About Us

Since the early 1900's, Graham-White has partnered with transportation companies and industry alike to develop heavy-duty pneumatic and electro-pneumatic valves and accessories. We are also the world technology leaders in the drying of compressed air for locomotives and rail transit vehicles. However, the quality products and know-how shown on this site represent only a portion of what we make and who we are.

As custom innovators and manufacturers, we are always poised to expand our knowledge base by developing new markets and products in conjunction with our partnering clients. Our promise is to provide reliable solutions on time.
