OMFB Twin Flow 70+53 Bypass Valve 12V – For Dual-Delivery Piston Pumps

The Twin Flow Bypass Valve 12V is designed specifically for use with dual-delivery bent axis piston pumps where the pump operates continuously, even when hydraulic demand is reduced or paused. Ideal for live drive PTO systems, this bypass valve helps prevent overheating and energy waste by partially recirculating internal flow during low-demand operation.

It’s a critical component for twin-flow systems, ensuring that each delivery circuit operates efficiently without overloading the system’s plumbing. Whether the system is powered via a direct engine connection or live PTO, the Twin Flow Bypass Valve maintains safe pressures and ensures proper cooling — especially in high-flow, high-pressure hydraulic setups.

Key Features:

• • Compatible with Twin-Flow pump models: 70+53

  • Designed for continuous-use applications where both circuits are active

  • Bypass recirculation per delivery, preventing system overload and excess heat

  • Operates via 12V Deutsch connector solenoid

  • Maximum pressure: 400 bar

  • IP66 rated for use in harsh mobile hydraulic environments

  • Minimum return flow of 5–10 L/min required for cooling

  • Includes emergency push-and-twist override for safety

  • Pressure port (3/8”) allows optional pressure gauge installation

  • Supplied with pressure hose, o-rings, and mounting hardware
