D771X: Modular Hydraulic Butterfly Valve Platform
The D771X Series represents a new standard in integrated valve automation. By pairing our high-performance butterfly valves with the T, S, or D series hydraulic actuators, INJOY provides a modular system that adapts to your specific environment. Whether for space-constrained engine rooms or high-pressure subsea manifolds, the D771X ensures precision control and long-term durability.

For ultra-high pressure or special subsea requirements (330m+), please contact our technical team for custom D-series solutions.
Optional PFB Feedback Module
Every D771X configuration can be equipped with our PFB module, providing 0-100% real-time position confirmation for centralized bridge or engine room control. Our native integration ensures that the actuator and feedback system operate as a single, high-integrity unit.
Triple-Layer Defense
Proprietary Solid-State Encapsulation and redundant internal sealing; ensures bone-dry operation under extreme hydrostatic pressure and condensation.
German P+F Precision
Integrated with premium Pepperl+Fuchs analog sensors for continuous 4-20mA position visibility.
Heavy-Duty Construction
Cast in C95800 Nickel-Aluminum Bronze with 316L Stainless Steel interfaces; immune to seawater corrosion and biofouling.
Operational Depth
IP68 Rated and system-verified for depths up to 330 Meters / 1,083 Feet (D-Series with Bronze Top Cap). We offer tiered testing for T-Series (5m) and S-Series (50m) to match your specific offshore requirements.
