most certainly you can get one from one of these suppliers:\nhttp://www.mmacactuators.com/\nhttp://www.motioncontrol.com/\nhttp://www.rotork.com/products/linear/index.cfm\n\ni found these by just searching around on the web.  the catalogues might specify the technical details you want to know, but in almost all cases like this, the thing you want to do is CALL the place up and ask to speak to a sales engineer.  they are a person who works in sales but has engineering training so they won't go "durrr" when you start talking about Newtons and so on.  their job is to help you in exactly the way you need.\n\nanyway good luck!

There is a Yahoo discussion group called Pumpsters just for people with Medtronics pumps and that is where you need to go for discussion of your options.  good luck\n\nhttp://groups.yahoo.com/group/pumpsters/

I found a 1" butterfly valve and an on-line head loss calculator, but it doesn't ahve everything you need.

Menshealth.com. They have a position master where you can select difficulty of position, stimulation, primary thruster etc. It's good times.

Hydraulic Cylinders \nHydraulic cylinders are actuaion devices that utilize pressurized hydraulic fluid to produce linear motion and force. Search by Specification | Learn more about Hydraulic Cylinders \n \nHydraulic Pumps \nHydraulic pumps deliver high-pressure fluid flow to the pump outlet. Hydraulic pumps are powered by mechanical energy sources to pressurize fluid. Search by Specification | Learn more about Hydraulic Pumps \n \nHydraulic Valves -\nHydraulic valves contain and transfer the flow and pressure of hydraulic fluid in hydraulic power systems. They range from simple shutoff valves to precision control valves. Search by Specification | Learn more about Hydraulic Valves \n \nHydraulic Motors - \nHydraulic motors are powered by pressurized hydraulic fluid and transfer rotational kinetic energy to mechanical devices. Search by Specification | Learn more about Hydraulic Motors \n \nHydraulic Regulators \nHydraulic regulators maintain the output pressure at a set value. Learn more about Hydraulic Regulators \n \nHydraulic Reservoirs - \nHydraulic reservoirs are storage tanks that hold liquids or gases used in fluid power applications. They are usually rectangular, cylindrical, T-shaped, or L-shaped and made of steel, stainless steel, aluminum, or plastic.  \nHydraulic Accumulators - \nHydraulic accumulators use an incompressible fluid and a compressed gas, spring or raised mass to store energy, absorb shock, eliminate noise, and counter-balance loads. \nElectrohydraulic Valve Actuators and Hydraulic Valve Actuators - \nElectrohydraulic valve actuators and hydraulic valve actuators convert fluid pressure supply pressure into motion. \n \n \nHydraulic Rotary Actuators -\nHydraulic rotary actuators use a pressurized, incompressible fluid to rotate mechanical components.

Your subject is somewhat vague, but I believe the web site below can help.\nEnter Valve into their search window. Several device manufacturers are mentioned.\nHope this helps.

leftknight is about right, but it uses hydraulic fluid, not water. These presses range from small hand-pumped laboratory units to huge monsters with thousands of tons force. They are used in metal forming and making bricks and structural concrete pieces.
