Oil relief valve PV48 series

for hydraulic systemspilot-operatedhydraulic

Overview
PV48 series is a pressure-reducing pilot valve designed to control multiple spool control valves and to adjust the tilting angle of variable displacement pumps simultaneously. The series includes PV48K (joystick type) and PV48M (compact joystick) models suited for construction and mobile machinery hydraulic systems.

Features

• Operational torque can be reduced according to customer requirements (patent registered), enabling fine control.
• Reduced pressure drop and quick response for improved control sensitivity (US Pat. No. 6,125,886).
