Valvehead Comparison – T handle, Tamper Resistant, Lockable
This is the ‘standard’ handle and allows easy operation of the valve by anyone.
Tamper Resistant handle
This features a removable ‘Key’ handle, once the key is removed, operation of the valve is not possible without the key short of destroying the valvehead.
This combines the T handle with an option to lock. Pulling up on the T handle exposes an opening for a lock. Once locked, the valve cannot be operated without removing the lock.
