The XAi Series by-pass valve delivers the same proven functionality as the XPi version, specifically adapted for SAE-mounted pump configurations. It ensures safe, efficient operation in systems where the PTO runs continuously, protecting both the pump and hydraulic circuit.

Key Features

• Designed for XAi SAE-mounted bent axis pumps

• Rear-mounted integration for compact installation

• 24V solenoid operation (standard configuration)

• Compatible with XAi range from 12cc to 63cc

• Built-in drain port for correct oil management

Function & Operation

• In the inactive state, flow is diverted internally from outlet to inlet

• This prevents heat build-up and unnecessary system load

• When activated, the valve switches to allow normal pump output flow

• Requires a dedicated drain line to tank to maintain cooling and efficiency

This configuration allows continuous PTO-driven systems to operate safely without modifying the hydraulic circuit.

Benefits

• Prevents overheating and oil degradation

• Protects pump components under idle conditions

• Enables continuous PTO operation without load

• Simple installation with no system redesign required

Typical Applications

• SAE PTO truck installations

• Hydraulic systems with constant engine-driven pumps

• Applications requiring reliable standby hydraulic capability
