Q1: What is the difference between "A" and "B" versions of 2FRM6?
A:
2FRM6A… = Throttling in A → A₁ direction (meter-in on Port A side). Stacked between directional valve and subplate on the A-port.
2FRM6B… = Throttling in B → B₁ direction (meter-in on Port B side).
For independent speed control on both extend and retract strokes, one A-version and one B-version are typically stacked together. The reverse flow always passes through a free-flow check valve with no restriction.
Q2: Why is an external drain (Y port) required and what if I don't connect it?
A: The pressure compensator spool needs a reference to tank pressure. The Y port must be plumbed directly to the reservoir with zero backpressure. If Y is blocked, the compensator spool cannot balance → flow becomes pressure-sensitive, unstable, or the valve may fail to regulate. Never omit or plug the Y port on a 2FRM valve.
Q3: How is this different from a Z2FS6 needle throttle valve?
A: The 2FRM6 has a pressure compensator maintaining constant ∆P across the metering orifice, so set flow remains constant despite load pressure changes on P or A ports. A Z2FS6 is a simple needle throttle — flow varies with pressure drop. Use 2FRM when consistent actuator speed under varying load is critical; use Z2FS for basic, cost-sensitive throttling.
Q4: What does the "6Q" flow code mean in practice?
A: /6Q sets the maximum adjustable flow to 6 L/min (usable range approx. 0.2–6.0 L/min). Select the Q-code matching your required max flow — a smaller Q-range (e.g. /1.5Q, /3Q) gives finer adjustment resolution. If your appliion needs >6 L/min, choose /16Q. Do not force a 6Q valve beyond its rated max or the orifice will be wide open with no regulation.
Q5: Why specify FKM (Viton) seals — is NBR not enough?
A: The V suffix = FKM seals, required for:
Temperatures above +70°C (up to +80°C)
Water glycol (HFC) or phosphate ester (HFD) fire-resistant fluids
For standard mineral oil (HL/HLP) at normal temps, NBR is acceptable. The FKM version (this part R983032397) offers broader fluid compatibility and higher temp rating — select based on your actual hydraulic fluid.
