Introduction

 

Water safety valves usually require that when the safety valve is discharged, the pressure drop in the inlet pipeline should not exceed 50% of the valve opening and closing pressure difference (the difference between the set pressure and the reseating pressure), and generally not exceed 2% to 3% of the set pressure. When the resistance of the inlet pipeline is too high, it can cause valve oscillation (frequent opening and closing) and insufficient displacement.

 

Suitable for equipment such as heavy coal tunneling machines.

 

Opening pressure 1.2MPa

 

 

 

Secondary safety valve YAS-30
