Product Overview
Stainless Steel Wafer Type Spring Check Valve is a compact non-return valve used to allow flow in one direction and prevent reverse flow. The internal disc opens automatically by forward flow pressure and closes with spring assistance when the flow stops or reverses.
Based on the product marking, this valve is supplied in DN150 size with SS304 body material and PN40 pressure rating. The wafer type design allows the valve to be installed between pipeline flanges, providing a compact and efficient solution for reverse flow prevention.
Key Features
Compact Wafer Design
Short face-to-face construction allows installation between pipeline flanges with minimal space requirement.
Spring-Assisted Closing
Spring mechanism helps the disc close quickly to reduce reverse flow and improve non-return performance.
Stainless Steel Body
SS304 construction provides corrosion resistance for water, utility, and general industrial fluid service.
PN40 Pressure Rating
Designed for higher pressure industrial piping applications requiring reliable reverse flow prevention.
Flow Direction Marking
Direction arrow is marked on the valve body to support correct installation orientation.
Low Maintenance
Simple internal construction supports reliable operation with minimal routine maintenance.
