EHCOTECH  B21V-1/2-CC-120VAC SOLENOID VALVE

This is a great general purpose valve for many water, air, fuel, or gas projects.

General

• 1/2" NPT Ports (0.840" outer thread diameter); NPT is the U.S. standard pipe thread
  
• 120-Volt AC
  
• 2-way, Normally Closed (energize to open, de-energize to close)
• FKM (Viton) diaphragm
  
• Semi-Direct Acting Valve (allows for good low pressure performance)
• Large internal orifice (5/8" or 16 mm internal orifice diameter)
• Cv value:  4.8

Pressure and Temperature

• 0 to 145 psi or vacuum
• Max media temp: 265° F (130° C)
• Zero differential pressure valve
  
• Gravity feed capable (For best gravity feed performance we recommend EHCOTECH motorized valves)
  

Suitable Media

• Water, Air, Various Gases
  
• Diesel Fuel, Gasoline, Glycol
  
• Other media compatible with FKM (Viton)
• NOTE: do not use general purpose valves for Natural Gas. Natural Gas valves are optimized for 0 to 0.5 psi range.

Electrical

• 110/115/120-volt AC / 22VA (Volt-amps) or 22 Watts
  
• Coil tempreature will stabilize between 155° and 185° F during long activation periods (typical for general purpose solenoid valves)
  
• Contact us regarding applications requiring a very large number of cumulative activation hours
