Dutch Flow Control
Welcome to KST Soest BV, the spin-off of the Dutch water regulation specialist TBS Waterbeheersing. We are the producer of the well-known HDPE PRA penstocks, HDPE PTK flap valves and the famous RVS penstocks with the orange band.
We still sell the same products and have the same team of employees, the only thing that has changed is our brand name: Dutch Flow Control. With a name like DFC we aim to become even more known internationally, because we want to share our decades of experience in water regulation with the world. We want everyone in the industry to know about our Dutch designs, Dutch production and our specialist team.
