DESEINOR DSSY-H100P stainless steel PTFE lined bottom valve for chemical & oil tankers, shear groove anti-leak design compliant with ADR & 49CFR178.345-8, fits corrosive liquid, gasoline, methanol media.
DSSY-H100P Stainless Steel Bottom Valve under DESEINOR products is a core safety component installed at the bottom of chemical tank trucks, tank containers and oil tankers, which ensures safe and efficient discharge of media.This emergency shut-off
valve is specially designed for chemical corrosive liquid applications, featuring excellent flow capacity and fast response
performance in emergency scenarios.
This product series features an internally fully-coated structure made of PTFE material, making it compatible with a wide
range of media—including corrosive liquids, low-temperature gases, biodiesel, gasoline, ethanol, and methanol. Equipped
with chemical-resistant seals, it significantly enhances media compatibility and durability.
This bottom valve is built-in with a shear groove structure, whose design and testing fully comply with the standards of U.S.
Federal Regulation 49CFR178.345-8 and the Agreement concerning the International Carriage of Dangerous Goods by
Road (ADR).In the event of a vehicle collision, the valve body will separate along the shear groove while maintaining a tight
seal with the tank flange, preventing medium leakage and protecting the integrity of the valve mechanism inside the tank.

Core Functions：
1. The valve body housing is fabricated from 304 stainless steel, making it resistant to corrosion in outdoor environments, as
well as in salt spray or rainwater exposure conditions typical of chemical industrial parks.
2. Integrated built-in cylinder spring reset mechanism with automatic valve closure upon air release – enhances safety
during use.
3. Both the valve disc and valve seat are made of PTFE material to isolate the metal from corrosive media; the soft-seal
design provides excellent leak-proof performance.
