AAP Brass Swing Check Valve, 1-1/4"

This AAP brass swing check valve has a brass body, bonnet and hinge pin nut and female threaded ends. It is supplied in 9 sizes from 1/2" (15mm) to 4" (100mm). 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 1,380 kPa (13.8 bar), with a thread to AS 1722.1.
