Balancing valve MCBBD series

Product catalog summary

Specifications

Operating Pressure: 350 BAR
Flow: 40 L/min
Internal Leakage: 0.3 ml/min max to 85% of nominal setting
Pilot Ratio: 4.5:1
Temperature Range: -40°C to +120°C (-40°F to +250°F)
Cavity: T-11A
Fluids: Mineral-based fluids with viscosities of 7.4 to 420 cSt

Features

The balance valve setting should be at least 1.3 times the load pressure.
Backpressure at port 2 increases the relief setting by (1 + pilot ratio) times the backpressure.
Reseat pressure exceeds 85% of set pressure under standard settings; lower settings may reduce reseat percentages.

Operation

The counterbalance valve with pilot assist is designed to control an overrunning load. It allows free flow from the directional valve (port 2) to the load (port 1) and controls flow from port 1 to port 2 using a direct-acting, pilot-assisted relief valve. Pilot assist at port 3 reduces the effective relief valve setting based on the pilot ratio.

Performance Curve

The performance curve illustrates the relationship between pressure drop and flow rate, indicating how pressure drop varies with changes in flow.

Installation Dimensions

Details on installation dimensions and torque specifications are provided, including the number of counter-clockwise turns and maximum torque values for different hex sizes.
