The Spring-Loaded Piston Check Valve provides reliable back‑flow protection in hydraulic systems. It uses a spring‑assisted piston to close quickly when pressure reverses. Available with BSP threads from 1/8″ to 2″, it is rated 400 bar up to 3/4″ and 320 bar for larger diameters. Constructed from forged steel, it suits hydraulic power units, mobile equipment, industrial presses, and agricultural machinery. Immediate stock and fast delivery are available.
