Made in Japan
Manufacturer: Chiyoda Seiki
Model: LH-15

Feature

Material: The main body is made of brass.
Pressure-sensing shutoff mechanism: Shuts off the gas flow path in the event of backfire. The pressure sensing shutoff mechanism also maintains the shutoff.
Heat-sensing shutoff mechanism: When gas continues to burn inside the safety device, the heat-sensing shutoff mechanism shuts off the gas supply.
Pressure sensing type = The shutoff is restored by turning the restoration pin one turn from the outside. Heat-sensing type = We will repair it for a fee.

Outline

This is a dry-type safety device for piping dedicated to hydrogen that can be used in hydrogen gas supply facilities in the melting and processing industry, glass and ceramic industries, metal reduction and metallurgy, petrochemical industry, and other industries that use hydrogen gas. It reacts to reverse gas supply and prevents the propagation of reverse fire.
