Product Overview
The KOZO Marine Pneumatic & Hydraulic Trunnion Ball Valve is designed for offshore and marine remote-isolation duties where high operating torque, fail-safe action or emergency shutdown functions require a dedicated actuator package. The reference configuration uses a 12 in Class 300 trunnion valve with A105N body, metal seats, RF ends and a pneumatic/hydraulic operating system.
Actuation Concept
Pneumatic/hydraulic actuator packages can combine stored hydraulic energy, gas pressure or hydraulic control logic to provide remote operation and project-specific fail action. The exact actuator architecture should be selected from valve torque, available utilities, required closing time and safety philosophy.
Key Design Features
- Trunnion-mounted ball: Stable operating torque for larger valve sizes.
- Metal-seat configuration: Reference arrangement for demanding offshore service.
- Pneumatic/hydraulic actuation: Supports remote isolation and ESD integration.
- RF flanged ends: Reference connection for Class 300 piping.
- Split-body construction: Supports maintenance of seats and internals.

Selection Notes
Actuator sizing and fail action must be based on maximum valve torque, differential pressure, supply pressure, required stroke time and safety factor. Certification and explosion-protection claims should only be stated where the supplied actuator documentation confirms them.
How to Specify This Valve
Please provide valve size/class, medium, temperature, torque requirement if available, fail position, operating time, pneumatic/hydraulic supply conditions, control signal, accessories and project certification requirements.
