2' to 3' Brass Big Valves — DN50 / DN65 / DN80 Normally Closed Water Solenoid Valve Model / Coil option: COILS24VAC_NBR80CELSIUS (selectable; shown for DN80) Voltages available: AC 220V, AC 380V, DC 12V, DC 24V Why this valve solves your problem Reliable on/off control for mediumtolarge water lines: the normally closed brass solenoid valve stays closed without power and opens when energized, giving simple, failsafe control for water systems. Flexible voltage and size options let you match the valve to existing electrical and piping systems without complex modification. Solid brass construction offers durability for longterm use in typical water service environments. Key features and attributes Sizes: 2' (DN50), 2.5' (DN65), 3' (DN80) — choose the DN size that matches your piping. Material: Brass body and valve components suitable for water applications. Function: Normally closed solenoid valve — remains closed on loss of power. Voltage options: AC 220V, AC 380V, DC 12V, DC 24V to suit different control systems. Coil selection: Twocoil option available; coil model COILS24VAC_NBR80CELSIUS is provided as a selectable coil (model name includes '80CELSIUS'). Media: Designed for water flow control. Application fit: Intended for largerdiameter water lines (DN50–DN80). Benefits at a glance Simple replacement or upgrade for existing DN50–DN80 water lines with minimal piping changes. Multiple voltage choices reduce the need for stepdown transformers or additional power supplies. Brass construction balances strength and corrosion resistance for dependable service life. Normally closed configuration provides safe default position in powerfail conditions. Typical use cases Agricultural irrigation and largescale sprinkler systems: control main feed lines or zone isolation valves where reliable on/off operation is required. Industrial water distribution and process plants: manage supply lines, washdown systems, or make/bypass circuits in manufacturing and processing facilities. HVAC and building services: control chilled water, condenser water, or makeup water lines in commercial systems that require largerdiameter valves. Ordering and selection notes Select the correct DN size (DN50 / DN65 / DN80) to match your pipework (2'–3'). Choose the required coil/voltage (AC 220V, AC 380V, DC 12V, DC 24V) when ordering; COILS24VAC_NBR80CELSIUS is available as a selectable coil option (referenced for DN80). Confirm electrical compatibility and mounting requirements with your control system prior to installation. Compatibility and installation guidance Designed for water service; ensure system cleanliness and appropriate filtration to avoid debrisrelated valve wear. Intended for integration into systems already using DN50–DN80 piping; verify flange or thread compatibility with your fittings. This brass normally closed solenoid valve provides a robust, straightforward solution for controlling larger water lines with flexible voltage and coil options. Select the correct size and coil/voltage to match your system for reliable operation.
