Using an Allen Key, how to reduce the force on a gas spring equipped with a T-Valve
Do NOT use this method for gas springs equipped with a Schrader Valve. If you are unsure which valve you have, click here.
On this video we are using a 3mm Allen Key and a small hammer to gently tap on the key. As you can see the valve is not very deep inside and you should be able to use either sides of the Allen Key to reduce the force. If you do not have a 3mm allen key, a smaller one can also be used.
Each time you hear the gas escape, some force is reduced. On small gas springs with a small gas chamber the force goes down quickly so you should go slowly and make as many trials as necessary.
Using an Allen Key, how to reduce the force on a gas spring equipped with a Ball Valve
On this video we are using a 1.5mm Allen Key and a small hammer to gently tap on the key. As you can see the valve is not very deep inside the thread and you can usually use either sides of the Allen Key to reduce the force.
Each time you hear the gas escape, some force is reduced. On small gas springs with a small gas chamber the force goes down quickly so you should go slowly and make as many trials as necessary.
The product shown on this video is a 250mm stroke gate gas spring.
IGS Gas spring equipped with a Side Release Valve (SRV)
How to reduce the force on a gas spring equipped with a Side Release Valve.
On this video we are reducing the force of 2 small size 6 gas springs with a 100mm stroke. When used on larger gas springs, the force goes down in much smaller steps.
The tool used to actuate the grub screw is a standard 2mm Allen Key.
On small gas springs with a small gas chamber the force goes down quickly so you should go slowly and make as many trials as necessary. It took more than 5 minutes to reduce the force from exactly 150 newtons down to 108 newtons in each gas spring.
This is work in progress, we will update this video as soon as we can find better actors!
IGS Gas spring equipped with a Ball Valve (BV)
How to reduce the force on a gas spring equipped with a Ball Valve.
On this video we are using a 1.8mm drill bit and a small hammer to gently tap on the drill bit, you can also use a 1.5mm Allen key if you don't have 1.5-1.8mm drill bits available.
Each time you hear the gas escape some force is reduced. On small gas springs with a small gas chamber the force goes down quickly so you should go slowly and make as many trials as necessary.
Box application - Using 2 different damped gas springs
Two steps damping:
Gas spring at the back is damping from 30 degrees to 70 degrees.
Because the centre of gravity of the lid goes over centre, the second gas spring has some very strong damping to damp the last 20 degrees.
