INTRODUCTION

The safety valve automatically discharges fluid in case of a pressure exceeding a certain level in the refrigeration system to reduce pressure below the set pressure for system protection. It is the best product that is made of heat treated materials, which are also precisely processed and plated, not only to ensure corrosion prevention but also to ensure accurate operation for a long term period. We provide safety valve pressure setting and re-inspection services.
