Control Valves: 800 Series Valves 1000 Series Valves Air Control Valves

Premium Performance Not all valves are created equal. As a hydraulically operated sleeve-type valve, Nelson control valves are designed for reliable and efficient operation. the smooth open/close, to the ultra-accurate pressure control pilot and high flow capacity. Every Nelson valve is custom built and is functionally tested before it goes out the door. There simply isn’t any other valve with better hydraulic performance – from

CONTROL VALVE FAMILY HYDRAULIC STABILITY Nelson’s complete line of control valves maintain optimum hydraulic performance in agricultural and industrial applications where reliability is key. Solutions include zone control, pressure control, flow control, and air control. Aluminum / Cast Iron Glass-filled Nylon Continuous Air & Vacuum Relief

800 Series valves at pump station headworks. Washington, USA.

Solutions PIVOT POINT Automate center pivots with pressure and/or flow control valves to prevent water hammer and pressure fluctuations. PRESSURE RELIEF Protect the system with a pressure sustaining/relief valve that automatically opens when a pressure spike occurs. END GUN Reliable primary or secondary end gun control valves. PUMP Maintain hydraulic stability with continuous acting air vents and a pressure sustaining and/or reducing valve.

BIG GUN ® Control valves and TWIG® Wireless Controls make an automated solid set Big Gun® sprinkler system possible. Precision irrigation requires continuous acting air vents and TWIG® wireless automated hydraulic valves. Get the air out with the ACV200, and use a pressure sustaining-normally open (PSNO) valve to provide optimum backflush pressure. DRIP / LAYFLAT ZONE CONTROL FILTER STATION Accurate and stable pressure reducing valves maintain a truly constant pressure at each block for total farm uniformity.
