10 Dismounting and removal
Risk of injury due to dismounting whilst pressurised or with live parts!
Dismounting whilst pressurised or with electrical power switched on can result in
injuries due to sudden pressure build-up or electric shock.
f De-energise and de-pressurise the relevant system parts before dismounting
the valves.
f Lock out the system to prevent it being switched back on again.
11 Technical data
11. 1
General data
Design: 2/2-way, 3/2-way and 4/2-way poppet valve design with plastic piston
(series 27) and metal piston (series 21)
Actuation: Pneumatically actuated or solenoid-actuated
Medium: Compressed air (neutral gases), filtered per ISO 8573-1 (class 7/40 —m,
recommended class 6/5 —m), oiled or unoiled (mineral oils per DIN 51519/ISO-VG,
viscosity class 32)
Pressure range: 1 to 16 bar (depending on design), control pressure • operating
pressure
Temperature range
• Pneumatically-actuated valves:
Ambient temperature
min.
- Series 27
4 °C
- Series 21, type H
-17 °C
- Series 21, type O
-40 °C
• Electromagnetically-actuated valves:
