305DC 3/4" & 1" 6-12 VDC In-Line Valves

The S-305DC-075 and 100 plastic inline (globe pattern) valves, with a 6-12 VDC, two-way magnetic latching solenoid are suitable for residential, commercial and agricultural irrigation systems. The 3/4" and 1" support excellent hydraulic performance and long life operation. The S-305DC series operate with DIG battery operated controllers and LEIT 2 ET solar powered controller. The S-305DC-XXX DC globe valves use available with encapsulated, watertight, two-way magnetic latching solenoid that requires minimal power to operate. The S-305DC-XXX series are constructed of weather-resistant, glass-reinforced nylon and a stainless steel spring to provide balanced opening and closing at a pressure rated up to 150 PSI.

Features

  • Constructed of glass-reinforced nylon with a stainless steel spring; non-corrosive materials
  • High flow rate with low pressure loss
  • compact design with minimal space
  • simple design structure for easy maintenance
  • Bonnet secured with 6 SS screws for easy service
  • Normally closed
  • Easy inline maintenance
  • Use encapsulated, watertight, two-way, 6 to 12 VDC magnetic latching solenoid
  • Smooth valve opening and closing prevents pressure surge hazards
  • Rugged, reinforced self-cleaning diaphragm provides reliable operation even with contaminated water
  • Balanced diaphragm supported by SS spring allows for low opening pressure and secured closing
  • Self cleaning diaphragm for reliable operation
  • Flow control handle for water flow adjustment and drip-tight manual shutoff
  • Manual internal bleed override via the solenoid
