January 4, 2019

If you’re searching for a supplier of the industry’s best proportional valves, FEMA Corporation has you covered. With a half-century of experience, we’ve worked tirelessly to produce – and continually improve – our products, earning us a reputation as one of the most dependable, quality-focused suppliers on the market. Serving a range of sectors, including agriculture, construction, and rapid transit, we have built our company around providing top-quality hydraulic solenoid valves, manifolds, and other electrohydraulic components. In today’s post, we’re going to take a closer look at our direct drive proportional valves.

What they are

Our low-frequency valves are direct drive proportional vales with two-, three-, and four-way pressure, flow, or position control. Most commonly used in transmission, PTO, brake, and SCV controls, they are also utilized in hydraulic cooling applications. The solenoid armature of FEMA’s valves directly contacts the valve spool, with the spool driven by the force from the armature.
