Is the Ball valve 2-part with GZ NPT stainless steel, H-780 suitable for bi-directional flow and bubble-tight shutoff at pressures up to 137 bar?

Ball valve 2-part with GZ NPT stainless steel, H-780 . yes. The valve is a compact, two-piece medium-pressure design intended for liquids and gases in demanding applications. It is built from AISI 316 stainless steel (body, ball, stem) with modified PTFE ball seals and PTFE stem seals, rated for operation from â42Â°C to +204Â°C and working pressures up to 137 bar (temperature-dependent). It is designed for fully open or fully closed operation, offers low torque, high durability, a permissible internal leakage through the ball seal of 0.1 NcmÂ³/min, and each unit is nitrogen pressure-tested and ISO 15848-1:2006 (E) certified. Implications: - Bi-directional flow: Suitable. The two-piece ball design and symmetrical construction allow flow in both directions. - Bubble-tight shutoff: Achievable. The modified PTFE ball seal and the quoted internal leakage limit (0.1 NcmÂ³/min) support bubble-tight performance under specified conditions. - Pressure up to 137 bar: Acceptable, provided temperature and application conditions fall within the valveâs ratings (working pressure is temperature-dependent). Ensure the specific operating temperature, media compatibility, and installation details meet the manufacturerâs rated limits.

Can the Ball valve 2-part with GZ NPT stainless steel, H-780 be used for precision instrumentation in pharmaceutical and petrochemical plants?

Yes. Ball valve 2-part with GZ NPT stainless steel, H-780 is suitable for precision instrumentation in pharmaceutical and petrochemical plants. It is a compact two-piece, medium-pressure valve designed for demanding chemical, petrochemical and pharmaceutical applications for liquids and gases. Features supporting precision use include AISI 316 body/ball/stem, modified PTFE ball seal (internal leakage â¤0.1 NcmÂ³/min), PTFE stem seal, wide temperature range (-42Â°C to +204Â°C), working pressure up to 137 bar, low torque, high durability, and ISO 15848-1:2006 (E) certification. It is pressure-tested with nitrogen and intended for pipeline installation with GZ NPT connection.

Does the Ball valve 2-part with GZ NPT stainless steel, H-780 support cryogenic service down to -42Â°C?

Yes. Ball valve 2-part with GZ NPT stainless steel, H-780 supports cryogenic service down to -42Â°C. The product specification lists an operating temperature range from -42Â°C to +204Â°C, materials (AISI 316 ball and stem, modified PTFE seals) and pressure testing suitable for demanding applications, indicating suitability for use at -42Â°C.
