Product Overview
Stainless Steel Wafer Spring Check Valve is a compact non-return valve used to allow flow in one direction and prevent reverse flow. The internal single disc opens automatically by forward flow pressure and closes with spring assistance when the flow stops or reverses.
Based on the product nameplate, this valve is supplied in DN150 size with SS304 body, SS304 disc, 13Cr seat, wafer connection, and PN40 pressure rating. The wafer type body allows installation between pipeline flanges, providing a compact and efficient solution for reverse flow prevention.
Key Features
Compact Wafer Design
Short face-to-face body construction allows installation between pipeline flanges with minimal space requirement.
Single Disc Spring Mechanism
Spring-assisted single disc helps close the valve quickly when reverse flow or pressure drop occurs.
SS304 Body
Stainless steel SS304 body provides corrosion resistance for industrial and utility fluid service.
SS304 Disc
SS304 disc construction supports durable operation and reliable reverse flow prevention.
13Cr Seat
13Cr seat material provides metallic seating performance for higher pressure service conditions.
PN40 Pressure Rating
Suitable for industrial piping systems requiring PN40 pressure class compatibility.
