API 6A Hydraulic Actuator
Designed and engineered for severe-service valve automation applications. The API 6A Hydraulic actuator has nominal pressures of 3,000 PSI / 5,000 PSI.
Self-Contained ESD System
The Self-Contained ESD System of the API 6A Hydraulic Actuator is a safety system that is designed to provide reliable valve shutdown capability when an external power source is either not available or not dependable. Using a hand pump with different control parts, a zero leakage circuit is maintained to ensure valve movement does not inadvertently occur until a fail-safe signal is received.
From the Arctic to the desert, proven seal compounds for a wide variety of applications.
Easy to Operate
The Self-Contained ESD System, with its sequence valve and bypass valve, can directly pressurize and open the valve conveniently in spite of external conditions.
All control system components of the hydraulic actuator are integrated on one manifold, with all channel connections among each part designed within the module. The structure is compact, reliable and no leakage even in extremely high or low ambient temperature.
With volume compensating design, the hydraulic control loop is totally isolated with air, avoiding deterioration or contamination of the hydraulic oil. The C6A can be installed at any angle necessary.
Temperature compensation of high pressure hydraulic actuator circuit and low pressure control circuit is accomplished with two separate accumulators. This assures system stability by minimizing relief valve operation and eliminating valve drift due to large temperature changes.
Fast Trouble Shooting
Specialized troubleshooting design provides a quick self-diagnosis system.
