In addition liquid oxygen (LOX) valves are “black light” tested to check for any hydrocarbons

 • Valves do not require a minimum operating pressure • Valve are provided with stainless steel seats 

• The solenoid valves satisfy all relevant EC directives

GENERAL Differential pressure See «SPECIFICATIONS»  [1 bar =100  kPa] Maximum viscosity 65 cSt (mm2/s) 

Response time 5 - 25 ms fl uids (✴) temperature range (TS) seal materials (✴) cryogenic fl 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 verifi 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

FEATURES • The solenoid valves will withstand the severe service encountered in controlling cryogenic 

fl uids, such as liquid oxygen (-183°C), liquid argon (-186°C) and liquid nitrogen (-196°C) 

• All valves are degreased, cleaned, tested and packed to keep them free from moisture.
