Counterbalance valve is a special function of the valve, it has good flow characteristics, the valve opening instructions, opening locking device and for the flow measurement of small pressure valve. The use of special intelligent instruments, enter the valve model and the opening value, according to the measured pressure signal can be displayed directly through the balance valve flow value, as long as each branch and user access to install the appropriate specifications of the balance valve, And with a dedicated intelligent instrument one-time debugging, you can make the user's flow to set value.
