2. Description of accessories
a. Steps or step-less capacity control system
b. Compatible steps and step-less capacity control system
For customers’ ease of stock control, possible modification of capacity-control logic in the future, or other special
requirements of capacity control, Hanbell deliberately designs devices for stepless/step dual capacity control as nonstandard
accessory for customers’ choices. Logic of stepless/step dual capacity control is basically identical to those of stepless or step
capacity control respectively.
c. Suction and discharge check valve
Hanbell standard check valve (vertical type) is gravity-driven with characteristics of large flow volume and low pressure
differential. After shut-down of 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
also available.
