Proportional Valves

Parker’s proportional valves are made for precision and endurance and are well suited for a wide variety of applications especially where accuracy and efficiency are a must. Across the complete performance range of dynamics, our proportional valves enable precise directional or flow control that react to minute changes in the fluid, perfect for industrial and mobile hydraulic purposes. Our process control valves are versatile for various applications requiring the control of steam, gas, liquids or chemicals. In all cases, our customers benefit from reliable operation even under harsh conditions.
