FastLock
38000-2 is the normally
closed 2/2-way solenoid valve designed by OLAB for professional
refrigeration systems using A3–A2L refrigerants. It combines a robust
design with maximum installation simplicity thanks to the patented FastLock
A3–A2L system, which allows for a mechanical connection without welding,
ensuring permanent sealing without the need for specialized personnel or
equipment.
The valve
body, made of high-precision yellow brass, houses a stainless steel AISI
304 tube and a PTFE sealing system. The entire assembly is
engineered to withstand extreme pressure and temperature conditions. The
double O-Rings, positioned at every critical point, are made of HNBR
100% PFAS-FREE compound certified by OLAB, ensuring maximum compatibility
with A3–A2L refrigerants and reliable sealing even under intense duty cycles.
An additional sealing element, specifically developed for these systems,
ensures leak-free operation even under thermal and chemical stress.
The operating stem is made of AISI 303 stainless steel,
guaranteeing mechanical resistance and durability. The 30 mm coil, with ø14
mm bore, is class H (180°C) and IP67-certified, ensuring
protection in humid, dusty, or splash-prone environments. The entire component
is UL 207 and UL 429 certified.
The FastLock
connection completely eliminates the need for tube welding. The pipe is
inserted with a reinforcement sleeve in stainless steel into the fitting
body, and by tightening the nut to the proper torque, the ogive deforms and
locks the tube in place. The AST groove on the reinforcement sleeve
ensures secure mechanical retention, even in the presence of high-pressure
cycles, while maintaining perfect sealing. Maintenance is just as simple:
all operations are mechanical, requiring no cutting or welding. This
significantly reduces system downtime, increases safety during
service, and preserves the integrity of the component and its
sealing elements over time.
Each valve
is individually 100% helium tested in a dedicated OLAB facility. Laser
marking of the date and serial number confirms test compliance and
enables lifetime traceability of recorded performance data.
FastLock 38000-2 is the ideal choice for professionals seeking a reliable,
sustainable, and technically advanced solution for refrigeration systems
using A3–A2L refrigerants.
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.
FAST
LOCK A3-A2L CONNECTION SYSTEM
OLAB’s patented system eliminates the need for welding pipes, ensuring a rapid,
clean, and safe connection that delivers a perfect mechanical seal—without
specialized labor or tools.
