FAQ — Frequently Asked Questions

Q1: What is the difference between "S", "S2", and "P/T" versions?

A:

  • S / S2​ = Main flow limitation​ — both working ports A and B have throttle/check combos to control actuator speed. "S2" is typically a later variant with refined adjustment or internal details.

  • P​ = Pilot flow limitation (throttles pilot lines of pilot-operated directional valves).

  • T​ = Tank line throttling.

    Choose S/S2 for controlling cylinder or motor speed; choose P for adjusting valve switching time.

Q2: How is this valve installed in the stack?

A:​ Place the Z2FS10 between an NG10 directional control valve and its subplate/manifold. The side marked toward the directional valve contains the adjustable orifices (throttled direction A₁→A₂, B₁→B₂); the opposite side (facing subplate) contains the free-flow check valves. Tighten the four M6 bolts evenly to ~20–25 Nm in a cross pattern.

Q3: Which direction is throttled and which is free-flow?

A:​ Flow from the directional valve (A₁/B₁) toward the actuator (A₂/B₂)​ passes through the adjustable needle orifice — use this to set speed. The reverse flow (actuator → directional valve)​ lifts the check valve seat and returns unrestricted (no restriction). Need reverse-direction speed control? Add a second Z2FS on top or use a meter-in/meter-out circuit layout.

Q4: Why would I choose the FKM (Viton) version over the standard NBR version?

A:​ The V suffix = FKM seals, which resist:

  • Higher temperatures (up to +80°C vs. +70°C for NBR)

  • Water glycol (HFC)​ and phosphate ester (HFD)​ fire-resistant fluids

    If you're using standard mineral oil only, the NBR version is adequate and lower cost. For HFC/HFD or high-temp service, FKM (this part) is required.

Q5: What causes unstable speed or valve blockage?

A:​ Main causes:

  1. Contamination​ — the needle orifice is very small; maintain ISO 4406 20/18/15 and use a 10 µm return filter.

  2. Lock nut over-tightened​ — can shift the spindle setting; snug only.

  3. Pressure fluctuation​ — needle throttles are notpressure-compensated; large ∆P swings affect flow slightly (use a pressure-compensated flow control if tight speed regulation is needed).
