Load holding valve

Balance valve


MCBCH


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.
