High Pressure Cryogenic Safety Valve Liquid Nitrogen Relief Valve OEM

• A slightly open safety valve refers to a safety valve with a relatively small opening height and a relatively small discharge. Specifically, the specified opening height h of the valve disc is between d1/40 and d2/20 (d1 is the diameter of the throat of the valve seat).
• There are two types of valve sealing surfaces: flat and conical. Its discharge area is calculated based on the area of the cylindrical surface or conical curtain formed between the disc and seat.
• The advantage is that the structure is simple, and the manufacture, maintenance and test adjustment are relatively convenient. It is suitable for occasions with small flow rate, large back pressure and stable system pressure.

This type of safety valve is mainly used for the safety discharge system of cryogenic liquid storage and transportation equipment. It has the characteristics of sensitive switching and reliable sealing, and is especially suitable for small volume equipment.
