REXROTH Z2FS 6 A2-44/2QV R900439389

<h2>Rexroth Z2FS 6 Pilot Operated Throttle Check Valve</h2> <h3>Description</h3> <p>This is a Z2FS 6 A2-44/2QV sandwich plate valve from Bosch Rexroth, a leading manufacturer in drive and control technologies. It is a pilot-operated throttle check valve designed to control the flow rate of an actuator in one direction while allowing free flow in the opposite direction. This model offers meter-in control in both A and B ports, making it ideal for applications requiring precise speed control of hydraulic cylinders or motors. The NG6 (CETOP 3) mounting pattern ensures easy integration into standard hydraulic manifolds.</p> <h3>Specifications</h3> <ul> <li>Manufacturer: Rexroth</li> <li>Type: Z2FS 6 A2-44/2QV</li> <li>Part Number (MNR): R900439389</li> <li>Valve Type: Pilot Operated Throttle Check Valve</li> <li>Mounting: Sandwich plate design</li> <li>Nominal Size: NG6 (CETOP 3)</li> <li>Maximum Operating Pressure: 315 bar</li> <li>Adjustment: Screw with lock nut</li> <li>Seal Material: FKM (Viton)</li> </ul> <h3>Label Info</h3> <ul> <li>FD: 45516</li> <li>Serial: 124301846</li> </ul> <h3>Application</h3> <p>Suitable for use in general industrial machinery, machine tools, presses, and material handling equipment where precise speed control of hydraulic actuators is required.</p> <h3>Country of Origin</h3> <p>Made in Germany</p> <h3>CO2 Impact</h3> <p>By purchasing this pre-owned valve, you are contributing to a circular economy and helping to avoid 3.6 kg of CO2 emissions associated with new production.

Always confirm with the specific product datasheet for your application.</p> <strong>What type of hydraulic fluid is compatible with the FKM (Viton) seals?</strong><br><p>FKM (Viton) seals are compatible with a wide range of hydraulic fluids, including mineral oils (HL, HLP), synthetic esters, and water glycols. They offer excellent temperature and chemical resistance.</p> <strong>How do I adjust the flow rate on this valve?</strong><br><p>The flow rate is adjusted by turning the setscrew on the side of the valve. Turning it clockwise typically reduces the flow (throttles more), while turning it counter-clockwise increases the flow.</p> <p><em>profideals is not an authorized distributor, reseller or representative of the products featured on this website.
