The Sun Hydraulics CKECSEV (CKECSEV) is a vented pilot-to-open check valve featuring an SAE4 external pilot port and a sealed pilot system. This particular model is designed with a Delrin seat, which enhances its durability and performance in various hydraulic applications. The CKECSEV model is engineered to allow free flow from the inlet port to the outlet port while normally blocking flow in the opposite direction. However, flow from the outlet to the inlet can be permitted when an external pilot pressure is applied, which overrides the check feature. This capability makes it suitable for applications requiring reliable control over fluid movement in hydraulic systems, where preventing reverse flow is critical until intentional pressure signals are given. The use of Delrin for the seat material provides low-friction properties and resistance to wear, which are essential for maintaining valve integrity and responsiveness over time.
