Proportional Valves are used for adjusting flow volume of liquids or gases by altering their spool position. These use force controlled or stroke regulated solenoids for changing their spool location. All parts of these valves are hardened to minimize their wear rate. These consist of pilot orifice screen as their safety attributes, air bleed screws, weather proof coils and cartridges. The special design of these valves enables their operator to detect null zone easily. Solid structure, minimal pressure drop level and corrosion proof zinc plated cartridge surface are the main attributes of these valves. We are a prestigious wholesaler/distributor of Proportional Valves.
