Flow control system and method for controlling the flow of liquid

A method for controlling a flow of liquid into a tubular member and from the tubular member, the method comprising:

• providing the tubular member having a perforated portion that is configured to distribute a flow of liquid having a predefined fixed liquid pressure (Pw) through the perforated portion, thereby pressurizing an intestine that is suspended on the tubular member;
• controlling the flow of liquid such that the pressure of liquid in the tubular member is maintained within a predefined pressure range (PW1-PW2) using a flow regulating valve comprising:
• a water inlet port for letting liquid into the flow regulating valve;
• a water outlet port for draining liquid from the flow regulating valve;
• a flow port in fluid communication with the tubular member;
• and
• a flow regulating member in fluid communication with the flow port, wherein the flow regulating member is configured and arranged to be positioned in:
• a) a first configuration, in which liquid from the water inlet port can flow into the flow regulating valve, wherein no liquid can be drained through the water outlet port;
• or
• b) a second configuration, in which liquid from the flow regulating valve can be drained through the water outlet port, wherein no liquid from the water inlet port can flow into the flow regulating valve;
• a force generating device connected to the flow regulating member such that motion of the force generating device causes motion of the flow regulating member;
• and
• a force countering device connected to the flow regulating member such that motion of the force countering device causes motion of the flow regulating member;
• and
• applying a predefined force (Fair) towards the force generating device using a force generating unit.
