The Sun Hydraulics CKECSBN (CKECSBN) is a vented pilot-to-open check valve, equipped with an SAE4 external pilot port and a sealed pilot. This precision-engineered valve features a Delrin seat, known for its high stiffness, low friction, and excellent dimensional stability. The CKECSBN model is designed to allow free flow in one direction and blocked flow in the reverse direction until pilot pressure is applied. It is particularly useful in hydraulic circuits requiring reliable check functionality with the added control of an external pilot override. This configuration makes it suitable for applications where flow control must be managed meticulously and where the durability of valve components under varying conditions is critical. The use of Delrin for the seat enhances the valve's performance by providing a tight seal and resistance to wear, contributing to the longevity and reliability of the system in which it is integrated.
