Product Description

Introduction

Structure:

Ultra-thin wafer design: Reduces overall length, ideal for tight installations between flanges.
Single disc: Simple, lightweight disc with a hinge or pivot mechanism for rapid response to flow changes.
Connection Type:Wafer-style (flange-to-flange), secured between two pipeline flanges using bolts (no weld ends or threaded connections).
Operation:Automatically opens with forward flow and closes via gravity or flow reversal to prevent backflow.
Advantages:

Low pressure drop and minimal flow resistance.
Compact size saves space and reduces installation weight.
Simple design for easy maintenance and low cost.
Suitable for both horizontal and vertical pipelines (flow direction dependent).
