The A.R.I. R-30 Series is line of metal, diaphragm-operated hydraulic control valves. The valves are suitable for installation in agriculture, water transmission and waterworks systems for irrigation, landscape and infrastructure applications. The R-30 series has an innovative elliptic shaped diaphragm that integrates well with a wide variety of regulating control pilots, solenoids and control accessories. They are compatibility designed for water level control, flow control, electric & remote control as well as pressure reducing & pressure sustaining operation.Excellent regulating capabilities for a wide range of flow rates from drip (500 l/h) up to maximum flowOperational from low pressure up to 16 barHighly reliable operation and durable over timeQuick-reaction operationRapid response to changes in flow rateDesigned to reduce cavitation damageSilent operationLow head lossesWide range of connections: Flanged, Threaded and GroovedSimple mechanismEasy inline maintenanceUser-friendly
Pressure Reducing Valve
Maintains a constant downstream pressure regardless of upstream pressure or flow rate fluctuations. The set point of reduced pressure is adjustable by a 2-way or 3-way pilot valve. A spring-loaded diaphragm inside the pilot reacts according to the downstream pressure changes. The pressure fluctuations are compensated by gradual opening and closing of the valve.
Pressure Sustaining/ Relief Valve
The pressure sustaining component maintains the minimum preset upstream pressure regardless of changes in the downstream pressure or in the flow rate. The pressure relief is a sustaining valve that releases excess flow from the system.
Electric Control Valve
The electric valves are used for remote commands by solenoids in a normally opened or closed position and can operate in combination with all the hydraulic pilot applications.
Level Control Valve
The level control valves are used for a wide range of applications with a horizontal float valve, a vertical (differential) float valve with one or two setting levels or with an altitude P-36AL hydraulic pilot with adjustable settings, as well as with electric level sensors to match all different water reservoir needs.
