Micro-opening Safety Valve

Micro-Opening Safety Valve Overview

A micro-opening safety valve is a specialized type of safety valve known for its relatively small opening height and discharge volume. To elaborate further, the specified opening height (h) of the valve disc falls within the range of (d1 / 40) to (d2 / 20), where (d1) represents the diameter of the valve seat's throat. This valve comes with two types of sealing surfaces: flat and conical. The calculation of their discharge areas is based on the surface area of the cylindrical region or the conical curtain formed between the valve disc and the valve seat.

Advantages of this Design

The key advantage of this micro-opening safety valve design lies in its simplicity, which facilitates manufacturing, maintenance, and test adjustments. This micro-opening safety valve is particularly well-suited for situations characterized by minimal discharge requirements, significant back pressure, and a stable system pressure.
