Needle valves are designed for use as speed controls where a reverse flow check valve is not needed. They may be used to control flow in both directions. Brass valves are ideal for pneumatic and medium-pressure hydraulic applications. Steel valves are for high-pressure hydraulic applications. Metering valves allow high precision metering and flow shutoff.
Hydraulic flow control valves provide precision flow control in 1 direction, and automatically allow unrestricted free flow in opposite direction. Adjustable-flow control valves feature pressure-compensated operation that varies speed smoothly over the full range. Once speed is set with the lever, it remains constant regardless of load variation.
