3/8" BSPP Double Acting Pilot Check Valve

VBD2B is a 3⁄8 BSPP pilot‑operated check valve that locks both directions of flow in a double‑acting cylinder until a pilot signal releases it. It supports flows up to about 35 l/min, has a steel body and weighs roughly 0.6 kg. While dimensions for the 3⁄8 size aren’t provided, the series typically offers a pilot ratio around 1:5.5 and a cracking pressure near 4.5 bar, with optional spring settings (3 bar or 6 bar) to adjust the release. These features make the VBD2B suitable for stabilizing hydraulic loads in systems that need dependable lock‑off capability.

Five key specifications

• Port size: 3⁄8 BSPP threaded ports.

• Flow capacity: Rated for maximum flow of 35 l/min (≈9.2 US gpm).

• Pilot ratio and cracking pressure: Typical VBD series pilot ratio is about 1:5.5 with a cracking pressure around 4.5 bar (≈65 psi).

• Construction & weight: Steel‑bodied pilot check valve with an approximate weight of 0.6 kg (≈1.32 lb).

• Function: Locks a double‑acting actuator in both directions until a pilot signal is applied; optional springs (3 bar or 6 bar) allow adjustment of the pilot release pressure.
