Upgrade Your Parker or Bosch Rexroth Valve to a Domin Servo Valve

Replacing a Parker or Bosch Rexroth servo valve on an injection molding press is an opportunity to improve response, reliability, and operating efficiency in an easy plug-and-play upgrade. Domin servo valves function as drop-in upgrade options for existing Parker or Bosch Rexroth valves, offering higher performance, lower energy loss, and reliable control without a full system redesign.

Replacing a servo valve can be as easy as finding a drop-in replacement with the same conventional mounting style that fits into the system’s intended specifications. However, when your servo valve has failed or is not performing adequately, there is an opportunity to upgrade, and, in turn, your improve overall system health and performance. This can translate to better response times, lower cost of ownership, and more.

Domin valves are designed as direct drop-in replacements for competitor brands such as Parker or Bosch Rexroth due to their standard port patterns and straightforward integration process. Learn more about Domin valves vs traditional legacy style valve designs.

Through local inventory and Domin’s lead time zero initiative, Parker or Bosch Rexroth valves can be replaced in days. If you have a Parker or Bosch Rexroth model below, follow the chart for the correct Domin replacement. If you have a Moog, Atos, or Woodward valve, see the charts on their respective pages.

Switching to Domin offers meaningful gains in both size and performance. For example, replacing a Bosch Rexroth 4WRPEH 6 with an S6 Pro can increase flow by up to 50%. Similarly, upgrading from an Parker D1FP to an S6 Pro can give you an 89% weight savings. Moving to an S10 Pro means size savings, no matter which brand you are upgrading from (Bosch Rexroth 4WRPEH 10: 42% smaller; Parker D3FP: 16% lighter).
