Solenoid Shut Off Valve for Evo/Evo+ (with Medium C/Lungs)
Product Code: GC6/EV/M
Solenoid Shut Off Valve for Evolution or Evolution Plus (with Medium counterlungs) - Complete Assembly
The purpose of this valve is to allow the user to shut off the supply of oxygen to the solenoid without cutting the supply of oxygen to the manual inflator or the oxygen contents gauge.
If the solenoid free-flows during a dive, the supply of oxygen can be shut off to the solenoid and the diver can still add gas manually using the oxygen inflator on the exhale counterlung. Manual oxygen injection as a dive-abort procedure will have been covered on your training course. Refer to your instructor/training agency/manual for full details.
The Solenoid Shut Off Valve consists of 4 parts:
1. GC6 Manifold
2. GC3 Flowstop Shut Off Valve
3. Medium Pressure Supply Hose (from Oxygen first stage to GC6 Manifold)
4. Solenoid Hose (from solenoid to GC6 Manifold) c/w yellow locking clip
During normal diving conditions, the shut off valve should be in the fully OPEN position to allow the solenoid to function in the normal way. The yellow shut off valve clip MUST be clipped onto the GC3 shut off valve to prevent inadvertent operation to the closed position. (See image right)
Shut Off Operation
If the solenoid malfunctions, pull the yellow shut off valve clip from the GC3 shut off valve and slide the valve collar to the CLOSED position, cutting off the supply of oxygen to the solenoid. As a precaution the yellow shut off valve clip MUST be re-inserted into the GC3 shut off valve to prevent the collar from being moved inadvertently back to the open position. (See image right)
The diver should now abort the dive, using the oxygen inflator to inject oxygen into the breathing loop manually, as covered in your training.
IMPORTANT NOTE: When ordering you need to ensure you choose the correct assembly (with the right size hoses) for your unit and counterlung size. The Shut Off Valve assembly on this page fits an Evolution or Evolution Plus with Medium counterlungs.
