Upgrade Your Moog Valve to a Domin Servo Valve

Replacing a Moog servo valve on an injection molding press is an opportunity to improve response, reliability, and operating efficiency. Domin servo valves function as drop-in upgrades for existing Moog valves with higher performance, lower energy loss, and reliable control without a full system redesign.

There are a lot of factors to consider in choosing a servo valve replacement or upgrade, including mounting capability and technical specifications. However, it’s not just about whether or not the valve fits in your system; it’s important to consider how the system or product can benefit in terms of performance, response time, cost of ownership, and more. Discover how Domin valves eliminate the tradeoffs in traditional two stage and direct drive valves.

Domin valves are designed as direct drop-in replacements for competitor brands such as Moog due to their standard port patterns and straightforward integration process.

Through local inventory and Domin’s lead time zero initiative, Moog valves can be replaced in days. If you have a Moog model below, follow the chart for the correct Domin replacement.

Switching to Domin offers meaningful gains in both size and performance. For example, upgrading from a Moog G771 to an S4 Pro can result in a 25% faster step response. Similarly, replacing a Moog D633 to the P6 Pro can result in a 75% lighter package.
