REXROTH 0 821 200 016

Rexroth One-Way Flow Control Valve for Pneumatic Systems Description This is a high-quality one-way flow control valve, also known as a throttle check valve, from Rexroth, part number 0 821 200 016. It is engineered to precisely control the speed of pneumatic cylinders and other actuators by restricting the flow of compressed air in one direction while allowing free, unrestricted flow in the opposite direction. The valve features a durable die-cast aluminum body and an easy-to-use red adjustment knob for fine-tuning performance. Specifications Manufacturer: Rexroth (now part of Emerson Aventics) Part Number: 0 821 200 016 Type: One-Way Flow Control Valve Series: GRLA Port Connection: G 1/2 Inch Female Thread Maximum Operating Pressure: 10 bar (145 psi) Operating Temperature: -20 to +80 deg Celsius Housing Material: Die-cast aluminum Seals: Nitrile rubber (NBR) Label Info Brand: Rexroth Model: 0 821 200 016 Serial/Batch: 9180 / 887 Application This valve is ideal for applications requiring differential speed control of pneumatic actuators, such as controlling the extension and retraction speeds of a pneumatic cylinder. It is commonly used in industrial automation, machine building, material handling, and assembly lines. Country of Origin Made in France CO2 Impact By choosing this pre-owned component, you are preventing the emission of approximately 4.8 kg of CO2, which would have been generated during the production of a new one. This is a sustainable choice for your operations. Availability This item is in stock and ready for immediate dispatch. Order now from profideals for expert support and fast delivery. FAQ Question?What is the function of the check valve in this one-way flow control valve?AnswerThe integrated check valve allows for unrestricted, free flow of compressed air in the reverse direction, bypassing the throttle. This is typically used to have a slow extension and a fast retraction of a pneumatic cylinder, or vice-versa. Question?How do I correctly install the Rexroth 0 821 200 016 to control the speed of a cylinder?AnswerFor meter-out control (smoothest operation), install the valve on the exhaust port of the cylinder. The flow should be restricted as air leaves the cylinder. For meter-in control, install it on the supply port to restrict the incoming air. Question?Can this valve be used with media other than compressed air?AnswerThis valve is specifically designed and sealed for use with filtered, lubricated or non-lubricated compressed air. Using it with other media like water, oil, or aggressive gases is not recommended and can cause damage or malfunction. profideals is not an authorized distributor, reseller or representative of the products featured on this website.
