LOW WATT VALVES
Series L58 >> Model L581
Very Low Watt — 2-Way Normally Open Valve
Easily interfaced with circuit boards and miniaturized components.
The versatility is for connecting electronic signals to pneumatic outputs. The small size is ideal for stand alone (with #10-32 UNF-2B ports) or multiple valves mounted on one manifold. Air and other common gases — filtration recommended — 30 microns or less.
• May be used to “pilot” larger valves.
• Ideal for micro electronic production equipment.
• Great for medical and chemical analytical applications.
• Can operate directly from most programmable controllers. • High quality engineering.
Note: This valve also available as an operator. Refer to following page.
