SL-40 Series, Safety Relief Valve, Fukutaro

SL-40 Series, Safety Relief Valve, Fukutaro

Used in stainless steel lines for pressure vessels, hot water boilers, heat exchangers, the secondary sides of reducing valves, etc.

[Features]
• The "Fukutaro" safety relief valve falls midway between safety valves used mainly for steam and gases, and relief valves used mainly for liquids.
• Simple structure and excellent corrosion resistance suitable for a wide variety of applications such as pressure containers, safety systems for various types of equipment, hot water boilers, hot water supply, air conditioning and heating equipment, and safety devices with pressure-reducing valves.
• Sealed-type safety relief valve with high corrosion resistance in the spring case, main section SCS, and spring SUS.
• Can be used for three different fluid types:, steam, gases, and liquids (metal seated type).
