Product Description
CASTEL 6570/7 Ball Shut-off Valve – 7/8", 22mm, soldered
Castel 6570/7 is an industrial ball valve from the Classic Line series, designed for refrigeration installations using ASHRAE 34:2019 A1 refrigerants. The full-bore ball (O 19 mm) and soldered ODS 7/8" (22 mm) connection provide minimal pressure drop and a tight, durable pipeline connection.
Key features and benefits
- Full-bore ball (O 19 mm) – minimal flow resistance (Kv = 29 m3/h), which improves the energy efficiency of the entire system.
- Soldered ODS 22 mm connection – durable, leak-proof joint without the sealing risks associated with threaded connections.
- Working pressure PS 45 bar (600 psi) – safe operation even in high-pressure systems with R410A refrigerant.
- Temperature range –40°C to +150°C – fully suitable for both freezing and air conditioning applications.
- ASHRAE 34:2019 A1 compliance – compatible with HCFC, HFC and HFO refrigerants, including modern low-GWP blends (R448A, R449A, R452A, R513A, R515A, R515B).
