Proportional Pressure Relief Valve

Originally designed for a braking system on a heavy equipment trailer, this direct-acting, normally open, continuously variable pressure relief valve can be designed to operate over various pressure ranges to optimize controllability. TLX's magnetic technology features allows for a smaller package and/or greater efficiency.
