Key Specifications / Features

Model No. : 184101001

This is a bolted bonnet swing check valve. It is an automatic valve that relies on medium flow force to open and close the disc automatically; no manual actuator is required. It only permits fluid to flow in one direction and prevents reverse flow to protect upstream pipeline equipment. The flanged ends are designed for easy installation and disassembly for on-site maintenance. The valve body is made of ASTM A216 WCB cast carbon steel, suitable for medium-temperature fluid service. It complies with the ASME B16.34 design standard and the API 598 valve test standard.
