Solenoid Valves Better Not Lose Your Cool
Bürkert presents a valve technology for high and extremly low temperatures with its new type 2610 solenoid valve. Its core is a metal bellows of durable stainless steel, which thermally decouples the coil from the valve body.
This design prevents both condensation and overheating. The broad temperature spectrum from -200° C to +180° C makes this valve ideal for use in extreme temperatures, such as in cryogenic applications. In addition, the welded metal bellows system provides high gas tightness. Another standard feature of the type 2610 valve is the power-reducing “Kick & Drop” electronics. The high starting power of 72 W required for opening of the valve is generated by overexcitation of the coil. Immediately (400 ms) after the valve has switched, the power consumption is electronically reduced to the substantially lower holding power of 4 W.
Another ideal use for the solenoid valve is in critical chemical applications. The metal bellows system, consisting of durable stainless steel and a PTFE seal, makes the type 2610 suitable for safe switching of mild acidic and alkaline solutions. In addition, the fully welded metal bellows system enables optimal leakage rates up to 10-6 mbarl/s.
