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.

FAQ

Question?
What is the function of the check valve in this one-way flow control valve?

Answer

The 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?

Answer

For 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?

Answer

This 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.
