LEMA 170S Series Inline Globe Valves

LEMA 170S Series Inline Globe Valves

DIG’s LEMA 170S-XXX Series Inline Globe Valves, available in 3/4″ to 2″ sizes, are designed for seamless integration with LEIT 4000, X, and XRC solar-powered control systems. These heavy-duty valves, equipped with LEMA solenoid actuators, offer extended operating distances up to 7,500 feet using 12-gauge wire. Constructed from weather-resistant, high-impact, glass-reinforced nylon with a stainless-steel spring, The LEMA valve series provides exceptional hydraulic performance with balanced opening and closing at operating pressures up to 150 PSI.

Key Features:

  • Durable Construction: Made from glass-reinforced nylon with a stainless steel spring, ensuring long-lasting durability and resistance to harsh environmental conditions.
  • Superior Hydraulic Performance: Delivers high flow rates with minimal pressure loss, ideal for various irrigation applications.
  • Reliable Operation: The valves are normally closed, with a smooth opening and closing mechanism that prevents pressure surge hazards.
  • Easy Maintenance: Designed for simple inline maintenance, minimizing downtime and servicing efforts.
  • Rugged Diaphragm: Reinforced, self-cleaning diaphragm ensures reliable operation even in conditions with dirty water.
  • Flow Control: Equipped with a flow control handle for precise water flow adjustment and manual shutoff.
  • Manual Operation: Features a manual internal bleed via the LEMA solenoid actuators, allowing the valve to be opened without external water spillage.
