc for DN15 – DN100. On the disc for DN125 – DN150.
• A strainer (wire mesh filter) installed before the valve increases the certainty of correct operation.

Troubleshooting

Fault	Possible Reason	Remedy
No flow	Valve closed	Open the valve
	Flange dust caps were not removed	Remove dust caps on the flanges
Poor flow	Valve is not open enough	Open the valve
	Dirty filter / Clogged pipeline	Clean or replace the screen / Check the pipeline
Difficulty operating the handwheel	Dry stem / Gland overtightened	Grease the stem / Slightly slacken gland nut
Stem leakage	Bellows damage	Tighten the gland until leakage stops and replace the upper part of the valve
Seat leakage	Incorrect shut off	Tighten the handwheel without using any auxiliary tools
	Seat or disc damage	Replace the valve and contact the supplier
