FCS014 Forged Steel Horizontal Lift Check Valve Class-1500 (Socket Weld / Screwed)

INTRODUCTION

Leader forged steel check valve is to provide with single disc. With the force of medium, the disc will automatically open or close. When the media stops the flow, the disc will be closed under its own force. No manual intervention is involved in the whole process Check valve is mainly to prevent the media reverse flow and ensure one-way flow of media channels only. It prevents accidents while a sudden loss of power in the pipeline medium such as the power equipment like pump damages, and the medium reserve flow against power source.
