FAQ

Question?

What does the ‘2QV’ designation in the model number Z2FSK 10-2-12/2QV signify?

The ‘2Q’ indicates that this valve provides throttling in both the supply and return lines (A and B ports), allowing for meter-in and meter-out control. The ‘V’ specifies that the seals are made from FKM (Viton), which are suitable for a wide range of hydraulic fluids and higher temperatures.

Question?

What is the maximum operating pressure for this NG10 valve?

This valve is designed for a maximum operating pressure of 315 bar (approximately 4568 PSI), which is standard for many industrial hydraulic applications using NG10 components.

Question?

How do I correctly install this sandwich plate valve in my hydraulic circuit?

This valve has a porting pattern according to ISO 4401-05-04-0-05. It should be ‘sandwiched’ between a subplate (or manifold block) and a directional control valve of the same NG10 size. Ensure all surfaces are clean, O-rings are correctly seated, and mounting bolts are torqued to the manufacturer’s specification to prevent leaks.
