Features & Benefits

Velan’s pilot-operated check valve design is a flexible and reliable solution. It enables reverse flow, and provides a safe alternative to control hydraulic and pneumatic systems during maintenance and normal operations. It also prevents overpressure and malfunction, and it’s quick and easy to maintain.

Additionally, it offers customizable cracking pressure, pilot-to-check valve pressure ratio, and working pressure–all in a single product with lasting quality.
