2. Description of accessories
a. Suction and discharge check valve
Hanbell standard check valve is gravity-driven with characteristics of large flow volume and low pressure drop. After
shut-down of the compressor, Teflon taper guider inside can simultaneously seal up the precisely machined base of
check valve by gravity force to effectively prevent return of high-pressured gas to compressor. The gravity-driven check
valve is equipped vertically. Due to limitation of space or piping requirements, alternative horizontal check valve is
accessible.
