The Hydra-Tech hydraulic flow controller from Hydra-Tech Pumps allows users to dial in the flow coming from many hydraulic power sources. Adaptable for use on skid-steers, backhoes, other onboard hydraulic power and even an oversized power pack, the controller has a built-in check valve to prevent reverse flow, and an anti-cavitation check valve that allows the impeller or tool to wind down, preventing overspeed, sudden stops and hydraulic shock. The pressure-compensated flow restrictor limits maximum flows, while the adjustable flow control valve fine-tunes the hydraulic fluid output. It is available in two flow ranges, 0 to 8 and 0 to 16 gpm, and handles input pressures to 3,000 psi. 570/645-3779; www.hydra-tech.com.
