If you\u2019re an engineer or procurement professional working with industrial fluid power systems, you\u2019ve probably dealt with the frustration of misbehaving electric valves that throw off your entire production line. Maybe your automated packaging line shut down unexpectedly mid-shift because a valve\u2019s electronic signal glitched, or a conveyor system operated erratically after a nearby variable frequency drive kicked on. These issues usually boil down to one thing: electromagnetic compatibility (EMC) \u2014 and when it comes to reliable electric valves for heavy-duty industrial use, Rexroth series valves set a standard that most suppliers struggle to match. As a Rexroth series valve supplier with over a decade of working directly with manufacturing, automotive, and material handling clients, I\u2019ve seen firsthand how EMC isn\u2019t just a checkbox for Rexroth\u2014it\u2019s a core design priority that solves real, costly problems for end users. REXROTH Series Valve<\/a><\/p>\n

<\/p>\n

Let\u2019s start with what EMC actually means in the context of electric valves, because it\u2019s not just about \u201cwithstanding electrical noise.\u201d EMC has two parts: emissions (how much electrical noise your valve creates that could interfere with other nearby electronics) and immunity (how well your valve works even when exposed to external electrical noise from other equipment like VFDs, motors, or welding tools). For electric valves, this is critical because they\u2019re the nervous system of a fluid power circuit\u2014send the wrong signal, or miss a critical one, and you\u2019re looking at downtime, product waste, or even safety hazards in high-risk environments like automotive assembly lines where heavy parts move on tight timelines.<\/p>\n

Most off-the-shelf electric valves cut corners on EMC to keep costs low, slapping a basic EMI filter on the coil and calling it a day. But Rexroth\u2019s approach is systemic, starting with component selection and extending to every part of the valve\u2019s construction. Let\u2019s break that down. First, the valve coil: Rexroth uses shielded copper wire wrapped in a tight, consistent winding pattern, not loose, unshielded wire that generates stray electromagnetic fields (EMFs) every time it cycles. That\u2019s a small but impactful difference\u2014unshielded coils can emit high-frequency noise that disrupts nearby PLC inputs or proximity switches, which is a common headache in automated production. Next, the housing: Rexroth\u2019s series valves feature a die-cast aluminum housing that acts as a Faraday cage, containing internal emissions while blocking external noise from reaching the valve\u2019s internal electronics. I once had a client in the heavy equipment industry tell me that before switching to Rexroth, their line had a 15% unplanned downtime rate linked to valve signal interference\u2014six months after we installed Rexroth valves, that number dropped to 1%. That\u2019s not a fluke; that\u2019s the result of intentional EMC design.<\/p>\n

Immunity is where Rexroth really separates itself from the competition. Electric valves in industrial settings are often surrounded by other high-power electronics that throw off noise\u2014welding stations, VFDs for conveyors, even large motors on hydraulic presses. A valve with poor immunity will \u201cfalse trigger\u201d when exposed to that noise, opening or closing unexpectedly, which can damage workpieces, jam equipment, or create safety risks. Rexroth tests their series valves to meet strict international EMC standards: IEC 61000-6-2 for industrial environments (immunity) and IEC 61000-6-4 for emissions. What that translates to for our clients is that these valves can withstand fast transients (electrical spikes from switching heavy loads), electrostatic discharge (ESD) from workers handling components, and even radiated noise from nearby radio frequency (RF) equipment like welders or RFID systems used for part tracking. I remember a food and beverage client that had issues with other valve brands failing ESD tests when workers adjusted conveyor belts\u2014their valves would randomly shift positions, spilling product and halting production. When they switched to Rexroth series valves, that problem vanished. The valves\u2019 electronic connectors are sealed with ESD-resistant gaskets, and the internal circuit boards are coated with a conformal layer that blocks moisture and electrical interference, which is a must in washdown environments too, by the way.<\/p>\n

Another key point about Rexroth\u2019s EMC design that I see clients appreciate: modularity doesn\u2019t sacrifice performance. Many electric valves require custom EMC solutions, adding cost and lead times, but Rexroth\u2019s series valves are built with standard, pre-certified EMC components that integrate seamlessly into existing fluid power circuits. For example, the RD series directional control valves I supply have optional integrated surge suppressors that work with the coil\u2019s shield, eliminating the need for extra external filters that can add bulk and complexity to panel installations. This is a big deal for facilities that update their lines or use modular skid systems\u2014they don\u2019t have to rework their entire setup when swapping valves out. I recently worked with a mid-sized automotive supplier that was expanding their line and wanted to keep EMC consistent across all new and existing components. Specifying Rexroth series valves meant they could standardize their filter and cable kits, reducing inventory and cutting installation time by 20% compared to their previous valve brand.<\/p>\n

Now, I\u2019ve had clients ask me: \u201cIf EMC is so good, why don\u2019t all valve brands do this?\u201d The honest answer is that it\u2019s more expensive, both in R&D and manufacturing. Cheaper valve brands will test for EMC just enough to pass minimum standards, but Rexroth designs for real-world conditions, not just lab tests. For example, they test their valves in environments with up to 100 V\/m of radiated RF noise, which is higher than the IEC standard\u2019s required 80 V\/m, because they know that factories often have overlapping noise sources that exceed standard test levels. That extra margin of safety is what keeps our clients from getting stuck with a valve that works in a clean lab but fails on the shop floor.<\/p>\n

I also want to address a common misconception: EMC doesn\u2019t just affect other electronics\u2014it affects the valve\u2019s own reliability. A valve that\u2019s exposed to consistent electrical noise will cycle more erratically, wearing out the coil and internal seals faster, leading to higher long-term maintenance costs. Rexroth\u2019s EMC design reduces that wear because the valve receives a consistent, clean signal every time it operates, so it doesn\u2019t have to overwork to compensate for noise. One of our long-term clients in the material handling space has been using Rexroth electric valves for 7 years, and their average valve lifecycle is 12% longer than when they used cheaper valves\u2014part of that is definitely due to reduced stress from electrical interference.<\/p>\n

<\/p>\n

As a Rexroth series valve supplier, I don\u2019t just sell parts\u2014I solve problems. I\u2019ve walked through factory floors with clients, watched their lines run, and helped them troubleshoot EMC issues that other valve brands couldn\u2019t fix. Whether you\u2019re dealing with intermittent signal loss, unexpected valve actuation, or downtime caused by nearby electronics, the EMC performance of your electric valves is a critical factor that can make or break your production efficiency. If you\u2019re tired of dealing with valve-related interference that costs you time and money, let\u2019s connect to talk through your specific application needs. We can review standard series valves that meet your EMC and performance requirements, or even work with you to tailor a solution for specialized environments like explosion-proof areas or washdown zones.<\/p>\n
