Original Press Release:



Improved Fusible Link Assembly Available for 3000 Series



Cincinnati, OH USA - Marwin Valve introduces an improved, heavy duty fusible link assembly for the 3000 Series.

The 3000 Series Fusible Link Assembly now features an improved, space saving design, utilizing a cam placed on top of the spring pack rather than a fixed loaded arm. This design can be used as a standard manually operated valve as well as a spring loaded fusible link actuated valve, potentially eliminating extra valves.

Fusible link valves spring closed or open when high temperature heat from a fire causes a fusible link to break. The most common application is to fail close to shut off the flow of flammable liquids or gases during a fire. They are also used as fail open valves to allow the flow of water, or fire extinguishing chemical in fire suppres-sion systems.

The "Low Torque" series fusible link assembly (0 to 150 in-lbs) uses the valve handle to arm the fusible link to assembly. The valve handle can then be used for manual operation once the fusible link assembly in armed.

The "Mid Torque" series fusible link assembly (160 to 830 in-lbs) uses a detachable arming handle to arm the fusible link assembly, while the original valve handle can be used for manual operation when the fusible link assembly is armed.

The "High Torque" series fusible link assembly (835 to 21000 in-lbs) uses a declutchable manual override gear operator to arm the assembly, and can also be used to operate the valve when the fusible link assembly is disarmed.
