Domin Launches High-Flow Valves for Use in High-Power Hydraulic Systems
To help meet the performance needs of high-power hydraulic systems, Domin is introducing the S12 Pro and P12 Pro hydraulic valves. They feature a two-stage valve architecture built on the company’s existing valve technology.
The valves are suited for high flow applications up to 580 l/min (153 gpm) in which control stability and reliability directly impact performance and uptime. Such applications include large presses, turbines, industrial test rigs, large-scale automation and others that typically use hydraulic valves matching the NG16 (CETOP 07) mounting size.
Each valve is designed to address different performance requirements in these types of applications.
“The S12 Pro is suited to performance-critical applications requiring fast response, precision, and stable behavior under demanding conditions, while the P12 Pro is designed for industrial environments where repeatability, straightforward integration, and predictable lifecycle cost are the priority. Together, they cover both ends of the NG16 requirement spectrum,” Jerome Carson, Valve Product Owner at Domin, explained to Power & Motion.
The S12 Pro is a high-performance servo valve designed to provide fast response, stable control under heavy load, and consistent behavior at high flow and pressure which makes it well suited for applications requiring a high level of control quality and speed. These include test rigs, large presses, turbines, injection molding, metal processing and motion platforms.
Features of the S12 Pro Hydraulic Valve include:
- Response time of <6.5 ms
- Rated flow of 250-580 l/min (66-153 gpm)
- Hysteresis of <0.2%
- Frequency Response of >100 Hz
- Protection rating of IP65
- Onboard electronics with spool position feedback
- Temperature range of -20 to 60 C (-4 to 140 F)
Ease of integration and reliability are more the focus for the P12 Pro servo proportional valve. It combines predictable servo proportional behavior with strong dynamic response, making it well-suited to processing lines and large-scale automation where stable, consistent control under high duty conditions is the priority.
Features of the P12 Pro Hydraulic Valve include:
- Response time of <12 ms
- Rated flow of 160-580 l/min (42-153 gpm)
- Hysteresis of <0.2%
- Frequency Response of >60 Hz
- Protection rating of IP65
- Onboard electronics with spool position feedback
- Temperature range of -20 to 60 C (-4 to 140 F)
S12 Pro and P12 Pro Hydraulic Valves Aim to Meet Multiple Industry Needs
Carson told Power & Motion that development of these valves was driven by a gap Domin saw in the market. Customers usually have to decide whether to prioritize performance traits, reliability or cost because improvements in one area typically come at the expense of another.
But the S12 Pro and P12 Pro hydraulic valves aim to minimize those compromises by “delivering high-performance, stable control where it matters most, alongside efficient, reliable operation in industrial environments,” he said. “Both products are engineered to maximize return on investment by combining performance, efficiency, and lifecycle value without forcing customers to choose between them.
“Across the industry, there is increasing pressure to maximize uptime, reduce maintenance disruption, and extract more value from installed equipment. At the same time, engineers are prioritizing more efficient, compact, and cost-effective system design. The S12 Pro and P12 Pro align with these trends by delivering stable control, reduced maintenance burden, and predictable long-term performance, helping customers improve operational efficiency without adding unnecessary complexity,” he concluded.
