PRODUCT INTRODUCTION
Y-type Body Forged Check Valve is an automatic safety device device installed in the integrated control pipeline to prevent medium backflow. According to the structure form can be divided into two design forms, bolted bonnet and welded bonnet. The Y-type straight-through flow path can greatly reduce the resistance of the flow.
