Rexroth 2 FRM 10-31/25 L 2 Way Hydraulic Flow Control Valve R900423255

Rexroth 2FRM10-3X/25L 2-Way Hydraulic Flow Control Valve (R900423255)

The Rexroth 2FRM10-3X/25L is a precision-engineered 2-way hydraulic flow control valve designed to maintain a consistent flow rate, largely independent of pressure and temperature variations. This valve is ideal for applications requiring reliable and accurate flow regulation.

Key Features

• Size and Series: Size 10, Component Series 3X
• Flow Capacity: Maximum flow rate of 25 liters per minute
• Pressure Rating: Maximum operating pressure of 315 bar
• Actuation Type: Mechanical actuation for straightforward operation
• Mounting: Subplate mounting with porting pattern compliant with DIN 24340 form G and ISO 6263 standards
• Temperature Independence: Orifice design at the throttling point ensures consistent performance across varying temperatures
• Return Flow Management: Integrated check valve allows free return flow from channel B to A without affecting regulated flow direction

Design and Functionality

The 2FRM10-3X/25L valve comprises several key components:

• Housing: Robust construction for durability
• Orifice Bush: Facilitates precise flow control
• Pressure Compensator: Ensures pressure-independent flow at the throttling point
• Check Valve: Manages return flow effectively
• Adjustment Element: Allows mechanical setting of the throttle cross-section

Flow regulation from channel A to B is achieved by adjusting the throttle cross-section via the curved bolt and adjustment element. The pressure compensator maintains a constant flow rate, while the orifice design ensures temperature stability. For applications involving oscillating flows, a rectifier sandwich plate type Z4S can be installed beneath the flow control valve.

Technical Specifications

• Maximum Flow: 25 liters per minute
• Maximum Operating Pressure: 315 bar
• Weight: Approximately 3.35 kg
• Seal Material: NBR seals compatible with various hydraulic fluids, including HL, HLP, HLPD, HVLP, HVLPD, and HFC

The Rexroth 2FRM10-3X/25L valve is a reliable solution for maintaining consistent hydraulic flow rates, offering robust performance and adaptability to various industrial applications.
