Q1: What is the difference between "A" and "B" versions of 2FRM6?
A:
2FRM6A… = Throttling in A → A₁ direction (meter-in on Port A). Used when the valve is stacked on the A-port side between directional valve and subplate.
2FRM6B… = Throttling in B → B₁ direction (meter-in on Port B).
For speed control on both extend and retract, two valves (one A + one B) are typically stacked. The free-flow return direction always has an open check valve.
Q2: Why does this valve need an external drain (Y port) and what happens if I omit it?
A: The pressure compensator spool balances spring force against pilot/drain pressure. The Y port must be connected directly to tank with zero backpressure. If Y is blocked or sees backpressure, the compensator cannot function correctly → flow becomes pressure-dependent and unstable. Never 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 that maintains a constant pressure drop across the metering orifice. This means the set flow stays constant despite load pressure changeson P or A ports. A Z2FS6 is a simple needle/throttle — flow varies with ∆P. Use 2FRM when consistent speed under varying load is required; use Z2FS for coarse, cost-sensitive throttling.
Q4: What is the practical meaning of the "3Q" flow code?
A: /3Q sets the maximum adjustable flow to 3 L/min. The usable range is approx. 0.05–3.0 L/min. Select the Q-code closest to your required max flow — a smaller Q-range gives better fine-adjustment resolution. If you need 6 or 16 L/min, choose /6Q or /16Q variants. Do not try to use a 3Q valve for flows >3 L/min.
Q5: Why FKM (Viton) seals on this valve?
A: The V suffix = FKM seals, required for:
Service 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, the NBR version is acceptable. The FKM version (this part) provides broader fluid compatibility and higher temp rating — choose based on your fluid & temperature.
