Can the Galvanized Steel Manometer Shut-Off Valve with Male Thread, Type FT 290 / FT 291 withstand continuous operation at 350 bar and temperatures between -20°C and +100°C?

Yes. The Galvanized Steel Manometer Shut-Off Valve with Male Thread, Type FT 290 / FT 291 is rated for continuous operation up to 350 bar and within the temperature range of -20°C to +100°C. It is constructed from galvanized carbon steel with a carbon steel needle, NBR/PTFE seals, and a polyamide 66 knob, providing reliable sealing and durability for prolonged use at those pressures and temperatures. For applications needing greater corrosion resistance, an AISI 316 stainless steel version is available on request.

Is the Galvanized Steel Manometer Shut-Off Valve with Male Thread, Type FT 290 / FT 291 available in AISI 316 stainless steel for increased corrosion resistance?

Yes. The Galvanized Steel Manometer Shut-Off Valve with Male Thread, Type FT 290 / FT 291 is available in AISI 316 stainless steel upon request for increased corrosion resistance. This option provides enhanced durability in aggressive or corrosive environments while retaining the valve’s features: manometer isolation, panel mounting via the thread under the knob, carbon steel needle (or stainless option as requested), NBR/PTFE sealing, 350 bar working pressure, and −20°C to +100°C operating temperature.
