2/2 CLOSED WHEN DE-ENERGISED (NC) DIRECT ACTING When the coil is energised the valve opens. The valve does not require minimum operating pressure differential. Maximum operating pressure depends on the orifice diameter and coil power. Due to the coil power limitations high flow rates cannot be achieved. 3/2 CLOSED WHEN DE-ENERGIZED (NC) DIRECT ACTING Valve function similar to 2/2 NC, only with 3 ports that allow 2 ways simultaneously: one open and the other closed. 3/2 valves are often used as cylinder activators. The same valve also allows NO function when properly connected. 2/2 CLOSED...

ENGINEERING INFORMATION ENGINEERING MATERIALS The choice of materials used depends on the type of fluid to be controlled. Bodies are made of machined brass, bronze, thermoplasts, stainless steel or nickelized brass or bronze. Seals - diaphragms are chosen according to mechanical, thermal and chemical requirements. NBR is the standard material for use with neutral chemically fluids at temperatures up to 90°C. At higher temperatures, EPDM, FPM and PTFE can be used. In some cases (high temperature and high cycling rate) stainless steel can also be used. Characteristics of sealing materials NBR...

Electrical protection - IP rating Apart from standard coils, original explosion- and waterproof coils are also available, thus allowing the use of solenoid valves in practically any environment. Standard coils are encapsulated in special thermoplastic resin which prevents the intrusion of damp and protects the winding from mechanical damage. Explosionproof coils are encapsulated in epoxy resin. Basic IP rating for a coil is IP00, whereas IP65 can be achieved with properly fitted plug (to DIN 43650). The TM35k type coil with IP67 rating is designed for extremely damp ambients (also water...
