Single Disc Wafer Check Valve

Product Overview
The Single Disc Wafer Check Valve is a new-generation lightweight one-way flow control valve developed by ZTE VALVE, specially designed for large-flow, fast-switching and space-limited pipeline working conditions. Different from double-disc wafer check valves and traditional flanged check valves, this valve adopts a single integral swing disc structure with an ultra-thin wafer body, featuring simpler mechanical structure, larger flow area and faster opening response.
Clamped directly between pipe flanges without extra connecting space, the single disc wafer check valve saves installation space and reduces overall pipeline load. Made of high-quality stainless steel, the valve body is resistant to rust, corrosion and high temperature. Relying on fluid thrust and disc gravity to realize automatic opening and closing, it effectively prevents medium backflow, stabilizes pipeline pressure and ensures safe and efficient operation of water supply, industrial circulation and fluid transmission systems.
Unique Product Features & Core Advantages
•Integrated Single Disc Structure — Adopts one-piece swing disc design with fewer internal parts, simpler mechanical logic and lower failure probability compared with double-disc structures. The overall structure is more stable and durable for long-term continuous operation.
•Ultra-Large Flow Passage — The single disc opening angle is larger with no flow obstruction, forming a full straight flow channel. It effectively reduces flow resistance and pressure loss, perfectly suitable for large-flow fluid transmission pipelines.
•Ultra-Thin Wafer Body & Lightweight — Slim wafer-type body design minimizes installation space occupation. The lightweight structure reduces pipeline bearing pressure, ideal for dense pipe layout and equipment built-in installation scenarios.
•Fast Response Opening & Closing — The single swing disc features flexible movement and sensitive induction. It opens instantly with forward fluid flow and closes rapidly to block backflow, avoiding pipeline pressure back surge.
•High-Precision Sealing Performance — Matched with high-elasticity sealing gaskets and precision-lapped valve seat surface. It achieves tight sealing and zero backflow under rated pressure, ensuring stable one-way fluid operation.
•Strong Environmental Adaptability — Full stainless steel construction provides excellent anti-corrosion, anti-oxidation and rust-proof performance, adapting to clean water, industrial water, oil and weak corrosive media.
•Free Installation Direction — Supports both horizontal and vertical pipeline installation with no direction limitation, bringing great flexibility for on-site engineering construction.
•Low Maintenance & High Cost-Performance — Simple internal structure without vulnerable accessories. It requires no daily lubrication or frequent maintenance, greatly reducing later operation costs for pipeline systems.
