Page 7: Theory Of Operation
MV600 Series Metering Valve PVA Theory of Operation The MV600 is a rod displacement style, positive displacement metering head with two integral check valves to control the flow of material into and out of the valve. A spring loaded check valve mounted to the metering cylinder act’s as the inlet check valve and the SB300 series rear closing dispense valve acts as the outlet check valve. The metering chamber houses a rod and cylinder combination to meter a specific amount of material to be dispensed. A micrometer in the upper air section is adjusted to set the travel distance of the rod thus setting the chamber volume that will displace a specific fluid volume during each cycle. During fill, the SB300 dispense valve will stay closed as fluid pressure is used to push the piston upward until it reaches the micrometer “hard stop”. An air port on the metering chamber is available for refill assist to pull fluid into the metering section faster. Once filled, air pressure is simultaneously applied to the SB300 to cycle it open and the air section of the metering chamber to drive the rod down and force fluid out of the valve. A second air port is located on the metering chamber to double the pressure used to drive the rod down to dispense. A stroke adjustment in the air section of the SB300 can be used to control the amount of suck back to prevent dripping and stringing with thicker fluids. Setup The MV600 requires a 2‐position, 4‐way air solenoid valve to actuate the air section. The valve should be operated with clean, dry air between 50‐100psi. Two #10‐32 threaded air ports are located on the air section of the SB300 valve and three #10‐32 ports are located on air section of the metering chamber. The port located on the side of the SB300 is air to close the valve. The port located on the top of the stroke adjustment is air to open the valve. The air supply connected to the stroke adjustment of the SB300 should be tied to the highest and lowest port on the air section of the metering chamber. The middle port of the metering chamber can be tied to the port on the side of the SB300 to provide refill assist. Quick connect air fittings are typically supplied with the MV600 to fit 5/32” tubing. Note that the valve should be normally in the closed position. Flow control air fittings can be used to control the speed of refill and dispense of fluid. Fluid is supplied to the MV600 through the 1/4”mnpt inlet check valve located on the inlet of the metering cylinder. Revision A (2018) 7 of 35... -
Page 8: Pneumatic Schematic
MV600 Series Metering Valve PVA Pneumatic Schematic There are three different options when connecting pneumatic to the MV600 series valve. The SB300 series outlet valve must always be connected to the solenoid but the metering cylinder contains to ports which can be used to drive fluid to dispense and one port which can be used to assist refilling fluid in the metering cylinder. Option 1: Used for highest viscosity fluids. Both dispense ports are connected providing a 40:1 ratio mechanical advantage for dispense pressure. Refill assist port is connected to pull fluid into the metering chamber faster. Table 2: Pneumatic Schematic – Dual Air Dispense & Refill Assist Revision A (2018) 8 of 35 ... - Page 9 MV600 Series Metering Valve PVA Option 2: Used for medium viscosity fluids. One dispense port is connected providing a 20:1 ratio mechanical advantage for dispense pressure. Refill assist port is connected to pull fluid into the metering chamber faster. Table 3: Pneumatic Schematic – Single Air Dispense & Refill Assist Option 3: Used for lower viscosity fluids. One dispense port is connected providing a 20:1 ratio mechanical advantage for dispense pressure. No refill assist is used.

Page 11: Valve Settings
MV600 Series Metering Valve PVA Valve Settings 1. Fluid pressure to valve inlet will determine piston refill time. Increasing fluid pressure will allow the metering chamber to fill at a faster rate. 2. Connecting the solenoid to the refill assist port as shown in table 2 or 3 to pull fluid in faster and decrease fill time. 3. Connect the solenoid to both air dispense ports as shown in table 2 in order to build the maximum amount of pressure to dispense fluid and decrease dispense time. 4. Turning the micrometer counter‐clockwise will increase the volume and turning it counter‐clockwise will decrease the fluid volume. Note: After each adjustment, cycle the valve one to dispense and check new volume. Note: Valve should be cycled to the open position when adjusting the micrometer so the piston is not being forced against the micrometer. -
