Water Valves – How to Choose the Right Valve for Your Installation

Solenoid valves – automatic flow control

Electromagnetic (solenoid) valves enable remote control of water flow via electrical signal. Models like the Elektromagnetni ventil 3" RN 180 UN-24 VAC RAIN operate on 24V AC power ensuring safe use in irrigation systems and automated installations. Valve diameter (1", 2", 3") should match your system's flow requirements – larger diameters allow higher flow rates but require stronger electrical signals.

AC or DC power supply – which option is better

AC-powered valves like 24VAC models are the standard choice for stationary systems with mains electricity access. DC versions (12V or 24V) are ideal for solar installations and mobile systems without grid power. AC valves are generally more durable for continuous operation, while DC models consume less energy in standby mode.

Connection diameters and flow rate

The connection diameter directly determines maximum flow through the valve. A 3" valve such as the Elektromagnetni ventil 3" RN 180 UN-24 VAC RAIN supports flow up to 180 l/min, making it ideal for professional irrigation or industrial installations. For residential applications, 1" or 1.5" valves with flow up to 60 l/min are typically sufficient.

Operating pressure and temperature range

Check your system's operating pressure before purchasing – most valves work within 0.5-10 bar, but some models require minimum 1 bar pressure for reliable operation. Temperature range is equally important: standard valves handle +1°C to +60°C, while specialized models exist for hot water up to +90°C or freeze-resistant applications.

Application in irrigation systems

Brands like RAIN and Srbija offer valves designed specifically for automated irrigation of gardens, sports fields, and agricultural areas. Solenoid valves connect to programmable controllers that enable precise zone-based watering schedules. For reliable long-term use, choose valves with inlet filters that prevent mechanism clogging.

Installation and maintenance

Valves can be mounted horizontally or vertically, but always check the arrow on the housing indicating flow direction. Regular filter cleaning and gasket inspection extends valve lifespan. During winter periods, always drain valves in non-frost-protected systems to prevent housing damage from freezing.
