SL-44 Series Safety Relief Valve

SL-44 Series Safety Relief Valve

For use in pressure vessels, hot water boilers, heat exchangers, and secondary reducing valves.

[Features]
- Installed between safety valves used mainly for steam and gas, as well as relief valves used mainly for liquids.
- Lighter weight and a lower height than conventional cast-iron parts.
- The main body, except for the spring case, is made of stainless steel with superior corrosion resistance.
- Can be used the same way as the Fukutaro part series. (Main body parts are shared with the SL-37/38 line and feature identical performance, except for the spring case and valve seat)
