In the beginning the first Check-All® valve was designed and built for use as a pump foot valve; the year was 1958. Since then Check-All® has grown from an idea to a reality; from one valve to many series of valves; from one use to multiple uses; from one material; to a variety of materials and from one man to a factory. Check-All®
has grown in all respects — but one element remains the same — SERVICE TO EACH
CUSTOMER. We will never permit this to change.
