1、 Specifications and brief description
Specification: NPS1-48 (DN25-1200), Class150-1500 (PN16-250)
Overview: Wafer type check valve
2、 Detailed information
Product Overview
The Wafer Check Valve is automatically opened and closed by the force generated by the flow of the medium in the pipeline. Its structural design is simple, the valve disc closing stroke is short, the spring is preloaded, the flow resistance is small, the sealing performance is good, the structure is short, and the installation and maintenance are convenient. It is mainly suitable for water supply, petroleum, chemical, metallurgical and other pipeline systems to prevent medium backflow.
Design and inspection can comply with standards such as API 594, JB/T 8937, API 598, JB/T 9092, etc. Fire safety design meets API 6FA requirements, and NACE anti-corrosion and acid resistance are optional.
