P6 Pro Servo Proportional Valve FAQs
Hydraulic Servo Proportional Valve – P6 Pro
The P6 Pro is a robust hydraulic servo proportional valve designed for NG06 (CETOP 3) ports. Its performance includes a flow range of 2.6-10.6 gpm (5-40 lpm), frequency over 100 Hz, and a fast response time of <10 ms. This model offers a cost-effective alternative to the S6 Pro and is made for applications with more flexible response times. It offers affordable pricing for industrial quantities in metal processing, ceramics, injection molding, wood and timber, and more.
It is designed for smaller and mid-sized industrial systems. Its fast response and fine resolution make it well suited to machinery that depends on accurate motion management in a smaller footprint. It installs easily into existing NG06 platforms and brings dependable day to day performance with minimal setup.
Servo Proportional Valves Designed for Industrial Applications
The P Series is designed for industrial and automation applications, such as injection molding equipment, ceramic presses, energy systems, and automated production lines. See how it compares to Domin’s original S Series in industrial applications:

If you need faster response rates (<3.5 ms compared to P6 Pro’s <10 ms), view the S Series counterpart, the S6 Pro, our most popular model. The S6 Pro also offers a slightly higher flow maximum (15.9 gpm / 60 lpm compared to P6 Pro’s 10.6 gpm / 40 lpm). If you are looking for even higher capabilities, the P10 Pro offers a maximum flow rate of 42 gpm (160 lpm).
