Static balance valve, also known as balance valve, manual balance valve, digital lock balance valve, two-position control valve, which is by changing the spool and valve seat static balance valve (opening), to change the flow resistance through the valve In order to achieve the purpose of regulating the flow, the object of the system is the resistance of the system. The static balance valve can distribute the new water according to the designed proportion. Each branch increases and decreases proportionally at the same time and still meets the partial load under the current climate requirement Traffic demand, play a role in thermal balance. The main performance characteristics are as follows: 1, excellent regulation performance; 2, excellent cut-off function; 3, accurate to 1/10 laps open turns display; 4, the theoretical flow characteristic curve is equal percentage 5, with the opening degree of locking, non-property management staff can not change the setting state; 6, can be easily and effectively adjust the pressure and flow, supporting intelligent instrument can be Easy to display working pressure and flow, guidance and record balance adjustment program; 7, PTFE sealed, reliable sealing performance, long service life; 8, according to the percentage of its opening and before and after the valve pressure differential can be calculated through the valve Flow; 9, internal components made of stainless steel, copper alloy, anti-corrosion performance; 10, within the lift stem without leaving space for operation;
