STAUFF manufactures several types of hydraulic valves. The in-line mounted throttle and flow control valves are made in DV, which provides fluid control and/or shut-off in both directions, and DRV, which shuts off in one direction and allows free flow in the reverse direction; the manifold mounted throttle and flow control valves have the same options in their two models, DVP and DRVP. In addition, throttle valves (cartridge assembly), check valves (in-line mounting), and gauge isolator valves, which protect against gauge overload, are also available.
