SL-43 Series, Safety Relief Valve

SL-43 Series, Safety Relief Valve

Used for pressure vessels, reducing valve secondary sides, etc.

[Features]
· The safety relief valve falls midway between safety valves used mainly for steam and gas, and relief valves used mainly for liquids.
· Lighter weight due to lower height than conventional cast iron products. Stainless steel is used for all components other than the main body and spring case, providing superior corrosion resistance (compared to other comparable products manufactured by our company).
· Achieves a 22 to 36% weight reduction compared to conventional parts.
· Can be used in the same manner as the Fukutaro series (parts other than the main body, spring case and valve seat are common with, the SL-37/38 model and so offer the same performance).
