Response time 5 - 25 ms ? uids (?) temperature range (TS) seal materials (?) cryogenic ? uids - 196°C to + 90°C PTFE

MATERIALS IN CONTACT WITH FLUID (?)  Ensure that the compatibility of the

uids in contact with the materials is veri? ed Body Brass Core tube Stainless steel Core and plugnut 

or with cable length of 2 m  (see Solenoids, Coils & Accessories section)

INSTALLATION ? The solenoid valves can be mounted in any position without affecting operation 

? Solenoid valves have 2 mounting holes in body 

? Threaded pipe connections are: B = NPT (ANSI 1.20.3); E = Rp (ISO 7/1) 

? Installation/maintenance instructions are included with each valve
