Azbil’s low-emission gland packing system achieves the low level of leakage required by ISO 15848-1:2015*, the only international standard for control valve gland and gasket seal performance, and it is certified to CC3, the highest endurance class, by a third-party certification organization. Many countries and regions, including China, Taiwan, Thailand, and the U.S., have regulations that limit the emission by industrial facilities of VOCs, which are a cause of air pollutants such as fine particulate matter (PM 2.5) and photochemical smog.
Azbil Corporation, Japan announced that it
began to sell control valves with a low-emission gland packing system
that reduces the leakage of volatile organic compounds (VOCs) Azbil’s low-emission gland packing system achieves the low level of
leakage required by ISO 15848-1:2015
Driven by the Group philosophy of “human-centered
automation,” the Azbil Group with over 100 years in existence, strives to utilizes its measurement and
control technologies to realize safety, comfort and fulfillment in
people’s lives whilst contributing to the global environment.
Internationally, it runs a Building Automation business for the building
market, and an Advanced Automation business for factories and plants.
Additionally, in Japan it operates a Life Automation business for
markets closely connected with people’s lives, such as lifelines and
health.In each field the Group pursues its business with an integrated
structure that combines everything from planning and development to
marketing and maintenance, and is capable of responding rapidly to
customer needs.
Azbil’s low-emission gland packing system achieves the low level of
leakage required by ISO 15848-1:2015 the only international standard
for control valve gland and gasket seal performance, and it is certified
to CC3, the highest endurance class, by a third-party certification
organization. Many countries and regions, including China, Taiwan, Thailand, and the
U.S., have regulations that limit the emission by industrial facilities
of VOCs, which are a cause of air pollutants such as fine particulate
matter (PM 2.5) and photochemical smog. These regulations place limits
on the VOC leakage from control valves and require companies to control
the leakage. By using control valves incorporating a low-emission gland
packing system certified under ISO 15848-1, companies can more easily
comply with the regulations.
1. Certified to CC3 (highest endurance class) under ISO 15848-1:2015
The low-emission gland packing was tested by a leading third-party organization and was certified to have a seal performance meeting the requirements of ISO 15848-1:2015, as well as having the highest level of endurance (CC3 class) specified by the ISO standard. To be classed as CC3, Azbil’s low-emission gland packing system had to keep leakage under the specified level even after 100,000 cycles.2. Improving industrial safety and productivity.
The low-emission gland packing system can reduce fluid leakage from control valve packing glands.- It contributes to better industrial safety at sites where foul odor is generated, or where eye-irritating fluid is handled.
- By reducing the leakage of fluid used for power or for products, it improves productivity.
3. Longer maintenance cycle.
The system’s live-loaded packing system uses Belleville springs to continually apply the appropriate amount of force to the packing and prevent relaxation of the gland. It is especially effective for control valves that are prone to leakage, such as valves that operate frequently or valves with alternating hot and cold thermal cycles.* ISO 15848-1: “Industrial valves – Measurement, test and qualification procedures for fugitive emissions – Part 1: Classification system and qualification procedure for type testing of valves.”
