Notes:
Rotalock Revolution is the flanged ball valve made of CW614N–OT58 brass with stainless steel components and 100% PFAS-FREE OLAB-certified double HNBR sealing gasket designed by OLAB for A3-A2L applications, with a P355N weld-on connection for tanks.
Technical features:
COMPATIBLE A3–A2L REFRIGERANT GASES
HFC, HFO, and HFO/HFC blends: R404A, R407C, R410A, R507, R32, R134a (up to +125°C / 257°F).
HFO and HFO/HFC blends: R1234ze, R448A, R449A, R450A, R452A, R1234yf.
HC: R290, R600, R600a.
Products equipped with HNBR seals must not be installed on systems using HCFCs (R22) or any refrigerants mixed with mineral oils or alkylbenzene lubricants.
Our HNBR compound seals have been specifically designed and manufactured for compatibility with A3 and A2L refrigerant gases (as defined in ASHRAE Standard 34). However, due to the countless variables involved in real-world applications—such as pressure, temperature, and mixing ratios—an application-specific validation on the system is always required.
ENTIRELY MADE USING ULTRA-HIGH-PRECISION MACHINES
100% NO LEAKAGE
Absolute sealing over time. A system that is reliable, efficient, profitable and 100% green
NO STRUCTURAL WELDING
Eliminating long-term sealing issues caused by thermal stress
