ZF6-25B series 2/2 explosion-proof refrigeration solenoid valve

Introduction

This series of explosion-proof products are pilot-operated two-position, two-way solenoid valves. They incorporate a specially engineered diaphragm made from polytetrafluoroethylene (PTFE) as the sealing element. These valves are widely used for automated control in liquid pipelines, suction pipelines, and hot gas pipelines where ammonia or fluorinated compounds serve as refrigerants.
