AAP Stainless Steel Swing Check Valve, 1-1/4"

This AAP stainless steel swing check valve has a CF8M stainless steel body, bonnet and disc, a 316 stainless steel hanger pin and plug, a PTFE plug gasket and female threaded ends. It is supplied in 8 sizes from 1/2" (15mm) to 3" (80mm).

A swing check valve lets liquid flow through in a nearly straight line, like a gate valve, and stops it flowing back. A disc hangs on a hinge, so forward flow swings it open and reverse flow swings it shut against the seat. This type is commonly used on pipelines moving liquid by gravity or by pump. The maximum working temperature is 200°C and the cold working pressure is 1,400 kPa (14 bar), with a thread to AS 1722.1. AAP calls it a 316 BSP check valve in its table heading.
