Rexroth DRV6, DRV8, DRV10, DRV12, DRV16, DRV20, DRV25, DRV30 flow control valve is to control the fluid flow rate by changing the throttle orifice area of valve. The flow control valve and check valve in parallel can be combined into throttle check valve. The throttle flow negative feedback function, the speed can not compensate for load changes caused instability is generally used only for load changes little or less demanding speed stability system.
Rexroth DRV flow control valve performance requirements:
• Flow adjustment range, smooth flow pressure changes ;
• Small leakage, a small amount of internal and external leakage ;
• Adjust the torque is small , quick action .
• Flow adjustment range, smooth flow pressure changes ;

Rexroth DRV6, DRV8, DRV10, DRV12, DRV16, DRV20, DRV25, DRV30 Flow Control Valve
The Rexroth DRV flow control valve has the following characteristics:
1. Simple structure, easy to manufacture and maintenance, and low cost.
2. Regulation accuracy is not high, and can not be adjusted in a wild range.
3. The sealing surface is easily eroded.
4. Poor sealing capacity.
The flow control valve according to the way of the channel can be divided into two kinds of straight-through and angle; shape by opening and closing parts, and needle, groove shaped.

Installation and maintenance of the Rexroth DRV flow control valve should note the following:
The valve often requires operation, therefore it should be installed on the easily operating position.
When installation, the valves should be paid attention to the same of medium flow with the valve body as the arrow in the same direction way.
