Q641H, Q641Y Πνευματική σφαιρική βαλβίδα υψηλής θερμοκρασίας

The Q641H/Y pneumatic high-temperature ball valve consists of a metal hard-seal ball valve and a piston-type pneumatic actuator. The sealing surface uses a metal hard-seal valve seat, suitable for media with a temperature ≤500°C. The pneumatic high-temperature ball valve can be equipped with a valve positioner to input control signals (4-20mA DC or 1-5V DC) and a pneumatic power source for operation. It can also be equipped with a travel limit switch, ηλεκτρομαγνητική βαλβίδα, pressure reducing valve, and a 0.4～0.7MPa pneumatic power source to achieve on/off operation, and sends out two pairs of passive contact signals to indicate the valve’s opening and closing. The pneumatic high-temperature ball valve as a whole has advantages such as compact structure, μικρό μέγεθος, reliable operation, good sealing performance, easy maintenance, convenient installation, and strong adaptability.Especially suitable for applications involving viscous, particulate, or fibrous media. Pneumatic high-temperature ball valves are widely used in industrial automatic control systems in petroleum, χημική ουσία, educational equipment, ελαφριάς βιομηχανίας, high-pressure equipment, φαρμακευτικός, and papermaking industries for remote centralized or local control.
