Description

The MOOG D136-001-007 is a high-response, two-stage electrohydraulic servo valve engineered for precision control of hydraulic actuators in demanding industrial, test, and simulation applications. As part of Moog’s renowned D136 series, this valve uses a robust jet pipe pilot stage—offering superior contamination tolerance compared to flapper-nozzle designs—making it ideal for harsh environments like steel processing, structural testing labs, and mobile heavy equipment.

With analog ±10 V command input, the D136-001-007 modulates flow proportionally to electrical signal, enabling closed-loop control of position, velocity, or force with exceptional linearity, low hysteresis, and millisecond-level response. It is widely trusted in applications where reliability, repeatability, and dynamic performance are non-negotiable.

Application Scenarios

At a European automotive crash test facility, inconsistent actuator response during sled tests caused data scatter in airbag deployment validation. The root cause was an aging servo valve with degraded spool dynamics. Engineers replaced it with a new MOOG D136-001-007. which restored flow linearity to ±0.4% and reduced step response time to 8.2 ms. Test repeatability improved by 92%, accelerating certification cycles by 3 weeks per vehicle model. In another case, a Japanese steel mill used the D136-001-007 to control hydraulic down-coilers handling 1.200°C slabs. Despite ambient temperatures exceeding 70°C and fluid cleanliness at ISO 19/17/14. the valve operated continuously for 18 months without maintenance—demonstrating Moog’s legendary ruggedness.
