Jun 19, 2013 · Stroke Volume (SV) is the volume of blood in millilitres ejected from the each ventricle due to the contraction of the heart muscle which compresses these ventricles. This can lead to improper or uneven closure of the heart valve. Designed to cut off the air flow to the tipping valve and therefore stop the raise when the cylinder arrives at the planned position, this system is normally used as an alternative to the end of stroke cable connected to the spool of the tipping gear. FC V NA. r. operating pressure bar (psi) 250 (3600) Max. In rest position the valves interrupt the oil flow. V-FCR 1T. C - preignition and burned valves. SV is the difference between end diastolic volume (EDV) and end systolic volume (ESV). Significant wear can occur over time and lead to performance losses. dual sealing valve: A valve that uses a resilient seating material for the primary seal and a metal-to-metal seat for a secondary seal. Valvular prolapse (slipping out of place) Prolapse is a condition when the valve flaps (leaflets) slip out of place or form a bulge. In the rest position, thanks to the poppet, they guarantee the pressure seal. Pneumatic Actuated Valves. The stem is treated with Niploy.
