1. Application

The high velocity relief valve with forced closing device generally used in chemical tanker or oil tanker. For some special chemicals, there are special requirements during the loading process and during the voyage. Some are required to achieve zero leakage during the course of the voyage after loading. The high velocity relief valve is required to meet the zero leakage requirement after the forced closing device is installed. Of course, the forced closure can also be used to deal with any special circumstances that require closure.

2. Material

valve body: stainless steel
valve seat: stainless steel 0Cr18Ni9  SUS304
flame screen: stainless steel 00Cr17Ni14Mo2  SUS316L

Your special material requirement can be met, such as cast steel, stainless steel 304, stainless steel 316L etc.

3. Nominal Size & Pressure

diameter:DN50—DN250

pressure:(1) oil tanker:-3.5Kpa to 14Kpa; (2) chemical tanker:-3.5Kpa to 20Kpa.

4. Features

(1). The High Velocity Relief Valve is required to meet the zero leakage requirement after the forced closing device is installed.

(2). Adjustable outside opening and closing pressure without exhausting vapor gas.
