CHECK VALVES

Check valves, also known as one-way valves, non-return valves, or single-flow valves allow fluid to flow in the direction of the arrow but do not allow fluid to flow in the opposite direction to that of the arrow.

Our non-return valves are piston-operated and ideal for instrumentation. In addition to not allowing the fluid to circulate in the opposite direction, they have a system that prevents the circuit from being unloaded. In other words, the fluid will not circulate in the direction of the arrow if it does not overcome the set pressure of the valve. Normally this pressure is set at 0.5 bar but it can be modified on request.

Check valves with free flow in one direction and block in the other to eliminate the effect of backpressure in the pneumatic and hydraulic circuits. Internally these valves are formed by an automatic closing system by spring piston.
