Triton ACS - Accumulator Charging System
The Triton ACS - Accumulator Charging Systems is compromised of dedicated tooling for installation (Torque Tool) and charging (Charging Head). Torque and Charging operations have been purposely separated to provide enhanced HSE features only available with the Triton ACS system.
Both tools rely on internal hex head jacking bolts that thread into the top of the Triton ACV and lock the tool and valve together. The length of the bolts in the tools provide timing for torque and charging operations. Various aspects of required tooling provide unique and desirable HSE benefits to prevent close calls and injuries. Tooling also eliminates the ability of the user to damage the sealing mechanism resulting in a long trouble free field life.

Triton Torque Tool
HSE Audible Warning - prevents unscrewing a valve containing pressure. By design the valve stem must be cracked open prior to torque dog engagement.
Triton Charging Tool
The Triton Charging Tool is unique and is required to direct incoming gas pressure through the side port on a Triton ACV. The Triton Charging tool adapts to and provides a threaded connection for common charging kits already being used on rigs. As an HSE feature the Charging Tool does not have torque pins so it has no ability to apply unscrewing torque to a Triton ACV.
For charging operations the Jacking bolt must be turned to a full stop prior to the application of charging pressure. A full stop opens the valve and blocks it open mechanically. If charging pressure is applied to a valve not blocked open mechanically by the jacking bolt then the bias piston in the ACV will cause the valve to shut immediately blocking gas pressure from entering the bottle. No amount of gas force can open the valve as it only tries to close harder as the gas pressure increases.
Basic Operation of the Triton 10 Series ACV
Bolt Force Opens Valve vs Bottle Pressure
Gas Force From Bottle Closes Valve as bolt force is backed out.
Bolt force (in the Triton Tooling) is used to mechanically open the valve. Gas force from the bottle closes closes the valve. Triton Gas Valves are self-seating and self-sealing. There is no ability to close the Triton ACV mechanically. User cannot damage the sealing mechanism by accidentally over-tightening.
Subsea Close Assist - Triton 10 Series ACV
Triton 10 Series Slimline valve has subsea close assist to prevent the gas valve from opening if the bottle is in an under-balanced conditi. Under-balanced is Hydrostatic > Bottle Pressure. Typically this only applies to DCB - Depth Compensated Bottles. How does the subsea close assist work?
After Charging is complete an SAE cap with oring is installed.
Atmospheric reference is trapped in atmoshperic chamber between SAE cap and top of bias piston.
As valve is run subsea hydrostatic pressure enters main valve chamber between bias piston and stem seal.
Bias piston has 1.44X more surface area than stem seal so hydrostatic is exerting more closing force than opening force.
The deeper the valve goes the harder it tries to close.
