MCBBD

Features The setting value of the balance valve should be at least 1.3 times of the load pressure value. Backpressure at port 2 adds to the effective relief setting at a ratio of 1 plus the pilot ratio times the backpressure Reseat exceeds 85% of set pressure when the valve is standard set. Settings lower than the standard set pressure may result in lower reseat percentages

Features

The setting value of the balance valve should be at least 1.3

times of the load pressure value.

Backpressure at port 2 adds to the effective relief setting at a ratio

of 1 plus the pilot ratio times the backpressure

Reseat exceeds 85% of set pressure when the valve is standard

set. Settings lower than the standard set pressure may result in

lower reseat percentages

Operation

Counterbalance Valve with pilot assist are meant to control an overrunning

load. The check valve allows free flow from the directional valve (port 2) to the

load (port 1) while a direct-acting, pilot-assisted relief valve controls flow from

port 1 to port 2. Pilot assist at port 3 lowers the effective setting of the relief

valve at a rate determined by the pilot ratio.Other names for this valve include

motion control valve and over-center valve.
