ՀՏՀ

Q1: What is the difference between a triple-offset butterfly valve and a centric (concentric) butterfly valve?

Ա: In a centric butterfly valve, the stem is located at the center of the valve body; the disc sealing surface remains in constant contact with the seat during opening and closing, resulting in high friction and a shorter service life. A triple-offset butterfly valve features three offsets that ensure the disc immediately separates from the seat upon opening and only makes contact at the final moment of closing—virtually eliminating friction and wear, while providing zero-leakage sealing and an extended service life.

Q2: What is the difference between metal-to-metal (hard) sealing and soft sealing?

Ա: Metal-to-metal sealing (hard sealing) withstands extreme temperatures (-196°C to +550°C) and offers resistance to wear and corrosion, making it suitable for high-pressure, high-temperature, cryogenic, and abrasive media applications. Soft sealing (օր., EPDM, PTFE) offers superior sealing performance (zero leakage) but has a limited temperature range (typically -20°C to +200°C) and is not suitable for high temperatures or abrasive media. Triple-offset metal-seated butterfly valves are ideal for demanding operating conditions requiring exceptional sealing integrity and reliability.

Q3: What is the operating temperature range for this valve?

Ա: The operating temperature range is -196°C to +550°C, covering a full spectrum of applications from cryogenic LNG service to high-temperature steam and process heating. This makes the valve an ideal choice for various extreme-temperature applications, including liquefied natural gas (LNG), cryogenic gases, high-temperature steam, and hot oil systems.

Q4: What does compliance with NACE MR 0103 and MR 0175 նշանակում է?

Ա: NACE MR 0103 and MR 0175 are material standards used in the oil and gas industry for sour service environments containing hydrogen sulfide (H₂S). Compliance indicates that the valve materials have been specially treated and tested to resist sulfide stress cracking (SSC) and hydrogen-induced cracking (HIC) in acidic environments, ensuring safe and reliable operation in oil and gas processes involving H₂S.

Q5: What actuation methods are supported for this valve?

Ա: Options include handwheel (manual, for small sizes), worm gear (self-locking, for DN150 and above), electric actuator (remote/modulating control), pneumatic actuator (rapid response), and hydraulic actuator (high thrust). The top flange complies with the ISO 5211 ստանդարտ, allowing for direct actuator mounting without the need for additional adapters.
