Check Valve Insert, Poppet Type
A thread-in poppet check valve insert that screws directly into a standard BSPP port in a manifold or valve block. No separate cavity machining is required — the insert seats against the existing port face, providing an integrated check function with a very low installation profile.
The poppet design delivers reliable sealing and consistent cracking performance. Available in four BSPP sizes, all rated to 350 bar.
