The QTM7 is a flow restrictor with built-in check valve, in ISO 4401-07 (CETOP 7) modular form. It fits in the stack, under the solenoid valve, held by the tie rods, without pipework.

The SA version controls the oil leaving the actuator on line A (meter-out); in the opposite direction the oil flows freely through the check valve. It is used to control the speed of large cylinders, especially with loads that tend to pull the cylinder.

Data from the Duplomatic series 10 datasheet; this item is series 20, so please check the values with us before ordering.

Maximum pressure: 350 bar
Maximum flow: 250 l/min
Check valve cracking pressure: 0.7 bar
N: NBR seals, for mineral oil
S: countersunk hexagon screw adjustment with locknut; turning anticlockwise increases the flow

For control on both lines there is the QTM7-D version.
