DSSY-PQF-DN200 Pressure Release Valve/Decompression valve

Product Overview

Pressure Release Valve/Decompression valve – This DN200 tank top pressure relief valve is a dedicated pressure safety protection valve for oil tanks and liquid tanks under the DESEINOR brand.

It is mainly installed on the tank top of storage tanks and tankers as an overpressure safety relief device to ensure the pressure bearing safety of tanks, suitable for the storage and transportation of oil products and hazardous media.

The valve adopts a split composite structure: the lower part is an aluminum alloy flange base for convenient flange installation and fixing on the tank top; the upper part is equipped with a black sealed pressure-bearing end cap with built-in elastic sealing components. The valve maintains sealing under the set pressure. When the pressure inside the tank exceeds the preset opening value, the valve cap opens automatically for pressure relief. When the pressure drops to a safe range, the valve closes automatically to prevent continuous medium leakage, effectively avoiding the risk of tank deformation and rupture caused by overpressure.

With a compact overall structure and direct flange mounting design, the valve features easy installation and stable sealing performance. It resists oil and gas corrosion and aging, compatible with gasoline, diesel and light chemical media. It meets the explosion-proof safety specifications for hazardous goods storage and transportation, and can be matched with the pressure safety protection system of storage tanks and large liquid tankers.
