Product Description
Electric Flow Proportional Valve Control Valve for Steam 

Our proportional values are featured by simple structure, elegant profile, dependable quality, accurate proportion, steady operation, and reduction of both dynamic and static pressure.

 
Thess valves use the pressure difference caused by different sectional areas of the two ends of piston inside vlave body to change the back pressure of valve for pressure reduction.
 
Application
 
HVAC system
 
Heating system
 
Water treatment system
 
 Industrial equipments
 
Characteristics
1. Adopting the fashionable LUDV control technology of the world, it can provide the max displacement according to the oil pump to realize proportional flow distribution of different execution mechanisms;
2. The flow distribution is not relative to the load pressure;
3. Valve lever uses circular orifice, having a more precious flow, more stable movement, to meet various of demand in Different working case;
4. Using median position low pressure relief mode is expandable to the variable displacement pump system in which the Variables cannot reach zero displacement, also applicable to constant delivery pump system at the same time.
5. Adopting multi-piece overlay, multi-channel proportional flow valve set can be formed by overlaying of working Couplets, to meet customer's demand, maximum to 8 couplets;
6. Closed core type used in variable pump, built-in load holding valve, built-in tank back pressure valve.
