  • Overview

The SONGEE Plate-Type Bidirectional Balancing Valve is a compact, high-performance hydraulic component designed to provide controlled flow in both directions.

It balances flow for smooth actuator movement, prevents runaway loads, and maintains stability under varying load conditions.

Main Features

  • Bidirectional flow control for stable motion
  • Compact plate-type design for easy installation
  • Hardened internal components for long service life
  • Excellent load holding and cavitation resistance
  • Suitable for mobile and industrial hydraulic systems

Models and Specifications

Model Max Pressure Rated Flow Ratio Port Size Weight
PTBV-12L 350 bar 60 L/min 4:1 G1/2″ 0.65 kg
PTBV-15L 350 bar 100 L/min 4:1 G3/4″ 0.95 kg
PTBV-18L 350 bar 160 L/min 4:1 G1″ 1.45 kg

Note: Rated flow values are based on the free-flow direction. Pilot-assisted flow is reduced according to the ratio.

Load Holding

  • Provides reliable load holding in both directions
  • Prevents uncontrolled movement of actuators under load

Motion Control

  • Ensures smooth extension and retraction of hydraulic actuators
  • Reduces shock and improves system stability

Installation

  • Connect P1 and P2 to the actuator ports
  • Can be mounted in any orientation
  • Ensure system cleanliness and use appropriate filtration
