P12 Pro Servo Proportional Valve FAQs

The P12 Pro has a flow rate of 42 to 153 gpm (160 to 580 lpm) and response rate of <12 ms, the same flow capabilities of its S Series counterpart: the S12. The P12, however, features a lower response rate (S12: <6.5 ms) for applications where response time is not critical, but high flow is still necessary.

	Flow Rate	Response Rate
P6 Pro	2.6 to 10.6 gpm (5 to 40 lpm)	<10 ms
P10 Pro	10.6 to 42 gpm (40 to 160 lpm)	<20 ms
P12 Pro	42 to 153 gpm (160 to 580 lpm)	<12 ms

Compare Domin P Servo Proportional Valves

Presses systems, power generation, industrial automation, wood & timber, metal processing, and marine.

The P12 Pro is designed for heavy duty applications with high flow rates (up to 153 gpm). It is specifically effective for applications with high loads and large-scale industrial environments including press systems, metalworking equipment, wood-processing machinery, and more.

Yes. The P12 Pro features a standard NG16 port pattern.

The P12 Pro is compatible with the NG16 mounting pattern/interface, also known as NG16 (CETOP 7), and ISO 4401-07-07.

Hydraulic Servo Proportional Valves – P12 Pro

Compact Power. Proven Reliability.

The P12 Pro is a two-stage hydraulic servo proportional valve designed for NG16 ports (CETOP 7). Its performance includes a flow range of 42-153 gpm (160-580 lpm), frequency over 60 Hz, and a response time of <12 ms. It is used for pressing applications and processing lines for ceramics and metal manufacturing.

It delivers the required performance without the complexity of traditional servo valves, prioritising compact size, low mass, and robustness for continuous operation. Compatibility with standard NG16 interfaces enables easier commissioning, stable long-term behavior, and reduced maintenance in production systems.

For better performance (<6.5 ms response rate and >100 Hz frequency response) with the same maximum flow rate, view the S12 Pro. If you don’t need performance that is quite as dynamic (<20 ms response rate) with lower flow capabilities (42 gpm max), view the P10 Pro.
