【Basic parameters] 
 Suitable medium: water, non-irritating liquid, compressed gas and nitride 
 Inlet Pressure: Maximum 25.0 bar 
 Outlet pressure: 1.2-12.0 bar (adjustable) 
 Minimum pressure drop: 1.0 bar 

 [Works] 
 Valve works based on the two corresponding force balance on each other - the force of the spring down and divide up the force. When you open the faucet water, the outlet pressure diaphragm pressure that is lower than the spring force acting on the diaphragm on the water pressure, the valve opens. Outlet pressure drop until the force on the diaphragm and spring re-balanced. As the balanced spool design, no matter the valve open or closed, the inlet pressure will not affect the outlet pressure. Therefore, the inlet pressure fluctuation does not cause fluctuations in outlet pressure, outlet pressure maintained within a certain range.
