Check & Counterbalance Valves

Check & Counterbalance Valves

Check valves are used in hydraulic and pneumatic systems to allow fluid to flow in only one direction, preventing reverse flow that could damage components or disrupt system operation. They help maintain pressure, protect pumps and actuators, and ensure smooth, controlled fluid movement.

Counterbalance valves are used to hold and control loads, especially in vertical or gravity-affected systems. They prevent free-fall or uncontrolled descent of actuators by maintaining backpressure, ensuring smooth, safe, and stable load control. 

These valves are essential in applications like hoists, cranes, and mobile equipment where load safety and control are critical.
