Is the Ball valve 2-part with inch connection LET-LOKÂ® stainless steel, H-700 suitable for both liquid and gas service at temperatures down to -42Â°C and pressures up to 137 bar?

Yes. Ball valve 2-part with inch connection LET-LOKÂ® stainless steel, H-700 is suitable for both liquid and gas service and is rated for operation down to â42Â°C and for working pressures up to 137 bar (pressure limit depends on temperature). It is specifically designed for precision instrumentation and general process applications involving liquids and gases, constructed of AISI 316 body/ball/stem, with modified PTFE ball seals and PTFE stem seals, tested with nitrogen and certified to ISO 15848-1:2006 (E).

Can the Ball valve 2-part with inch connection LET-LOKÂ® stainless steel, H-700 be used for precision instrumentation in chemical and pharmaceutical plants?

Yes. Ball valve 2-part with inch connection LET-LOKÂ® stainless steel, H-700 is suitable for precision instrumentation in chemical and pharmaceutical plants. It is a compact two-piece medium-pressure valve designed for demanding applications and explicitly stated as usable for precision instrumentation in chemical, petrochemical, pharmaceutical, energy and process industries for liquids and gases. Key attributes supporting this use: AISI 316 body, ball and stem; modified PTFE ball seal and PTFE stem seal; tight shut-off (internal leakage â¤0.1 NcmÂ³/min); wide temperature range (â42Â°C to +204Â°C); working pressure up to 137 bar (depending on temperature); low torque and high durability; ISO 15848-1:2006 (E) certification; nitrogen pressure tested. Connection: inch LET-LOKÂ®. It is intended for pipeline installation and designed for fully open or fully closed operation.

Does the Ball valve 2-part with inch connection LET-LOKÂ® stainless steel, H-700 require routine nitrogen pressure testing before installation?

Ball valve 2-part with inch connection LET-LOKÂ® stainless steel, H-700 does not require additional routine nitrogen pressure testing before installation because each valve is factory pressure tested with nitrogen. Given its certification (ISO 15848-1:2006 (E)), specified tight shut-off (permissible internal leakage 0.1 NcmÂ³/min), and the intended use in demanding instrumentation and process applications, the factory nitrogen test provides verification of pressure integrity and leak tightness. However, standard good practice may still call for site acceptance testing after installation when system-specific checks are needed (e.g., integration with piping, welds/flanges, or customer-specific commissioning procedures). If your project or local regulations mandate on-site nitrogen testing regardless of factory tests, follow those requirements.
