Collar Cementing Valve is applied for collar cementing of liners and is used as a whole
with the packer PMC or PMC-R.
The valve opens hydraulically by pressure build-up. The valve closes automatically
at any moment when outer annular pressure is higher than pipe pressure. Final valve
closing and fixation in the set position are performed when a cementing plug is set
into a seat in the valve.
