In order to comply with government environmental regulations, Tolsma has developed its own anti-siphon valve, the Tolsiph. The Tolsiph prevents the uncontrolled flow of fuel into water or soil. This practical environmental precaution meets the requirements set out in Kiwa Guideline BRL-K916.

The Tolsiph is available in the following sizes:

1.1 MwK 1″ en 1½"
1.3 MwK 1″ en 1½"
1.6 MwK 1″ en 1½"
2.1 MwK 1″ en 1½"
